## Description

Call Timer is a handy Chrome extension designed to help users manage their phone call durations effectively. With this tool, you can set specific time limits for both outgoing and incoming calls, ensuring you stay within your network plan's calling packages like 10p or 15p per minute.

Features include turning call time limits on or off, customizable alert times with vibrations and warning sounds before your call time ends, and the ability to display a customizable clock during calls. Additionally, Call Timer supports an automatic callback function after the allotted time expires, making your call management seamless and efficient. For dual SIM users, it requires setting a default SIM for the extension to work smoothly.

## Review summary

Users find the Call Timer app useful for managing call durations and appreciate its simplicity. However, multiple users report issues with its functionality, especially for outgoing calls, lack of timely alerts, and auto-disconnect features not working on Android 9 and 10. Users also complain about long, unskippable ads post-call disrupting usage. The app works better on some devices and Android versions, mainly for incoming calls.

### Cons

- Auto disconnect feature does not work on newer Android versions (Android 9 and 10).
- App forces long, unskippable ads after calls which annoy users.
