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.

The best Calculator app

This is one of those apps that’s so good, Apple should’ve done this. The longstanding ability to use brackets to do longer calculations all at once was what enamoured me to this app for years, but now with the swipe gestures for quick access to useful functions has made this the perfect calculator app. There’s really nothing else you need in an app like this and I’d recommend it to everyone.

Heck, I’d even pay for this app, so I don’t know if there’s a better endorsement than that.
