Cats Cats Calculator
Read full descriptionHide full description
When you actually try using this calculator, you'll find that the cat gets in the way, making it difficult to perform calculations. Although it has some drawbacks, such as the buttons being hard to tap and the calculation results being hard to see, it's an app that can be enjoyed and shared with friends. If you can't tap the button and accidentally tap the cat, the cat will meow.

Verdict
The clearest difference is in-app purchases: Cats Cats Calculator at none against Quick Diary's 1. Quick Diary's advantage is ads (none vs shown) and update cadence (every 5 weeks vs every 9 months). On price and device support there is nothing between them.
