Titan sets itself up in a short run of onboarding screens. It connects to Apple Health, learns which device records your sleep, and asks about your training so it can put your scores in context.
01Device and data requirements
If you're new to Apple Health or want to check that your data is arriving, start with Set up Apple Health for Titan.
Titan runs on iPhone with iOS 26 or later. The Apple Watch app needs watchOS 26 or later. Titan reads everything from Apple Health, so any device that writes heart rate, heart rate variability, resting heart rate and sleep to Health can feed it. See wearables for other devices.
Wear your watch to bed. Recovery scores the overnight HRV and sleeping heart rate from your main sleep, so a night without the watch leaves Recovery to estimate.
02Set up Titan
Welcome
The first screen previews the Recovery, Sleep and Exertion scores you'll see each morning. Tap Get Started. If you left setup partway through, the button reads Resume setup and returns you to where you stopped.
Connect Apple Health
Tap Connect Apple Health and turn on every category in the iOS sheet. iOS never tells an app which read permissions you declined, so Titan cannot warn you about a category you left off. Not Now moves on without the sheet. You can review access later from the Health Permissions row at Settings > Health & Connected Apps. Settings is reached from the avatar on Today, then the gear on You. See Health permissions.
Choose your measurement system
Pick Metric or Imperial, and Calories or Kilojoules for energy. Titan starts with the usual units for your region. Change either one later at Settings > App Preferences > Units. See units and appearance.
Your details
Titan asks for your birthday, biological sex, height and weight. When Apple Health already has a value, Titan fills it in and marks it From Apple Health. Titan Age reads your date of birth from Apple Health, so keep it filled in there as well.
How do you track your sleep?
Titan lists the sources that have saved sleep to Apple Health, by name, and selects the one that recorded your most recent night. Pick the device you wear to bed. Titan uses it first and fills a night it missed from your other sources. Change it later at Settings > Recovery & Sleep > Sleep Tracker. See choosing your sleep source.
Your starting point
A series of questions covers your training. They include your main activity, what you're working toward, how often and how long you train, your training phase and plan, the days and equipment you have, and anything that limits your training. Some questions appear only when an earlier answer calls for them. Between questions, Titan shows your recorded workouts and training time from Apple Health for the last 28 days.
Your training, in context
This screen previews how Titan reads your training alongside today's Recovery and Exertion, your recent Recovery history and your training time.
Get a morning report?
Tap Turn On Notifications and allow the iOS prompt. Titan then turns on the Daily Report, which arrives at 7:00 each morning once your sleep is recorded. Not Now skips it. Stress Alert and the other notifications stay off until you turn them on with the bell on You. See notifications.
Upgrade to Pro
The last screen offers Titan Pro plans, such as Annual and a one-time Lifetime purchase. Continue Without Purchase finishes setup, and Restore Purchases brings back an earlier plan. See Titan Pro plans.
03When your scores become available
Titan reads the history already in Health, so a long history gives you full scores from the first day. On a new watch, each score waits for its own history.
| Score | History needed |
|---|---|
| Recovery | 15 measured nights, with overnight HRV and sleeping heart rate, in the last 60 |
| Stress | HRV and resting heart rate on 36 of the last 60 days |
| Battery | The same 36 of 60 days as Stress |
| Sleep | One recorded night |
| Exertion | None. It starts at 0 each day and rises as you move |
Until Recovery has its baseline, the Recovery card has no score and its screen reads "Not enough nights for a baseline". See personal baselines and how the Recovery score works.
04Your morning check-in
- Open Titan after you wake. Today refreshes on its own, and you can pull down to refresh again.
- Read your Recovery band. Low is 0 to 39, Moderate is 40 to 74, and High is 75 and above. Tap the card to see how your overnight HRV and sleeping heart rate compare with your baseline.
- Tap Sleep to see your score and which app and device recorded last night.
- Check your Exertion target and use the range to plan today's activity. It reflects your training goal and Recovery. See exertion target.
