For Together detection to work, check that:
- You both have it switched on — You → Privacy → Together detection.
- bluumie is open on both phones. Detection doesn't run in the background.
- Location is allowed for bluumie on both phones (approximate location is enough).
- You're actually close together.
- Bluetooth detection is on, if you'd like better accuracy.
- bluumie is up to date — see How do I update bluumie?.
If it still doesn't pick you up, log the time yourself — it counts just the same once confirmed.
