One Line: Tasks & Notes

One Line: Tasks & Notes is an iPhone app that files each line you write as a note, a task, or an event. You never have to create a folder or memorise a tag syntax. The same writing carries on at oneline.date.

Frequently asked questions

The app filed something in the wrong place. How do I fix it?

Tap the item once and switch it to a note, a task, or an event. There is no setting to change and no rule to register.

If the date or time was picked up incorrectly, you can edit it on the item itself.

Do I need an account?

Not for the app. Install it and start writing; it works without an internet connection.

Signing in is needed to carry on across devices. You sign in with your Apple account, and on the web with a Google account as well. There is no separate password to create.

How does sync between devices work?

Once you sign in, your writing is stored on our servers and appears on every device and browser signed in to the same account. Syncing your writing is free.

If the same item is edited on two devices, the one saved later wins. An item you delete does not come back on another device.

If you would rather not sync, leave the storage location set to This device only and nothing is uploaded.

How do I use it on the web?

Open oneline.date in a browser and sign in with the same account as the app. Today, Notes, Calendar and the one-line input are in the same places as in the app.

Reading, writing and editing are free. Signing in is all it takes, and you do not need the app to start.

The only thing Pro adds is keeping attachments in the cloud.

Purchases happen only in the app. Nothing is sold on this website and there is no checkout here.

What about attachments such as photos and recordings?

Attaching files on your device is free. Keeping attachments in the cloud so that other devices and the web can open them is the Pro feature.

A free user's writing still syncs; only the attached files stay on the device that holds them, and other devices show a placeholder.

How do I back up and restore?

Use the backup export feature to save all of your data as a single file. Keep the file wherever you like — the Files app, iCloud Drive, and so on.

To restore, choose that file in the app's restore feature. Use the same steps when you move to a new device.

Backup export and restore are free and do not require a subscription.

How do I cancel my subscription?

Cancellation happens in Apple's settings, not in the app. On your iPhone go to Settings → [your name] → Subscriptions, select One Line, and tap Cancel Subscription.

After cancelling you keep Pro features until the end of the period you already paid for.

Cancelling does not remove your notes, tasks, or events. They stay on your device and keep syncing between devices, and you can still carry on in the browser. Only cloud storage of attachments stops.

Refunds are handled by Apple. Please use Apple's Report a Problem page.

What do I get for free?

Unlimited notes, tasks, and events; one-line sorting; calendar; reminders; widgets; backup export and restore; syncing your writing between devices; and reading and writing on the web — all free, with no item caps and no ads.

Pro adds one thing: cloud storage for attachments.

Pricing and purchase are shown on the purchase screen inside the app.

Is what I write sent to a server?

Not for sorting. Reading your text and filing it as a note, task, or event happens entirely on your device. There is no analytics SDK and there are no ads.

If you sign in and turn on sync, the writing itself is uploaded so that it can be stored. See the privacy policy for details.

I want to delete my account and everything on the server.

Tap Settings → Account → Delete account in the app. Your account and everything stored on the server, attachments included, are deleted immediately and irreversibly. There is no request procedure and no waiting period.

Data on the device is deleted along with the app. Export a backup first if you want to keep it.

I found a bug, or I have a feature idea.

Write to manager@x-ti.org. Telling us what you were doing when the problem appeared, and attaching a screenshot if you have one, helps a lot.
