Habit trackers that work without an account

An account is friction at the exact moment you were finally motivated to start, and it is a record of you in somebody’s database for as long as they keep it. For a tracker that stores everything on your own phone, neither of those buys you anything.

Quite a few apps advertise “no account required” and then require one for anything past the first screen: sync needs an account, backup needs an account, the widget needs an account. That is not what the phrase means to a reader, and the gap between the App Store copy and the second launch is where the frustration lives.

There are three honest shapes. Fully local, where there is no server at all and backup means an export. iCloud backed, where sync uses the user’s own iCloud and the developer never sees the data or a user record. And key based anonymous sync, where a random device key stands in for an account and there is nothing linking it to a person.

This page lists the current iOS trackers in each of those shapes, explains how to verify the claim yourself in about two minutes without any tools, and covers the one genuine downside of every accountless design: nobody can help you recover data if you lose every device.

Outline

Status: outline. The introduction above is finished copy. Everything below is the section plan for the full draft, targeted at about 1 300 words.

1. What an account actually buys. For the user, and for the developer.
2. Three accountless shapes. Local only, iCloud backed, and key based sync.
3. The claim and the second launch. Where “no account required” quietly stops being true.
4. Verifying it yourself. Two minutes, no tools, in aeroplane mode.
5. The current list. iOS trackers by shape, with what each gives up.
6. The downside. No recovery, and how to cover for it with exports.
