Set once, in the app
Settings screen: zł/h and zł/km thresholds, both conditions or one, separate Uber | Bolt tabs.
Acceptance under control.
Uber and Bolt each count your acceptance rate their own way, and you learn about it too late. The Kerzu bubble shows it live, on top of any app.

Uber and Bolt. One app.
The same numbers on the Bolt card, separate thresholds and one summary of your day. When you accept a ride in Uber, Kerzu reminds you to go offline in Bolt. Android lets no app tap for another, so you tap yourself.

Under the hood
- Your own colour thresholds zł/h and zł/km
- Uber | Bolt separate tabs
- Both conditions or one you choose
Bolt on par with Uber
- Bolt card and price We recognise the Bolt offer card and read the price; the overlay shows zł/h and zł/km as it does for Uber.
- Separate colour thresholds A separate set of thresholds and maximum pickup for Bolt (Uber | Bolt tabs), because its pickup times can differ.
- Auto-accept and trip end Offers that Bolt accepts automatically are recognised, and the end of a trip is spotted from the “Confirm price” screen.
- No-penalty rejections Bolt rejections that cost the driver no penalty do not spoil your acceptance rate.
- Bolt acceptance in the bubble A separate Bolt target and acceptance figure next to Uber's.
- One summary An Uber | Bolt split on the day and week pages, and an “Only Uber” / “Only Bolt” filter.
Uber and Bolt on one phone
- You accept a ride in Uber Kerzu sees it and immediately shows a reminder with a Bolt button.
- One tap: Bolt opens, you go offline You turn the reminder on with one switch in Settings, and Kerzu detects the installed app by itself.
- After the ride, a reminder: go back online When the ride ends, Kerzu reminds you to go back online in Bolt.
Android lets no app switch off another, so you tap yourself. Kerzu never taps for you.
Dashboard on your computer.

- Only the driver screenWhile recording, we read only the Uber Driver and Bolt Driver screen.

- Delete your account any timeIn one step, together with your data.
FAQ
Does Kerzu tap for me?
No. Kerzu only shows numbers. You accept and decline rides yourself.
Does it work with Bolt?
Yes, with Uber and Bolt, in one combined summary.
Do I need the accessibility service?
It is optional. By default Kerzu uses screen recording.
How much does it cost?
You can use it free for the first 7 days.
What about iPhone?
Planned.
How do I join the tests?
Open the Google Play open-testing page and join: Test on Google Play. You need an Android 10 or newer phone. The first 7 days are free.
Can Uber or Bolt penalise me for this?
Kerzu only reads the screen on your own phone. It never taps in their apps, never acts on your behalf and does not use their APIs. We cannot speak for Uber or Bolt or for their future policies, so the decision to use it is yours.
How much battery and data does it use?
Kerzu runs only while you record (from START to STOP). The data sent is mostly images of offer cards. We keep working to make it lighter.
