I applaud your resistance to moving to a subscription model (typically an instant cancellation for me), though I think there are exchange rate APIs that that remain uncapped and free (though I haven’t researched in a while). But currency conversion remains a “nice-to-have” improvement, and its lack doesn’t really detract from the value of this tool. Thanks for your attention to my requests! Original: Conversion apps are a dime a dozen on the App Store. I really like the result display on this one. Updating all appropriate target units simultaneously gets my answer quickly with fewer taps and swipes. Having said that, more tap reduction is better, and there a few tweaks that can improve the efficiency. 1) Get me to my favorites faster. Either top load the favorites in the home tab or start on the favorites tab. 2) Don’t preload the entry field with “1” (or preselect it so it’s immediately replaced by my first input). I dislike having to remember to backspace first. Some nice things to have: Reorder the categories (you’d have to reconcile this with favorite top-loading if implemented). Add currency conversion. Yes, I realize this is difficult because there are too many target units to display all of them on the result array, so you’d have to allow us to choose the target currencies we want, and you’d have to fetch the current conversion rates. But it would be nice! **Developer response:** Thanks so much for the detailed feedback—I really appreciate it! I’ve just released v1.7 with several improvements based on your suggestions: 1) Customizable Tabs: In Settings, you can now choose your default start tab and rearrange the tab order. 2) Keypad Persistence: I've added a toggle in Settings—if you turn it off, the input will always start clean every time you enter a unit detail screen. 3) Category Reordering: You can now also reorder your categories directly within the Settings menu. Regarding currency conversion: Real-time rates require an external API with ongoing costs, which would likely require a move to a subscription model. I’m holding off for now to keep things simple, but it’s definitely on my list to revisit. Please update and let me know what you think! If anything still feels clunky, I’m always here to listen. ### 5/5 — Standout feature *2026-01-23* Conversion apps are a dime a dozen on the App Store. I really like the result display on this one.
