Titan reads sleep from Apple Health, and several apps and devices can write sleep there at once. Two settings decide which of them Titan uses. Sleep Tracker sets the source Titan reads first. The Sleep sources setting under Health & Connected Apps limits Titan to the sources you allow.
To open Settings, tap your avatar on Today to open You, then tap the gear icon.
01Sleep Tracker
Open Settings > Recovery & Sleep and tap Sleep Tracker. The menu lists the apps and devices that have saved sleep to Apple Health, by name, such as your Apple Watch, the Oura app, WHOOP, or AutoSleep. Sources that share a name, such as two watches with the same name, appear once. Titan leaves itself out of the list.
The default is Apple Watch, which reads any source with "Watch" or "Apple" in its name. When you pick a source from the list, Titan reads sleep saved by that app or by any source with the same name, so a replacement watch with the old name still counts.
If Apple Health lists no sleep sources or cannot be read, the menu shows a fixed list of common trackers instead, and the note under it says so. If the source you picked no longer appears in Apple Health, Titan reads sleep from every source.
Missing nights fall back to other sources
Sleep Tracker sets a priority. The note under the menu reads "Used first. Nights it missed come from your other sources." For each day, Titan builds the night from your chosen tracker first. If that tracker has no session ending on that day, Titan builds the day from all your sleep sources instead. With the Oura app as your tracker, a night you left the ring on the charger uses your Apple Watch sleep.
02Sleep sources in Health & Connected Apps
Open Settings > Health & Connected Apps and tap Sleep in the Apple Health section. The screen lists the sources that have written sleep to Apple Health, plus Oura when the direct connection is active. It has four controls.
- Primary Source, set to Automatic by default.
- Allowed Sources, one toggle per source.
- Duplicate Handling, set to Prefer Primary by default.
- Reset to All Sources, which clears every choice for Sleep.
Picking a Primary Source also turns that source on under Allowed Sources. Once any source is allowed, Titan reads sleep only from the allowed sources. This setting has no fallback. If none of your allowed sources recorded a night, that day has no sleep in Titan.
03Which setting wins
The Sleep sources setting wins. Titan checks it first, and Sleep Tracker only applies while Sleep reads All Sources there.
- Sleep on All Sources, tracker found in Apple Health. Titan reads your tracker first and fills missing days from all sources.
- Sleep on All Sources, tracker not found. Titan reads all sources.
- Sleep has a primary or allowed source. Titan reads only those sources and ignores Sleep Tracker.
The Sleep row in Health & Connected Apps shows All Sources when nothing is set. Any other value there means Sleep Tracker is inactive. To hand control back to Sleep Tracker, open Sleep and tap Reset to All Sources.
04Oura and the direct connection
Oura sleep can reach Apple Health through the Oura app or through Titan's direct Oura connection. The Oura support article covers both routes.
The Sleep Tracker menu lists the Oura app when it has saved sleep to Apple Health. Sleep from the direct connection is saved by Titan itself, so it does not appear in that menu. To make direct-connection sleep the source Titan reads, open Health & Connected Apps > Sleep and set Primary Source to Oura. The direct connection appears in that list only while Oura is connected.
05Picking a setup
If you track sleep with one device, leave Sleep on All Sources and set Sleep Tracker to that device. If you wear two trackers and trust one more, pick it as Sleep Tracker so the other covers nights the first one misses. If you want Titan to ignore a source completely, use the Sleep sources setting and accept that nights your allowed sources miss will stay empty.
When two sources overlap on the same night, Titan merges their samples. The sleep detection article explains the merge rules. If a night is missing, the missing sleep article walks through the checks.
