Easy to use & simple

Google Play review · September 2018

Updates that started with a review

Reviews shape what gets built next. What these two asked for is now in the app.

it's easy and nice to use. would like to suggest though to have an option if the first day of the week would be sunday or monday. :))

Google Play review · August 2026

Lovee the app, it's exactly how I want, but just a small issue that I've personally come across is that I can't choose to make the week start on Sunday (the convention in my country). I hope it's added, but other than that it's a lovely app.
