HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (55 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★Jan 27, 2026

I have been using this app for years because I love how cute it is, but the amount of unclosable ads (needs to force close app) now makes it so irritating to use. I'll continue to use it for 2026 as I already inputted my whole year's schedule but will be looking for a different app for 2027.

★★★★★Feb 17, 2024

its a good replacement for pettato calendar but the interfce i a little akward And it doesn't have any widgets which makes it easier to look at a first glance.

★★★★★Aug 25, 2023

this is my go to for every matters

★★★★★Nov 18, 2022

The app is nice but I refuse to use or score highly any app that uses forced full screen ads. They're obtrusive af.

★★★★★May 3, 2022

Cute stamps and able to write in notes on stamps. It's my go to calendar.

★★★★★Jul 19, 2021
