The developer responds to user input very quickly. I’ve tried loads of currency converters. This one is better than XE for various reasons. Very happy. **Developer response:** Thank you very much for your feedback. Please get in touch with us via X or Email, which will help us solve this problem.🙏 ### 5/5 — Un insdispensable *2025-02-10* Application couteau suisse indispensable. Il fonctionne rapidement et parfaitement l'interface est très agréable. Je recommande et je remercie le développeur. ### 3/5 — Old design was better *2025-02-09* The previous design was better. Currently, the currency display is more limited compared to before, where multiple currencies could be viewed simultaneously. The new layout, with its oversized elements, is less useful for displaying numbers in a calculator-style format. The previous version was a key factor in the program’s success. I hope you take this into consideration. **Developer response:** Thank you very much for your feedback. We already optimize it in version v3.3. ### 1/5 — Calculator is broken in iOS 18 *2024-11-22* Unfortunately there seems no way of contacting the developer. The currency calculator is broken in iOS 18. If I change from one currency to another and then try to subtract a number the calculator is producing an incorrect result. Will change my review back to five stars once this major bug is fixed. Thank you. **Developer response:** Thank you for your feedback. We have fixed the bugs you mentioned in the new version.🙏 ### 5/5 — We need volume convertor *2024-09-30* Converting volume is an important feature! We have liter, quart, fl oz, etc. Please also note that UK and US define them differently. It would be great to have the functionality! Thank you. Secondly, the round button is a little small and sometimes miss touching. Lastly, sometimes the display is buggy. The first item would be in the center. 谢谢开发者，五星支持！ **Developer response:** Thank you very much for your feedback. We have provided the volume converter in version v3.0. ### 1/5 — Calculator is broken in iOS 18 *2024-09-24* Unfortunately there seems no way of contacting the developer.
