    A very well made calculator that has more functions than what most people would need. I always install it after a fresh OS install.,

    This application is very good, because it calculates numbers. Not only it does calculate, but also provides you with a few converters. If you want to have more converters, use the NT converter app. Also, the dark mode is nice. But it has problems: 1. The date selection dialog is all black, leading to dates being unreadable (black on black) 2. When calculating very large numbers, it gives you values like 3.16129E15. Thanks for fixing bug #3!

  3. Alex x-avatar

    When using split screen to calculate while viewing another app the numbers are cut off and hard to read. For this reason I deleted and use my phone's regular calculator even though it lacks some of the minor features available here.

  4. Julkio S.-avatar

    It's great, but the top bar use too much space, maybe enlarge the calculation area

  5. jaynesh kumar-avatar

    Hi developer There is no calculate option in loan calculator. It doesn't calculate after you fill the relevant details. You need to fix this.. I'll update my rating after this is fixed..

  6. Nat n Rob-avatar

    Exceptional calculator. Beautifully made, extremely functional. Dates, times, sci, lian, everthing. Thank you.

  7. Chris Olonzo-avatar

    Great for simple "get me a calculator" needs as well as for unit conversion and advanced scientific calculator needs.

  8. TheTAMAS Gautam-avatar

    TheTAMAS Gautam


    Great app. Suggestion:give an option for Indian numeral system as well. We separate numbers in this way- 12,34,56,789

  9. Atchup Boulevard-avatar

    Atchup Boulevard


    All in one place a calculator that's everything you need. Thanks for this dev. Highly recommend xD

  10. maths madira-avatar

    Unable to use trigonometric inverse function. Not user friendly.

  11. John Williams-avatar

    Please update to allow feet & inches conversions. Cracking calculator, radix mode is great that it shows all conversions.

  12. I2 K4-avatar

    Very elegant multipurpose tool, dark theme is AMOLED friendly. Thanks.

  13. Cycad Sonic-avatar

    Time can be improved. I can type hour + minute + second.

  14. Ramanan T-avatar

    Unit converter and calculators in one place. Good job

  15. Pete Knoll-avatar

    Good calculator.....it'd be great if it had a widget...

  16. Biswajit Nayak-avatar

    Missing discount feature

  17. Troy Dalton-avatar

    I have a dozen Android calculators just from searching for the right one for me. There are two I use on a regular basis, depending on what I'm doing. I didn't think this one would be any different than the great masses of existing calculators, but I was pleasantly surprised! Though the UI could use a major facelift, some of the displays present results in a great and efficient way. I've added NT Calculator to my daily use calculator list.

  18. Baczo Zsolt-avatar

    Nice, clean and feature rich, but I would like to be able to edit the formula (without the need to go back with the delete button). E.g. I type 25x22+11+1, and I want to edit it to 26x22+11+1, now I have to delete everything except the first 2, to be able to edit it, and then I need to type back x22+11+1 again. Not very useful in these situations. Also, showing results live (without the need to hit the = button) would be better.

  19. Chris Smith-avatar

    Nice roundup of functions but lacks customization found in the free and ad-free MobiCalc. .... This app needs theming support and sound options on key press to get 5th star. esp the theming to allow for dark background. Even Google has finally seen the light when it comes to dark backgrounds. TY tho to devs for making this app free! 👍

  20. Mislav Komerički-avatar

    Mislav Komerički


    Nice theming, but usability could be better. There is no heptic feedback while typing. "Backspace" button is awkwardly placed at the bottom right corner (instead of upper right) in standard node. Then the same button (without obvious reason) changes position depending on the mode one is using. EDIT: tried using it for a while. I can't get used to it. *uninstall*

  21. Gary Olsen-avatar

    Date Calculator is Wrong! Doesn't take into account leap years. Doesn't calculate days correctly. for example, 22nd March 2019 to 29th Feb 2016 (the first last leap year) is 1117 days or 3 years 22 days. the calc tells me 3 years 24 days. Switching to add/subtract, of I then subtract 3 years 22 days gives me 28th Feb when it should be 29th. 3 years 21 days then gives me 1st March - there is no 29th Feb. Unreliable. *** Sorry bud, still the same problem ***

  22. Mille Guust-avatar

    Great idea but....Time calculator is way off with uneven hour and minute devision. Try 7h dev by 2 equal 3???? Should go to next rank and show 3h30m ....Please fix

  23. Alan Squire-avatar

    It's awkward that the RAD/DEG button is also the "Inverse" button.

  24. Raymund Lanit-avatar

    There is something wrong. Using the standard calculator, testing it with dividing 5-digit numbers by single number, the answers are wrong. Please check. Otherwise, the app works well. Doesn't crash or anything.

  25. A Google user-avatar

    Great calculator/simple conversion calculator. Not something to replace an actual conversion calculator app (it doesn't have all of the conversions of a conversion app), but would definitely recommend to someone that needs a calculator for class or for everyday calculations.

  26. C G-avatar

    This app is worth the asking price. Easy to use ... but now that it's on special.. go find the donate button in the upper right corner of app and give him the 99 cents. What a steal for an app that's fully secure!!! Beautiful layout, and even a dark theme! This app exceeds my needs but nice to know Sooooooo many choices! 🍻 😊😘.

  27. Jack Rogers-avatar

    Hi, Thanks for replying. The current dark theme is black in color. It's good for amoled screens but becomes too dark for day to day use. Please add a dark grey dark theme option like many other apps example - Solid Explorer, Nova Launcher etc. These apps have a Dark Grey Dark Theme. Thanks.

  28. Gamer Bass-avatar

    Its good.lots of feature..money worth it

  29. m 2-avatar

    Got this when it was free. It's a cute little calculator if you can get it for a good price - which $3.00 is. It seems excessive at first but it was made by a small developer, so all support should be given.

  30. Hoang 91-avatar

    It used to be good. Now I can't even input numbers the right way, and those +-*/ are also "invalid input". For example "355"; click 3, then 5, then 5 and it turns out just "5".

  31. Walter Zobernig-avatar

    Walter Zobernig


    Good App with different modes and convertors. But I would like to see the actual temporary result before pressing enter (for a follow up of what I enter) and an optional dark theme to save battery would be nice.

  32. Anthony Merritt-avatar

    Anthony Merritt


    I like this app and it has a lot of potential as a unit converter. The US volume conversions are incorrect: 8 fluid ounces = 1 cup, 2 cups = 1 pint, 4 quarts = 1 gallon, etc.

  33. Tong T.-avatar

    Nice clean app. Need a better way of picking date on date converter though. If you need to calculate 2 dates that are far apart and you scroll 1 month at a time, that's a pain.

  34. Prizm-avatar

    This calc. is great and has served me well out about and during my school times, but i think something is missing such as a statistics calculator which creates a table and allows you to get standard deviatoon and the others

  35. Fearless Ferdous-avatar

    Fearless Ferdous


    Hello, i like this calculator. But it needs some improvement. 1) need some theme (ex- black bg & green font combo, black blue combo) 2) let us remove specific history from history list.

  36. Suzanne-avatar

    Love this so far. Simple, accessible, and clean. Thanks for adding new history features enabling us to save, manually delete, or clear on exit.Thanks for a functional app!

  37. Adam Peek-avatar

    This app really raised the bar. It's the ideal replacement calculator and so much more, yet still appealing to the minimalist.

  38. Stanton McCandlish-avatar

    Stanton McCandlish


    My go-to calc app for most purposes. Been using it for years, on every phone. One of the few apps I've been willing to actually pay for and not regretted it.

  39. Stanimir Števkov-avatar

    Stanimir Števkov


    It's great app but I can't change language. No matter what language I select nothing happens on my tablet. On the phone I can choose language.

  40. Shannon Bowles-avatar

    This is the best calculator I have used. It is like having a seperate calculator with you at all times. Native calculators are so limited.

  41. nat lider-avatar

    Have been searching for an easy to use calc that includes different units of measurements; this app ticked all the boxes! Easy to use conversion for feet/metres and time calc between dates. Very happy :)

  42. A Google user-avatar

    Excellent features and Dark Theme is almost great. Just change the function keys (+,-, etc.) to a brighter color.

  43. A Google user-avatar

    A lot better than the phone's native app, stable, and includes a converter. No ads! +1 star for updates.

  44. Richard Wong-avatar

    The best there is. If it can default with the last units used, like pounds and kilos for weight, it would be excellent

  45. Ανδρεα Μπαρε-avatar

    Ανδρεα Μπαρε


    Very good app full of features, but if you can add tax calculator it would be great.

  46. Eric Feinstein-avatar

    Solid, but could use a few more convenient calculators (tip Calc, for instance)

  47. DJ Kavas-avatar

    Hi Dev, first of all thank for for this app. please add a manually input; year or all of ones, for Date -> Difference between dates.

  48. Brett Sweet-avatar

    Great caclulator app. Many functions! Conversions for length, weight, volume, etc!

  49. A Google user-avatar

    A very well coded app. Constant development based on user feedback is great.

  50. Sheldon Dedek-avatar

    Put in same equation as depicted in screenshot. -(5x9)-9 and where developer gets -54 my result is -45.09. message sent to dev with screenshot.

  51. Tomás Roda-avatar

    Very complete app, lot of options and very nice UI

  52. Jonny S-avatar

    Great app very well made. Suggestion for an future update add in a tip calculator

  53. Milind Bajekal-avatar

    Loved it! All useful converters and calculators in one app.

  54. Jakkie Enslin-avatar

    Awesome app had an issue for a day after update and the fixed it.

  55. Demetrios Pyrros-avatar

    Demetrios Pyrros


    Time calculator is wrong! 3h6m3s divided by 2 does not equal to 1h3m1s but this is the result I get! How can you publish such an app and ask for money as well?

  56. Matt Lee-avatar

    Does exactly what it says and is brilliant. I bought it in the sale but it is worth the money

  57. Mr. A-avatar

    Good Alternative for Miui calculator app as this takes low space & has all functions available

  58. Kyle Drayton-avatar

    Needs material design and a dark theme, but is great functionally.

  59. Tristan Stanic-avatar

    Nice GUI, like very much the built-in unit converter feature.

  60. Glenn Palfrey-avatar

    So much more than the basic calculators. Donation sent but no pressure to do that 🙂

  61. Brian Wibawa-avatar

    Good calculator. Would give a 5 star if you include/allow degrees minutes seconds

  62. Roman Catholic-avatar

    really really useful and easy to use congrats for making such a reliable calculator!

  63. Mohit B-avatar

  68. Tere Fredericks-avatar

    Tere Fredericks


    I work in an area where there are due dates, for example, within 30 days after something else happens. Rather than me counting between dates with my fingers, this is the BEST.

  69. joe aldo-avatar

    please make number and symbols more bold in dark mode, n for symbols i think more better if the color more brighter

  70. amir-avatar

    i really enjoy that, stylish, nice and useful. thanks for this.

  71. Paul Vandeyar-avatar

  73. Flow Peruna-avatar

    Well the calculator is great but if you use sin-1, cos-1 or tan-1 the calculator only gives the normal (sin) or (cos) or (tan)

    NeAt and Clean, Free Too.. Best Calculator App Available 😊..

  75. Mario Láser-avatar

    please add a dark theme that does not contain blue as it degrades the amoled screens faster and blue light is bad for sleep

  76. Nishan Pradhan-avatar

    One of the most useful app I've used for calculation
