Day31 compared

Why we publish these pages

If you are counting days for a visa limit or a tax-residency test, the tracker you pick matters — you will live with it for years, and you will trust it in front of a border officer or a tax auditor. So we compared Day31 against the apps you are most likely to find next to us in a search.

Our ground rules: every claim about a competitor comes from that competitor's own public website or store listing, linked and dated (checked August 2026), so you can verify it yourself. We say plainly where each one is stronger than Day31. And we never quote our own prices here — the App Store listing is the source of truth for what Day31 costs.

If you maintain one of these products and we got something wrong or stale, tell us and we will fix it.

The one-line version

Most trackers in this category run on an account and a server. Day31 runs on your iPhone: no account, no sign-up, location data never leaves the device, and it keeps counting in airplane mode. It can also rebuild years of past travel from your photo library's metadata in seconds — the record you forgot to keep, recovered. If those two things matter to you, Day31 is probably the right choice; if they don't, one of the apps above may serve you better, and each comparison page says so.
