I can't imagine how this app got approved. ## Most praised reviews (10 highest-rated) ### 5/5 — Best Apple Watch calculator!! *2020-03-16, version 3.5* I have went thru about 6 calculators for my watch and this is the best. First, it is very simple. If I want complex I use my iPhone. Next, the buttons are about as big as possible. But the stoke of genius was adding a tape of the calculation along the top so you can be sure you put in the right numbers. ### 5/5 — Perfect for iWatch *2018-12-17, version 3.4.8* Very simple calculator with large numbers makes it perfect for my new iPhone. ### 5/5 — Fantastic. *2018-10-12, version 3.4.7* I’ve looked at a ton of these apps .. this is the best layout for me. All the basic functions on one screen without having to go back and forth ... also handy is keeping the function key a different color after it’s depressed. The only thing that would make it a bit better would be a horizontal tape at the top. ### 5/5 — Everywhere *2018-07-11, version 3.4.5* I use it in my phone and pad ### 5/5 — Works Great *2017-11-27, version 3.4.5* Works great for me. Just a calculator. Just what I needed. ### 5/5 — Worked perfect & Easy *2017-10-28, version 3.3.1* Installed no problem, super easy and simple, I have the latest os 4.0.1 ### 5/5 — Terrible!!! Maybe not!! *2017-06-22, version 2.0* Well I just wasted $.99!!!!! On second thought, and after a few minutes this works great I may update this as we go along, so far I would recommend it! ### 4/5 — Works fine *2018-10-23, version 3.4.8* I just installed this app and its working fine on both my phone and watch as of 10/23/18. ### 3/5 — So much better apps that are free *2016-11-09, version 2.0* Title says it all. This was a waist of a buck. It is not put together well. Check out calculator% no adds and on the Apple Watch there is haptic feedback. ### 3/5 — Needs glance view *2015-10-11, version 2.0* Works fine as app but would like to add to Glances. Did not see an option to add. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
