### 5/5 — Perfect for calculating my work time card!

*2026-04-19*

This is exactly what I needed when adding up my time card from work. It allows you to put in your pay rate and will automatically show the total time and the total pay as you go. Very customizable with lots of themes. I’m left-handed and I was pleasantly surprised to find that you can even set which side of the screen you want the keypad to be when in landscape mode. This is probably the best time calculator on the App Store imo!
