Incallert 2.0 - free software that makes in-call “minute beeps” for S60 2nd Ed phones.
Incallert periodically generates sound beeps (which are normally heard only on your side) during phone calls. Use Incallert to make you conscious of your phone calls’ minute mark - at and before the minute mark - without having to look at the phone.
