Perfect app, before the June update

Not sure why the decision was made to redesign the interface. This has been my preferred calculation app for YEARS. The update is slower reaction time, and miss the clean boxes. The design is annoying now. Looking for a new calc app to replace (unless you can bring back the original)

Response from developer

Hi Thomas, Thanks for your review and sorry you're having performance issues. The next release should vastly improve that so we hope you keep an eye out for an update! We are submitting shortly. Thanks

Can we go back? I don’t like change.

I also do not like the update. I don’t like the new look, and was much happier with everything how it was.

Update not for me

I loved this calculator, but the update erased my most recent data, which sucked, and I find it really unintuitive and difficult to use. For example, pressing the calculator keys suddenly requires a lot of effort. This was an easy app that I could count on. I’m sure the update fixed problems for lots of people, but for me it’s just caused problems.

Response from developer

Hi there, Sorry to hear the update is not working well for you - our goal is to make the best fastest calculator out there! An upcoming update will address those performance issues so keep an eye out for an update. Regarding your history take a look and see if you have your History set to be Above the keypad, behind it, or even turned off. It's quite likely it's still there, just less obvious. If that doesn't work for you please reach out directly and we can help! Cheers

Amazing

This has been my favorite calculator app for a long time. I was so upset when development stopped (no that it needed new features to be great). I was concerned that OS upgraded would make the app unusable. I was so surprised to see this app suddenly get an update after a long time. I can’t believe how good the new improvements have been.

感谢开发者开发出来这么好用的 app,帮助我日常提高效率

Absolutely love this calculator. It turns a simple everyday tool into something much more powerful and enjoyable to use. Being able to edit expressions, revisit previous calculations, and get results instantly makes a huge difference compared with traditional calculators.
Thank you to the developer for creating such a clean, elegant, and practical app. It is rare to find an app that is both simple and thoughtfully designed. This is exactly the kind of tool that quietly improves your daily workflow.
