This means that every single calc is saved to the bar, and you can pick and choose inputs from the bar to save time. ### 3.1.0 — 2022-11-07 • After calc is finished, typing a number now clears the display and starts a new calc. • Cleaner layout and removed 00 • More in-depth tutorial / about app section • Cleaner updated in-app purchases section • Video ad's now display after set amount of usage in app vs at app start ### 3.0.1 — 2022-01-10 Small Bug Fixes - This really means I did not write a test to make sure the data persists on the app when you close it and re-open. How embarrassing. ### 3.0 — 2022-01-04 Updated the math formula! What's 1 + 1 + 1 x 0? If you thought it was 0... I'm sorry but the order of operations (PEMDA, Parenthesis, Exponent, Multiply & Divide from left to right and Add & Subtract from left to right) means we multiple 1 x 0, then at the result 0 to 1, then again add 1 and we get 2! The calculator was not smart enough previously to get this correct, but now it is much smarter! In order to show this change with the design, now the whole operation will show until you are ready to calculate. I also took the time to update the design, because I can't help myself. Let me know if you think it's an improvement. Updated to include IDFA Transparency Tracking, which lets users know how Google Admob users your phone's information to play advertisements. ### 2.0 — 2021-07-05 Big update! There were several bugs in the app that caused it to crash, not ideal and I fixed those. New UI with the latest update to SwiftUI. Added a positive, negative button. Pay to remove advertising is setup, get rid of those pesky ads. ## Apps similar to Adam's Calc | App | Rating | Price | Category | | --- | --- | --- | --- | | [Quatuorvigintuple Calc](https://appshunter.io/ios/app/quatuorvigintuple-calc/id6742525996) | — | Free | Utilities | | [Quinvigintuple Calc](https://appshunter.io/ios/app/quinvigintuple-calc/id6742526244) | — | Free | Utilities | | [Nonuple Calc](https://appshunter.io/ios/app/nonuple-calc/id6742040810) | — | Free | Utilities | | [Quintuple Calc](https://appshunter.io/ios/app/quintuple-calc/id6742364690) | — | Free | Utilities | | [Octodecuple Calc](https://appshunter.io/ios/app/octodecuple-calc/id6742386286) | — | Free | Utilities | | [Encouraging calculator](https://appshunter.io/ios/app/encouraging-calculator/id6502799928) | — | Free | Utilities | ## More apps by RD Concepts - [Dual up down timer](https://appshunter.io/ios/app/dual-up-down-timer/id1294165793) - [Edibly](https://appshunter.io/ios/app/edibly/id1303242056) - [Cipolla](https://appshunter.io/ios/app/cipolla/id1466418424) - [Engage Timer](https://appshunter.io/ios/app/engage-timer/id1470569685) - [NatureFM](https://appshunter.io/ios/app/naturefm/id1576891060) All apps by RD Concepts: https://appshunter.io/developer/1293498470 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
