Apologies if this is uncouth, but if anyone wants the opposite of this product, check out Pixelist on the App Store: it’s a 100% free and private, extremely minimalist habit tracker. I’m terrible at marketing (my Show HN had zero response) but it’s had a growing organic user base that seems to love it.

Tickmate was something I used for a long time, but Google says it's too old for my Android. =(
