The Gap app by CausalMe

Don't just know what. Know why.

Your watch shows what happened. The Gap helps you find what's behind it, using your own data, not averages from other people. It's an iPhone app that works out which of your habits seem to move your sleep, HRV and recovery.

Launching on the iPhone App Store soon

How it works

1. Connect

Link Apple Health (which brings in Apple Watch data), or Whoop, Oura, Strava, Withings or Polar. No wearable? Your iPhone still gives sleep and steps.

2. Check in

A quick daily check-in and easy logging of food, water and workouts, by tapping, typing or talking to Siri.

3. Discover

The Gap tests which habits seem to change your numbers, and shows you the ones that hold up in your own data.

What's inside

Your day at a glance

Sleep, recovery and HRV from the sources you connect, compared with your own normal for that day of the week, with a short plain-English note.

A 10-second daily check-in

Stress, alcohol, caffeine, screen time, a busy day, travel. Or say "Hey Siri, log to The Gap" for water, coffee, food or a note.

Discoveries from your own data

When a pattern in your own days holds up, it opens as a discovery. Findings are labelled early or confirmed, so you always know how sure it is.

Nutrition

Log food by search, barcode, or just describe the meal. See calories, protein, carbs, fat and sugar for the day, and set goals for protein, water and sugar.

Training

Ready-made workouts or your own, suggested weights each session based on your own lifts, a weekly workout ring, personal bests and multi-week programs.

Gappy, your assistant

Ask a question in plain words about your own sleep, recovery or habits and get an answer based on your data. AI features are optional and can be switched off.

Honest by design

Early or confirmed

A pattern is called early until it has held up for long enough, and confirmed only after it passes checks that adjust for other things going on and for the chance of finding patterns by luck.

It takes a few weeks

The first patterns usually need a few weeks of days with both the habit and the reading. The Gap tells you how far along each one is, instead of guessing.

Your data, your control

Your data isn't sold and there are no ads. You can export or delete everything from inside the app, and AI features can be switched off.

Not medical advice

The Gap shows patterns in your own data. It is general information, not medical advice, and not a substitute for a doctor or other health professional.

Works with

Apple Health, Apple Watch, Whoop, Oura, Strava, Withings, Polar.

Garmin data can come in through Apple Health today (some measures, such as HRV, may not). A direct Garmin connection is being built. Direct Whoop and Oura connections have limited places at launch; Apple Health always works.
