To complete a task in the list view, just hold it for a moment and fling it from the left to the right.
To edit a task fling it from the right to the left.

NOTE: This task app doesn't support recurring tasks yet. You'll see recurring tasks, but you can not edit single instances. Any changes you make will apply to the entire series! Please keep that in mind.

It works in Android 2.x, but it's optimized for Android 4.x. Support for Android 2.x will be improved in future releases.

Features still to come:
* more translations
* support for recurring tasks
* support for alarms
* support for categories
* sortings and filters
* many more

Please don't rate missing features, but only features the app already has. The app is still under development and lots of fancy stuff is still to come.

At present the app doesn't use the "read contacts" permission. This permission has been added in advance for future releases. It's planned to support adding attendees to tasks and to provide auto-completion for the contacts.

Reviews From google play store

This task app is simple but that is fine as it is fairly reliable, bug free and gets the job done. Main issue is that List View and Date View are the same. Need List View to be exactly that and ignore associated task dates.

This app is nearly perfect, but how do you create a new List via app to be synced to cloud. Everytime I add one it says it will be local only. How do I change it? If this feature is added or explained to me I'll update to 5 stars.

Simple and elegant for the features it has. Excited to see recurring tasks and alarms and categories! One question, and I can't tell if I'm just dumb, but how do I connect this to my Nextcloud instance for a synced list?

Nice overall, albeit it lacks recurrent tasks. Notifications are broken, that's a spoiler. The actions work at random.

Phone vibrates for no reason Edit: The bug seems to be fixed for me

Great but needs support for recurring reminders.

I use every time. Good and simple UI

It is an amazing app. And the best part is that it is open-source and developed on Github. It will be amazing if the developers could add these two features: Night-mode (or dark theme), and a task tracker feature wherein the app will simply calculate the avg progress % per day required to complete any particular task and show based on that whether the user is ahead of schedule or behind schedule. Thanks a lot.

Just perfect in every way. Good job.

Great app, sync's with my Nextcloud using Davx and has plenty of features.

Great features, and supports etesync - plus in my book :)

The app works fine for syncing tasks from CalDav server that the calendar app, I'm using, is not capable of. There are, however, a few things that really annoy me. 1. When I complete a task, usually from notification bar, I get a notification that the task was completed. Why?? This is annoying but not critical. 2. What is critical is that after phone restart, I automatically get a barrage of notifications of all completed tasks in history. Now there are maybe 50 of them but I can't imagine what it will be like when there are a 1000 of them. That will probably just crash the phone. 3. I wasn't able to find a setting that would set a week to start with Monday as it is normal in Europe. As the maker of the app seems German, I don't understand it at all. It is really annoying to have all other apps using Mo-Su week and only this one uses Su-Sa.

Since last update the notifications got a disaster. I deal with tons of tasks and was happy with the grouped notification view in taskbar. Now the notifications are all sepparate and slow down my honor8 to an unusable level. How to get back the grouped view?

This is a basic task manager at the moment, it doest even support task recurrence yet. It works with NextCloud, which is what I wanted, and is clearly still being updated. Great work. Edit 1: There are fundamental features missing for any task app. Categories and recurring tasks being the most notable. Edit 2: Recurring phone vibration for no apparent reason.

While not exactly good, unbelievably this app seems to be the best option for syncing caldav tasks with Nextcloud. For five stars please add: Option to use checkboxes next to tasks instead of swiping. Ability to hide the tabs across the top, these waste a lot of space and distract focus. I just want a checklist with caldav sync. Some theming or colour options other than the default green.

Worked great for the first month, suddenly stopped allowing me to add new tasks. Sent multiple feedbacks to the developer over the course of a month and received no response, plus the problem remains. Uninstalling it, but first I must migrate to another application, and there's no way for me to export my tasks... So I have to manually rebuild everything. Very disappointed!

The support is non existent or useless. There is a funny guy called Silvio Ankermann that replied my tickets and that only provides from time to time and after intensive follow-up some useless information (e.g. asking me whether I have received a previous message instead of addressing the issue right there and right away) and then disappears for several weeks. Very disappointed!

I love how concise and easy this was to use! I wish I could sync this data with my Google tasks or something, I just have a hard time using any new data silos! I have emailed the developer with a bunch of questions, looking forward to hearing from him!

Great app. To be perfect, still need Recurring Task option as well as section for Past Due separate to Today's tasks. Today' tasks should be first on the Chronological list as well (vs currently past due tasks are grouped with today's tasks and past due tasks show first)

Pinning a task does not work. I would really like to pin tasks from the app in my notifications, but the "Pin task" button does not do anything.

Exact what I need, simple, easy, accurate, compatible with all platforms, perfect follow-up and record, easy and quick accessible and really free with no ads. If we can make copy of tasks, that will be very good.

It's weirdly difficult to swipe away tasks for some reason. You have to long press, then swipe real quick. Checkboxes would be a nice alternative. Otherwise great!

I really love this app however it has stopped working on my phone; every time I try to save a new task the app will crash.

after heavy lags in the past, i now have random and ultra annoying vibration signals ongoing until phone reboot, even after closing the app. uninstalling this apps hels. this was a good app once. was.

Excellent, straightforward tasks app which I synchronise with SOGo mail & calendar using DAVx5. One thing I would like to see is the ability to indent checklist items.

I like it. It's vibrating in the background for no apparent reason since the latest up however, kinda weird..

Another brilliant open source app! I hope they'll add the option to push the checked/completed tasks to the bottom.

Plz add ability to modify the tasklists that are shown in widgets or make an "all" tasklist which contains them all. It really sucks to have to re-create all 2 widgets whenever a tasklist gets created or renamed.

Works well with webdav (Own/ nextcloud), you even get a nice clean widget to remind you of all the stuff you should have done.

Great app, needs a little more work to be perfect.

Simple, neat and reliable. love the new design!

Would appreciate another tab (like due/starting/priority/progress) that sorts tasks by location.

No easy way to import/export tasks in a format compatible with other apps.

Used this app in the past, and just downloaded to give it another go. Definitely a good app and one that I'd recommend.

Very good Task app! Awesome!

URL is not a changelog

Just cannot get this to show my synchronised tasks a all

Terrible UI. Look elsewhere.

Google play store

Works with Zimbra

Works very well with our Nextcloud server. An important app when using your own Caldav server. Thanks for continuous development.

Good app, since the last update i keep getting all my old reminders daily ,even if completed. Usually the app works well. I don't like the design. But I can't find an alternative so I'll stick with this. I also don't like that it changes the order of my items to alphabetical, I sort mine in on my mac according to importance


App is working great. Lots of features. Not really eye candy yet. Synch to my NextCloud seemed to be not working, but I didn't have the tasks app enabled on my Cloud. Still after getting past that, the default "My Tasks" part of OpenTasks won't synch. Tried adding the list in cloud tasks, tried adding it to cloud calendar with no success. All tasks added to existing calendars from cloud work fine.

A simple task management app that integrates well with Nextcloud via another app, DAVdroid. Can't see recurring tasks anywhere in the app yet, but the features that are present work well.

It does what it says. All of my tasks are reccuring, so this falls short in that part, but I know the description says it's coming soon. Hopefully it's coming sooner than later.

Update: As this is one of my primary apps on Android, it's great to see that it has been open-sourced as promised. Also, the dates thing below has been worked out, and subtasks is behaving as desired and the UI is beautiful. And with the new "flick" motions, and working text search, I can finally say that my Android tasks PIM is better than the one I had on Palm. Works great with Radicale, BTW. Nice job, guys! ======================================================================================== Update: It seems tasks are laid out according to GMT, rather than local time, on the "Due" tab (Today, Tomorrow, Next Days, Someday). Due dates display correctly in editing and on the server. This makes it a bit difficult to see what you've entered for Tomorrow, as it appears as Today, etc. There's also some inconsistency when dealing with subtasks. It seems there may be two or more standards for specifying them: one way wherein the subtask is entered as a new line in the Description field, and another using a more formal specification. Otherwise a nice little app. Looking forward to paying a few bucks for it once the kinks are worked out.

Good app, but still, but a bit "raw". I need ability to sort tasks (manually or by priority/creation date/due date etc). I need dark interface theme. I need specific icons for task lists, it's good though that users can at least pick specific color for lists.

It has a problem remembering the due dates. You have to re-enter it several times to make it stick.

Essential for use with Smoothsync for Cloud Calendar app, which allows me to edit iCloud calendars. Has worked reliably in the background for me for years. Thanks!

Perfect for keeping track of college assignments and deadlines. I just love the task progress tab. Motivates me to work more!

This app is awesome except there is no way to change default color of the calendar or task. Also why I've to keep the app open in the background to get the reminders notifications.

Widget does not display tasks correctly

It's great, but I would like to see some more customize options. A dark theme would be nice.

Works fine with davdroid. Dont support subtasks hierarchy.

App dose not sync from the task and calender I created on hureder.

Tasks reoccurring?

Smart and works well.

Best app I found to share tasks with people who have Apple devices. Look forward to having the promised improvements deployed.

Nice app use it with NC but very slow development. Better put a price to have a motive for quicker development and features implementation.

I can't add/edit text with spaces in checklist. The cursor will jump to the first character when I press space.

Very nice user interface!

It's got a great-looking interface that doesn't look like a teenager’s MySpace page. The one problem it has is that it does not cache the tasks lists. My phone connection is intermittent and this app sometimes claims that I have no list to add tasks to.

Simple permissions and UI is great, very crisp. Does lose scroll position if you rotate your device, annoying on long lists. Would like to be able to drag to reorder lists in the "Displayed lists" settings page.

OwnCloud tasks client with synchronisation. Once the recurrence support is there, this will become my main task manager.

Great workaround to syncing iCloud reminders with my Android. Still waiting on widgets, recurring tasks, and alarms.

No. 1 app. But there Should be google sync facility also and there should be calander view

This has no valid need for access to contacts. Uninstalling.

Integrates great with my Nextcloud instance. My wife and I use this app nearly every day.

Fantastic app, gets the job done very well.

Contacts won't let me log into iCloud. Same pass email as Cloud Calendar!!!???

it's a good promise!

This app needs a sorting option for the lists.


Some of my lists have many entries. New items are arranged at the bottom. An intuitive approach would be the other way around. However: Try to add 3 new tasks to an existing list of 50, then arrange the new ones on top. No dark theme available. It is free and it seems to be the only app compatible with CalDAV tasks, so I gave 2 stars.

I love the simplicity of this app and use it with Nextcloud/Owncloud. Unfortunately I've got a bug since a while: in the task-detailpage, the font in the topmost colored container, blinks up for 10ms but then disappears.. Please could you fix this.. I highly depend on the "+1day"-button ;)

Together with DavDroid, this is the perfect task manager. Only one suggestion/request: it would be good to have an option to put tasks with no due date at the top rather than at the bottom. If I forget to add a due date, then I often don't realise as I don't see the task again.

EDIT 4/14/2016: The app has magically started working again. I'm bumping this up to three stars now as the app has "magically" started working again. I'll bump it up to four if it continues after 60 days. --------------- I LOVED it until it suddenly stopped syncing with iCloud... AND NO WARNING! For that reason alone, HORRIBLE UX!

This was a very promising app, but the code hadn't gotten a commit in over a year now, so i assume it's been abandoned. While it's usable, unless development picks up again I can't recommend it.

Nice app but if possible give facility to set task list like if i need 4-5 stages like as per my business i need to generate client then set stages like 1 praposal 2 receipt 3 policy 4 policy delivery and once i set it then it is always on all of my task then i have to give only task name stages will appeare autmatically

It works with another app "CalDAV-Sync" to flawlessly synchronize with iCloud Calendar & Task. Please keep on the development to add more features (e.g. recurring task, alarm time for each task).

This program works perfectly, it syncs with synology caldav server with Marten's caldav sync app, and is fully compatible with gnome evolution. It would be even better if there was another program that worked equally well with caldav/ical VJOURNAL entries then we could have full synchronization with contacts, tasks, and notes/memos/journals via carddav and caldav.

does exactly what i need it to do and respectful of my information. all the big name apps charge u for the app and then sell ur data after lulz, be smart like us!

This is a nice simple app for getting things done. One drawback is that it doesn't have subtasks. Otherwise, it's a great app.

Really good app, just wish it would sync with Google tasks but for free can't ask more, could add heaps more improvement which I'm sure will be added in time.

Best CalDav Task App. Missing only one thing. I don't use all fields, so it would be nice to hide fields when you edit a task.

Thanks for making this wonderful app free. May I ask, if it's possible to add the feature to duplicate a task like Evernote. Also the ability to attach documents and picture inside the task would be the pretty amazing and perfect. Thanks nonetheless.

The only thing I can tell that this app did was repeatedly pop up a message saying "Unfortunately, Open Tasks has stopped."

Scrambled my whole calendar input Thanx 4 restoring 3 days work lost.. GGGRRRRRRRRR. #@#@#!!&$#$$

Best and simplest task aparicio. Allows me to still share tasks with my gf. Really need that reoccurring feature though

Missing a critical option which is to add a recurring task (paying bills, exercising, etc.)

Just switched from iPhone to Blackberry Priv and a great app, thank you and well recommended. Currently works in a separate app from the native tasks and hoping the 2 will be able to sync in due course.

Works perfectly for me. All I need is a basic task app that sinks with the "To-dos" section of my Yahoo calendar. This does the trick splendidly, and has added functionality and customizations that may come in handy down the road.

The widget should display only one of my lists.. And I want to be able to switch between the lists

The app is simple and efficient, and the developer is very responsive to bug reports.

Good, but the UI is a bit primitive. Would love to see an upgrade that would improve the look and feel of the app.

A provisional 5 stars. The app as it stands is good but it really needs the recurring tasks completed to become a genuine 5 star app.

Great software. One feature needed for 5*: recurring tasks.

can't create any task

Very useful and with a smooth synch with icloud. It would be good to be able to sort lists order manually rather than alfabethacly.
