Ratings and Reviews
The perfect calculator app
I like being able to see the numbers I enter and then the action taken and then the following number etc.
I also like that it shows previous calculations should you need to check them.
Lastly, the copy/paste feature couldn’t be simpler which has proven itself useful on many occasions. You can even email the tape of your calculations which is very handy!
One cannot review this app without giving it a big kudos for the minimalist yet powerful design. The user interface is simple and self-explanatory.
My only wish for this app would be a true black theme for those of us with OLED screens. It helps save battery and just looks cool. It’s such a small request, you can tell how perfect this app is!
Sounds stopped working after last update.
No sounds, no haptic feedback on iPhone 6s when using the calculator.
Done with Tapbots. Fan no more.
For context, I have been a fan and supported Paul and Mark since 2009. I bought all their *bot apps. Over the years, I continued to support them by buying every new version of Tweetbots, which happened on a yearly basis at one point. I was okay with this given there was new functionality and features with every new iteration. For whatever reason they decided to go with a different approach with Calcbot. I purchased this when it came out and had access to its full feature set. Recently, I noticed most of the features were no longer available and locked out. I contacted support and they told me I needed to pay to access the upper tier features—features I previously had. That doesn’t seem right to me. I gave them every chance to make this right but they didn’t. Now I’m speaking out, hence, the reason for this review.
