    I used to love this app! However it is not working on Android 10 on my Pixel 4XL. Please, for all things holy and just, fix my App!!!! 😁 Edit: 3/9/20 The app is working again. Thank you!!

  2. George A-avatar

    Very useful, and as far as Ive noticed these tools are exactly as precise and accurate as I've ever needed!

    A great tool set for anyone's phone! Very good value, and well put together.

  4. Lonny Eachus-avatar

    I adopted Smart Tools early. It has served me well. Great set of tools, well worth the paid version.

  5. Isaac Cuevas-avatar

    I'm been using this app since 2013 And I'm still using it. If that doesn't mean something, I can't say anything else. It is very smooth and easy to use. I highly recommend it.

    Fun & useful tools.

  9. Steven TS Lam-avatar

    Very useful for miscellaneous purposes

  10. A Roman-avatar

    Awesome product with so msmy features

  11. Mike Barnes-avatar

    Useful when you least expect it.

  12. Tim Weller-avatar

    Brilliant, so many uses!

  13. Karen 1-avatar

    Magnifying glass w/light is the tool I use most, it is always there to assist my vision needs. I have measured many items, converted weights & lengths. I have yet to have need of Distance or Sound. This the third(3 or 4) Samsung phone I had Smart Tools on. I have also loaned my phone to friends to take advantage of the Smart Tools, then encouraged them to Download to use when my is not available. Thank you Smart Tools!

  14. Simon Kidd-avatar

    Great tool for work

  15. SpEd-avatar

    I've been using the apps in this bundle for a couple of years, and I've found them very useful in many situations. This company also has an app called Unit Converter that I use far more often. The thing about these apps, is they just plain work. Nothing extra, no fluff, just a bunch of useful tools all gathered together in one app.

  16. Brandon S-avatar

    So... I decided to test the sound meter against my actual decibel meter and it was disappointing. Shooting a 22 rifle unsupressed is usually around 140 decibels like my store bought meter was showing. The apps meter only showed it at 88db. When I tried it suppressed my db meter showed 115-120db. Your app showed 75, this is clearly not correct nor in line with any study done on db levels from various things including firearms. Could it be my phone mic lowering the noise.. yes but not sure it is.

  17. Rick Ibbott-avatar

    I've been using this for years. Handy for those random moments you need to convert, measure or even level something.

  18. Kathleen Kelly-avatar

    I LOVE this app and find it useful for a number of daily tasks. It's my "pocket microscope" instead of having to look for a magnifying glass - I also very much appreciate and frequently use the metal detector. I could go on & on. It is by far, my favorite app and I've been using smart phones back when they were "PDA's, then Pocket PC's. Tech support is friendly and accessible if it's ever necessary to consult with them. Smart tools earned their 5 stars. I highly recommend this app.

  19. Tysum Gaming-avatar

    Love the flashlight, magnifying glass and the mirror because I use them the most! The other things are great too! Just don't use them as much! The app works well!!!

  20. Rafa El-avatar

    This app has been excellent value for money. The number of tools I get, and the quality and reliability of those tools, are just amazing. Is there room for improvement? Of course! That's true for anything. But do you get value for the small amount of money you spend? Absolutely. And that's not necessarily true for all apps. One user commented about 1 kB being equal to 1024 bytes. Well, that is not correct. This app is correct because 1kb = 1000 bytes (1KB = 1024). Different capitalization.

  21. Kitti Ehrisman-avatar

    You want to convert bytes, kilobytes, megabytes, gigabytes and terabytes? Me too. Can't with this app. No way to add what you need, or takeaway what you don't. Mebibytes, I'm looking at you. You can convert mebibytes but not megabytes. I've never heard of the former, but use the latter frequently. Just me? Dunno. Built-in flashlight is nice. Would you like it to strobe or blink SOS? The developer has responded he doesn't want to overly complicate things. Nice app, missing a few obvious tricks.

  22. Steve Latsis-avatar

    This was a great app tool set when I first downloaded it on my Galaxy S6. However, since I upgraded to an S8 and recently to an S9, the camera/lens feature no longer works/is disabled and I can't find any setting to restore it. Makes the magnifier and other tools kind of useless. There is no obvious setting to grant this app camera permission--please advise. The app installed with all others when I upgraded my phone.

  23. Clive Benjamin-avatar

    Brilliant, use the magnifying lens all of the time, and others occasionally, but so useful having it available whenever I need it.

  24. A Google user-avatar

    Mostly does what it promises. Note that the Distance tool assumes that the target and the user are on the same ground level; distance won't be accurate otherwise. And its Area function measures the rectangle defined by the earlier-measured distance and width: I thought is would measure the rectangle defined by the earlier-measured width and height. It should be able to do either. The description says that it isn't compatible with my Galaxy J series phone, but it does work, including the compass.

  25. SaberRusty-avatar

    Currently having trouble with noisey neighbours and my dad suggested i try a noise meter, then remembered he had gotten this app from somewher. I'm only using the sound meter really and £2.70 isn't much for no ads and a few more features than the free condensed version. Hopefully I can get some good readings :D

  26. David Stein-avatar

    Still indispensible (and routinely updated) after all these years! There's nothing I can really say that hasn't been said many times over. It's an outstanding app that's one of the first to get installed when I get a new phone.

  27. Scott-avatar

    I thought there'd be more to it than what there was. I couldn't seem to get the distance measured to work worth a damn but everything worked well.

  28. maher shtat-avatar

    Great...and one of those must have applications

  29. Mark Hammack-avatar

    This app is incredible for a person who is hungry for more knowledge in the physical statistical sense.

  30. Ron Taylor-avatar

    Arguably the most decent mix of useful measure-type tools out there for the small screen 'droid platform. So gofer it, just don't expect metrology level accuracies, it's on a pocket phone after all. 😎

    Third is one of my favourite and longest standing apps. I particularly love the magnifier and camera. But it is packed full of useful features for everyday life. Check out out

  32. Asfaloth 1859-avatar

    Good app, works fine and no bugs so far. The interface looks a bit dated, it would be nice if the developers change the aesthetics and make the app look more modern and elegant.

  33. Andre Bennett-avatar

    Love it. So far so good. Great variety of conversion options. the only thing i cannot get working is calculating real height/distance using the camera. Either way, keep up the good work.

  34. john a. gorman-avatar

    I bought this ages ago. I still use it often. It's so handy! Love the sliding ruler. The plumb level with camera is fantastic. So many goodies.

  35. Eric Cooper-avatar

    I've had this on all my phones for a million years and it always works flawlessly. The old school look of the app is part of its charm. And it's so easy to use and useful. I'll never delete this one. :-)

  36. Georgia Bosse-avatar

    This app has several useful tools which are easy to use and seem to be accurate. I especially like the level and the directional compass.

  37. Eugene Buhr-avatar

    I haven't paid for many apps. Of the ones i have this is the best. I use it a lot, and its fun too. Developer is quick to answer questions.

  38. Shirlene Ward-avatar

    Very useful, especially the lights and mirror. The compass is hard to calibrate, unfortunately. Definitely worth getting.

  39. Lovisa Bylund-avatar

    I love this app! Many usefull tools that actualy works. Although it is the converter I use the most.

  40. Jack in Canada-avatar

    This app contains several ''I wonder" type features to answer such things as 'how loud is she?' 'how tall is that building? or 'is the table level?'

  41. Patrick Deaton-avatar

    I purchased this app long ago and it just keeps getting better and better. The developer is awesome and I use the app almost everyday. Thank you for creating such and awesome app

  42. Greg Lafrenz-avatar

    Very useful suite of tools. Probably my most frequent use is converting measurements, typically for cooking. complete and powerful set of tools.

  43. Brett Mathers-avatar

    great app, use the camera microscope all the time when your eye sight or glasses are not up to the task.

  44. Bart Duineveld-avatar

    One of the first Android apps I bought (for my HTC Desire) and still gets updates, very good!

  45. Matthew Lawson-avatar

    Provides quick, intuitive, customizable acess to tools that take advantage of the sensors on your phone. Very useful.

  46. Kyle Murakami-avatar

    Good app. Well made. User friendly. Kind of long in the tooth though. Wish the developer would create some new tools or features for it.

  47. Joe Mettee-avatar

    Great set of tools. Don't leave home without it. Come to thing, I use it at home even more! Get it.

  48. Subramaniam Neelakantan-avatar

    loved all features. using the widget for all these features. works fine. very happy.

  49. ADDY-avatar

    Samsung s9.. The mirror is blurry. I think your app is not making use of the camera's auto focus..

  50. victor gonzalez-avatar

    victor gonzalez


    I use this app for a lot of things as a Maintenance Mechanic... Very helpful for fabricating....getting screen shots of angles of machines for guard making and such....

  51. Jon Jackson-avatar

    Very good app and the pro version is worth it. What I'd change :Use green or yellow for the level indicator at level instead of red

  52. Pete Killey-avatar

    A great NONINTRUSIVE app. Just what you need when you need it.

  53. Kevin Lausen-avatar

    i used it the other day to find electrical amperage for output on a USB charger, and it worked great.

  54. David Chan-avatar

    Useful once in a blue moon. Reliable app though where really needed and you have no data connection.

  55. Wil Langford-avatar

    App requires internet access to run. Why? I was bored on a plane and wanted to play with the sensors on my phone, but the app refused to start.

  56. Eric Neuforth-avatar

    I use it at work all the time. I work in a mine where there is no internet so it works every where.

  57. John Mullins-avatar

    I wind up using it when it's too inconvenient to go find conventional tools & these work great.

  58. Sandro Vicente-avatar

    Amazing app! Everything I was looking for!

  59. A Google user-avatar

    Super cool, bought it for the level, LOVE it for the the magnifying & mirror features!
