Frequently asked questions
I didn't get a notification when the timer ended
- Make sure notifications for Kairo are allowed in your device settings (Settings → Notifications → Kairo on iPhone, Settings → Apps → Kairo → Notifications on Android).
- Do Not Disturb, Focus modes and silent mode can hide or silence alerts.
- On Android, battery optimization can delay alerts. Allowing Kairo to run without restrictions helps.
Does the timer keep running if I leave the app?
Yes. The timer is based on the clock, so it keeps counting while you use other apps, lock your phone or even close Kairo. When you come back, it shows the correct remaining time. If Auto-start next phase is on, breaks and focus blocks continue one after another, and every focus block that finished while you were away is added to your statistics with its real end time. A cycle always stops after the long break.
How does the Pomodoro cycle work? Can I skip a phase?
A cycle has 8 steps: 4 focus blocks with a short break after each of the first three, then a long break. You can change the lengths in Settings.
To skip to the next phase, tap the phase name (for example Short break) above the timer and confirm. A skipped focus block still moves you forward in the cycle, but it isn't counted in your statistics.
How are streaks and the daily goal counted?
Every completed Pomodoro focus block counts as one pomodoro. A day counts toward your streak if you complete at least one pomodoro or one Focus session that day. Set your daily pomodoro goal in Settings → Daily pomodoro goal. Your progress appears under the timer and in Statistics.
I can't hear the background sound
Turn the sound on from the sound control on the timer screen and pick a sound. The sound slider controls your device's media volume, so check it isn't at zero. A phone call or another app playing audio can pause Kairo's sound.
My screen turns off during a session
Turn on Settings → Keep screen awake. The screen then stays on while a timer is running.
How do I turn off vibration?
Open Settings and turn off Haptic feedback.
How do I change the language?
Go to Settings → Language. Kairo is available in 26 languages and follows your device language by default.
How do I delete my data? Can I move it to a new phone?
Kairo has no accounts or cloud sync. Everything is stored on your device. To delete your history, open Statistics → Clear statistics. Uninstalling the app removes all of its data. Because nothing is stored on our side, statistics aren't transferred to a new phone automatically. See our Privacy Policy for details.
Is Kairo free?
Yes. Kairo has no ads, no subscriptions and no in-app purchases.
