What's New in Extinct
1.1.5
July 12, 2026
Clearer streak. Your Home streak now reads as a consistency streak — the days you've taken your dose or logged activity — instead of an "alcohol-free day" count. It never claimed to track abstinence under the hood, so we've made the label say what it actually measures. Your alcohol-free days still live on the Dashboard, calculated from the days you logged drinks.
