Sinceify is a free "days since" counter and habit streak tracker. Count how long you've kept a good habit, how long since you quit a bad one, or how long since any life event — sobriety, a new job, your last workout, anything worth remembering.
It's private by design: your counters live on your device, not on someone else's server. Optionally sign in with Google to sync them to a hidden app folder in your own Google Drive — Sinceify can never see your other files.
Sinceify is a free web app that counts the time since anything — how long you have kept a habit streak, how long since you quit something, or how long since a life event. Create a counter and it tracks the days, hours, and minutes automatically.

Yes. Sinceify is an installable progressive web app (PWA). Once loaded, it works fully offline and can be added to your phone's home screen like a native app.
Sinceify combines habit streaks (building good habits or quitting bad ones) with milestone counters in one place, keeps a full reset history with notes and statistics, and is private by design — no ads, no account required, and your data never touches a third-party server.
