Your Watch reads your heart rate
Set a wake time and a window before it. Through that window the Watch reads your heart rate and picks the moment to wake you. The alarm lives on the Watch, so it still goes off if your iPhone is in another room.
5am Club is an Apple Watch alarm. It reads your heart rate through your wake window and picks when to wake you. Then the iPhone coach helps you get up a little earlier, a few minutes at a time.

Setup starts with one copy and paste

Help me set up 5am Club by Mr. Asad on my iPhone and Apple Watch. It's an Apple Watch alarm that reads my heart rate during my wake window to pick the moment to wake me. Take me through these steps one at a time, and wait for me to say done before you give me the next one. 1. Check my iPhone is on iOS 18 or later and my Apple Watch is on watchOS 11 or later. 2. On my iPhone, open https://apps.apple.com/app/id6833051479 and tap Get. 3. Open 5am Club, follow the setup and allow Health access. 4. Start the membership. If a friend gave me a code, tap Redeem a code instead. 5. Open 5am Club on my Watch. If it isn't there, open the Watch app on my iPhone, find 5am Club and tap Install. 6. On the Watch, allow heart rate, set my wake time and arm the alarm. 7. Remind me to keep my normal alarm on for the first week.

Pick a goal, like 5am. The iPhone coach suggests moving your wake time earlier a few minutes at a time. Nothing changes until you say yes.
Sleep and heart data stay on your iPhone and Watch. There's no account to make and nothing gets sent to a server of ours. Apple handles the payments.
