The app is clean and the linking feature is promising. However, the input logic is currently too rigid for dynamic work. The automatic parentheses (e.g., 1/2+3 becoming ((1/2)+3)) cannot be moved or deleted, making mid-calculation edits very difficult. Without an undo feature, mistakes require too much manual correction. This could be a 5-star app with more flexible editing and standard math input rules. **Developer response:** Thank you for your support and feedback. Taking note of your feedback. Thanks! Hi again, version 1.17 has now undo/redo and buttons to move the cursor left and right. Hope you like the new features....! ### 3/5 — It has potential to be great *2025-12-29, version 1.16* This calculator definitely has potential to be great pumped. Unfortunately, you cannot set brackets. You can’t even change brackets. Therefore, the calculator is unusable for a lot of calculations. If this would be changed Caldy has the potential to be great. ### 5/5 — Cool and now with AC button! *2025-01-27* I use to use tydlig a lot, but it’s not being updated anymore, Caly is a good replacement! The developer just added a AC button!!! Thank you!!! Makes it easier to use!!!! ### 5/5 — Update reset button done *2025-01-27* Excellent app. I love it ### 5/5 — Cool *2024-11-28* I use to use tydlig a lot, but it’s not being updated anymore, Caly is a good replacement! Only needs an all clear button and then it’s perfect! ### 1/5 — Not working on iOS 18.2 (22C5131e) *2024-11-17* Can’t find a way to contact support. Calculator not working on iOS 18.2 (22C5131e), just get a black screen past the documents view. **Developer response:** Hi again, version 1.17 has now undo/redo and buttons to move the cursor left and right. Hope you like the new features....! (Hi, sorry about that, an update has been pushed. Version 1.12 should be working on iOS 18. Thanks. ☺️ ) ### 4/5 — Nice with desire for improvements *2024-08-08, version 1.11* Most wanted feature is a AC all clear button. ## Frequently asked questions about Caldy ### What is Caldy's main advantage over a standard calculator?
