Why we built Singletick

I got tired of habit-tracker apps wanting my email, my contacts, and my location to track whether I drank water.

Singletick is the answer to a small but persistent frustration: every “productivity” app on the App Store wants to know things about you that have nothing to do with the feature you opened it for. A habit tracker shouldn’t need an account. A notes app shouldn’t ship a tracker SDK. A focus timer shouldn’t sync analytics to a cloud you’ve never heard of.

So I built one app that does all of it — habits, todos, notes, pledges, mood, focus — and treats your data like the personal, encrypted-by-default thing it actually is.

The privacy charter, in plain English

1. Your content never leaves your phone. Every entry is encrypted on your device before it touches storage, with a key derived from a passphrase only you know.

2. Backup is yours, not ours. Encrypted blobs go to your own Google Drive or iCloud private container. Even your cloud provider sees only opaque ciphertext.

3. No accounts. No tracking IDs. No email capture. Singletick has no sign-up. The only thing we know is that the app exists, via anonymous analytics events that contain no content.

4. Pro is paid, not extracted. The Pro tier is a normal subscription handled by the App Store / Play Store. We never see your billing identity. There are no upsells inside features you already paid for.

Why one app instead of seven

The real reason productivity apps fragment is incentive: each app wants to be the one that hooks you. So you end up with three habit trackers, two notes apps, a pomodoro timer that pings a server, and six different sets of tracking pixels following you around the internet.

Singletick is the inverse bet. One app, one private box, one relationship. Free tier covers the basics with no usage caps. Pro unlocks the things that need real engineering effort — encrypted backup, web companion, locked notes, advanced insights, widgets.

If you’ve ever quit a habit tracker because the third popup asking for your email finally got under your skin, this app is for you.

What’s next

The mobile app is shipping for Android first, with iOS following shortly after. The browser companion (a laptop surface that pairs with your phone over a 6-digit code) is in active development.
