Neaptide The Tideline
On the App Store

Get settled & surface

It opens to one thing.

A circle. Hold it for a few seconds and a session starts. That is the whole interface.

Most calming apps open with a menu, a questionnaire or a sign-up. That is a reasonable design right up until the moment you actually need one — because when you're overwhelmed, deciding is the first thing that stops working. Forty exercises in a list are useless exactly when it matters.

So Neaptide decides, and lets you overrule it in one tap.

This is the app's first screen. Press and hold it.

The name

The smallest tide of the month.

A neap tide is what happens when the sun and the moon pull at right angles to each other and the water barely moves — the quiet end of a range, not the absence of one. Twice a month, everything settles down.

The app is built on the same idea. It is not trying to make you feel nothing. It is trying to take the top and the bottom off the day.

The part nobody else builds

Two directions.

Not everyone who feels bad needs to slow down. Some people are running fast: racing thoughts, clenched jaw, can't sit still. Others are running slow: flat, foggy, numb, stuck. Telling someone who is already shut down to breathe more slowly points them further down.

Neaptide reads which way you're going, then picks accordingly. The screen changes colour with the direction, so within about three sessions the colour itself is the cue.

Low tide · Settle

Down when you're wired.

Long exhales, the physiological sigh, orienting, cold contact. The screen cools and darkens as the session runs, and the water line falls with it.

  • extended exhale
  • physiological sigh
  • orienting
  • cold contact
A Neaptide settle session: a dim blue screen reading “out — long”, with the words “nothing needs you right now” above the timer.

High tide · Surface

Up when you're numb.

A sharper rhythm, movement, bilateral tapping, sensory re-entry. The screen warms and lifts, and the water comes up to meet you.

  • sharp exhale
  • bilateral tapping
  • movement
  • sensory re-entry
A Neaptide surface session: a warm ochre screen reading “find something you can see”, with the words “keep coming up, a little at a time” above the timer.

Two words stay on screen the whole time. If the read is wrong, one tap fixes it mid-session without losing your place.

The read

It reads you from how you held the screen.

A handful of small things about the way your thumb behaved — how much it trembled, how far it drifted, how long it lay completely still, how your grip shifted, and how quickly you reached for the screen. Nothing but the touchscreen — no camera, no microphone, no motion sensors, no health data, nothing worn on your body.

It is a sensible default, not a measurement, and the app says so in plain words on the screen where it matters. You can overrule it at any point, including halfway through.

The Neaptide opening screen: a single dim circle with the word “hold” beneath it.The read screen: “You're running fast. Let's bring it down.” with a slow/fast toggle and a button reading “Settle me · 1:00”.
A session screen reading “hold something cold”, timer at 1:03.
Cold contact. No breathing involved.

What's in it

Thirteen resets. Not all of them are breathing.

  • Unlimited sessions, in both directions.
  • Haptic pacing you can follow with the screen face-down.
  • A screen-off mode that goes dark and keeps pacing you.
  • Your own session length — as written, one minute, or four.
  • A Lock Screen widget and an Apple Watch app.
  • Works in airplane mode, on the Underground, on a phone with no signal.

Why each one is here

Every reset tells you why it's there.

Each one carries a plain-language note about what the technique is generally used for, and where that understanding comes from. It's shown after the session rather than during it, because reading is not what you need mid-session.

Neaptide describes; it does not diagnose. It is not treatment, and not a substitute for care from a professional. If you are in crisis, contact your local emergency number.

The close screen with its source note open, explaining what sensory re-entry is generally used for, above a reminder that Neaptide is not treatment.
The closing screen: “That's enough. Nothing to log. Nothing to keep up with.” with Again and Done buttons.

After

Nothing to keep up with.

  • streaks
  • scores
  • day 4
  • a log
  • a history
  • a chart
  • notifications

Miss a month and nothing is waiting for you when you come back. The session ends with two words and a way out.

Privacy

Nothing leaves your phone.

No sign-up, no email address, no cloud. There is no server for anything to go to. No analytics, no crash reporter, no identifier, no advertising. The only thing Neaptide keeps is the session length you last chose, and it stays on the device.
