You would have to keep a professional ringtone in your office at least to keep the office environment not disturbed by your ringtone.
But you don't have to keep the same ringtone at your home or at your holidays.
With the use of the Ringtone Scheduler Pro app, you can schedule different ringtone for different period.
1. Multiple schedule with schedule specific ringtone settings.
2. Keeping the schedule on/off.
3. When a particular schedule is started, your new ringtone will be set. At the end of the schedule, the ringtone which was there before the start of the schedule, will be set as the ringtone.
