For iPhone
You locked it. Here’s the proof.
Confirm the door, the stove or your meds once with a tap, your voice or a photo. Later, when the doubt creeps in, check the record instead of driving back.
Sound familiar?
You did it on autopilot, so the memory never stuck. Each of these explains why, and what to do about it.
How it works
Make a Loop
One for each thing you tend to doubt: the door, the stove, your pills. Presets get you started in seconds.
Close it your way
A single tap when you’re rushed. Say it out loud for a voice note. Or snap a photo of the locked door, stamped with the time.

When the doubt hits on the bus, open the app. You’ll see exactly when you did it, with the proof.
A look inside
Built to be calm
Most apps want you to come back. This one wants you to stop thinking about the stove.
- No streaks, scores or red badges. Nothing to keep up with.
- One nudge, never a stream. A daily reminder or a countdown like “check the stove in 20 minutes”.
- One-time Loops for trips and one-offs. They tidy themselves away after 24 hours.
- Private by design. No account, no sign-in, no cloud. Your loops, photos and recordings never leave your phone, and it all works offline.

Questions people ask
What does One Loop do?
It keeps a timestamped record that you did something routine, like locking the door or taking a pill. You confirm it once with a tap, a voice note or a photo, and check the record later instead of going back.
Is it a to-do list?
No. A to-do list tracks what you still have to do. One Loop records what you already did, so you can stop wondering whether you did it.
Where are my photos and recordings stored?
On your iPhone, inside the app. They are not added to your camera roll and never uploaded. There is no account and no cloud sync.
Does it work offline?
Yes. Everything works in airplane mode, because nothing needs a server.
How much does it cost?
One Loop is free to download with a 7-day free trial. After that, One Loop Pro is $2.99 a week, $24.99 a year or $59.99 once (US prices).
Will it keep sending me notifications?
No. You can set one daily reminder or a one-off countdown, like “check the stove in 20 minutes”. It sends one nudge and that’s it. No streaks, no badges.
Confirm it once. Stop wondering.
