Accurate swim time conversions

Swim Times Pro converts between long and short course (also known as LCM, SCM and SCY) swimming times for all major swimming events.

Swim Times Pro is the only iOS conversion app to use country specific conversions for the UK (ASA / Sport Systems), USA (NCAA, NFHS), Australia (Swimming Australia) and New Zealand (Swim NZ).

Just 69p on the App Store!


Swim Times Pro uses recognised conversions as documented by the relevant swimming authorities in each country

UK ASA / SportSystems

Swim Times Pro uses the same conversion method as the ASA and Sport Systems which means your conversions match the ones used by meet organisers.


Swim Times Pro uses the conversions from the NCAA 2013-2015 rulebook and from the 2013-2014 NFHS rules.

The app also converts from 25yd pools and allows for 500yd/400m and 1650yd/1500m conversions.

Swimming Australia

Swim Times Pro uses the Swimming Australia conversion constants. The app also converts according to age groups (14yrs & under; 15yrs & over)

Swim NZ

Uses Swim NZ conversion factors. This also allows for conversion from 3313 yard and 3623 yard pools

Works Anywhere

Unlike web sites, Swim Times Pro works anywhere, even when you don't have Internet access - a common problem in swimming pools!
