The record

Every check-in adds to your record.

A single mood is enough, and Save stays explicit. Days without entries stay just that, not failures. Coming back after a break is just coming back.

Inside Tendi

Built for the weeks you have capacity and the weeks you don't.

Check-in

Start with one mood.

A mood alone is enough, and Save is always explicit. Add activities, a note, a recording, or a photo only when that context feels useful.

Journal

Keep the details you care about.

Search and filter Journal for a specific moment, or revisit entries as pressed-flower specimens in the Herbarium.

Insights

See what a pattern is based on.

Tendi shows patterns across the entries you saved and explains what each one is based on: the counts behind it and the exact dates it covers. When a pattern includes a comparison, that comparison is not a cause-and-effect claim, and Tendi does not diagnose you or tell you what to do next.

Visual memory

A record that stays legible as it grows.

Month Map gives entries calendar context. Journal keeps them easy to find. Herbarium collects them as pressed-specimen memories.

Month Map
View your entries across the month, with each day reflecting the moods you recorded. It makes the shape of your recent days easier to scan.
Journal
Search and filter your entries by date, mood, activities, and notes. Your history is easy to find when you want to revisit a specific moment.
Herbarium
Browse your entries as pressed-specimen memories, gathered into a visual archive. A way to revisit what you’ve recorded.
Account No Tendi account required
Journal Journal content stays off Tendi servers
Analytics Optional analytics are off by default and never include journal content

Privacy

Your journal stays off our servers.

Tendi stores your mood entries, notes, photos, voice notes, and insights on your device by default. If you enable iCloud sync, your data syncs through your personal Apple iCloud account, not a Tendi journal server.

From Two Desks

A place to come back to yourself.

We started Tendi after getting tired of apps that made absences feel like failures. We wanted a private place to note what changed, see the context that mattered, and come back without being scolded.

Use Tendi when it helps. Leave it alone when it doesn't. Coming back after a break is just coming back.

— Harry & Vasso, Two Desks

FAQ

A few practical answers.

Is my data private?

Yes. Journal content is stored on your device by default. If you enable iCloud sync, it syncs through your personal Apple iCloud account, not a Tendi journal server.

How much does Tendi cost?

Tendi 1.0 launches free, with no ads, no subscriptions, and no in-app purchases. If you’d like to support the work, you can buy us a coffee.

When does it launch?

Tendi is planned for autumn 2026. Join the list and we will email when it is ready.

Do I have to check in every day?

No. There are no streaks, no catching up, and no deficit counters. Days without entries stay just that, not failures.

Can I get my journal out?

Yes. A full Tendi backup is designed for restoring your journal into Tendi. JSON and CSV carry entries for use elsewhere, and PDF is a readable report rather than a backup. Export and restore need no payment and no account.

Which devices are supported?

Tendi supports iPhone on iOS 17.2 or later, with an Apple Watch companion app for watchOS 10 or later so you can make quick check-ins from your wrist.

Do I need an account?

No. Tendi is built to work without an account.
