Radio Backtime for the Psion Family

Backtime was written in 1992 as a small utility for broadcasters. The program was designed to aid radio presenters and ‘tech-ops”, by making the business of backtiming music and commercials easier.

Backtime was originally written for the Psion Series 3a/3c, and was ported to the Series 5 by request for one user in mid-1999. It was subsequently ported to the Nokia 9210 in September 2002 at the request of a user.


The author, Pete Sipple, worked in UK commercial radio, and designed the application to assist with complex show timing calculations.


Backtime is freeware. No further releases of this product are planned due to commitment with other projects.
