If you haven't used it in the past few years, it's worth noting that they really stepped up the gamification. I was shocked when I logged in to it recently after not using it since... maybe 2018? and every action in the app is accompanied by 10 animations, sound effects, "share" buttons, etc. It also now "randomly" gives you streak freezes. I've gotten 3 over the course of my current 100 day streak without spending any of the currency.
I've been on it for less than 6 months (151 streak), so it's always been like this for me. And I definitely had to "pay" for all my freezes after the initial 2.
