Set up

The setup card in the app links straight to the matching step.

The names in the settings can differ depending on the manufacturer, system version and language.

Your numberSo other Tembu users can recognise youPerson
  1. 1Open Tembu → Settings → Phone Number.
  2. 2Enter the number your contacts have saved for you.
  3. 3Save.
Your number stays on your device. Only a code derived from it is sent via Bluetooth.
  1. 1Settings → Notifications → Tembu.
  2. 2Turn on "Allow Notifications".
  3. 3Check Focus modes: add Tembu as an allowed app.
  1. 1Settings → Apps → Tembu → Notifications.
  2. 2Turn on "Allow notifications".
  3. 3Check "Do not disturb": add Tembu as an exception.
Once you decline the prompt, the system won't ask again. Then only via Settings.
  1. 1Open Control Centre and turn on Bluetooth.
  2. 2Settings → Privacy & Security → Bluetooth → allow Tembu.
  1. 1Open Quick Settings and turn on Bluetooth.
  2. 2Settings → Apps → Tembu → Permissions → allow "Nearby devices".
Bluetooth must be on for both phones – yours and that of the person you meet.
  1. 1Open Tembu → Settings → Proximity Detection.
  2. 2Turn it on and confirm the prompts.
Without Proximity Detection, Tembu cannot recognise people – even with Bluetooth on.
  1. 1Settings → Tembu → Location.
  2. 2Choose "Always".
  3. 3Turn on "Precise Location".
  1. 1Settings → Apps → Tembu → Permissions → Location.
  2. 2Choose "Allow all the time".
  3. 3Turn on "Use precise location".
Your device location is only processed on your device. Reminders trigger within about 200 m of the place.
  1. 1Settings → General → Background App Refresh.
  2. 2Turn it on for Tembu.
  3. 3Don't swipe Tembu away in the app switcher.
If you swipe Tembu away, iOS may pause proximity detection until you open Tembu again.
  1. 1Settings → Apps → Tembu → Battery.
  2. 2Choose "Unrestricted" or "Don't optimise".
  3. 3Samsung: Battery → Background usage limits → remove Tembu from "Sleeping apps".
Some manufacturers (Samsung, Xiaomi, Huawei) stop background apps particularly quickly. This step matters most there.

Frequently asked questions

Does the other person need Tembu?For reminders about people: yes. Tembu only recognises another phone if Tembu runs on it. Invite them via Invite in the app – you send the link yourself; Tembu never sends anything automatically.
Does the other person learn about my Rumbles?No. Your Rumbles stay on your device. Your phones only exchange a code derived from the number.
Does "nearby" mean we actually talked?No. Tembu detects proximity, not conversations. You decide whether a topic is done – with "Done" and a note on what you discussed.
How close do I need to be to a place?About 200 m. Save places by address or as a point on the map – under Places in the app.
Which data leaves my phone?Rumbles, recordings, photos and contacts stay on your device. The app sends usage statistics under a random installation identifier to Firebase Analytics, without names, e-mail addresses and Rumble content. When you use the map search, the search text or map coordinates go to OpenStreetMap; when you dictate, depending on the device, audio goes to your operating system's speech recognition. Details are on the privacy page. From Android 1.6.2, usage analytics requires optional consent. Decline or withdraw in Settings → Usage analytics. Earlier app versions do not contain these controls.
Do reminders appear on Apple Watch?Yes, if notifications from Tembu are allowed on your iPhone and mirrored in the Watch app under Notifications.
Is there a widget?Yes. Long-press the home screen → Widgets → Tembu. It lets you create Rumbles even faster. For incoming calls, Tembu shows the matching Rumble if you allow Phone & Call log.
