The SWIMTAG wristband uses a combination of sensors to record your arm movement and position in the pool, this data is processed by our software algorithms into the data you see on your profile.

The accuracy of your swimming data will vary depending on how you swim. Irregular and erratic behaviour can introduce errors (eg. if you stop short of the end it may cut your length time short) but if you are swimming regularly accuracy will be good, split times for single lengths can vary as it is difficult to determine when you touch the wall, however times over a number of lengths will generally be accurate to the nearest second.

Sometimes a swim may not get processed correctly which means we will manually check it and upload it to your profile, if your swim is still not visible after 2 days send us a message using the feedback button.

SWIMTAG is designed to recognise all types of swimmers, however sometimes it can be difficult to pick out lengths if for example you stop halfway between lengths or don't stop at all between lengths. If your data appears inaccurate we suggest you try bringing your wristband out of the water briefly at the end of each length.

SWIMTAG recognises the 4 main stroke types (Freestyle, Breaststroke, Backstroke and Butterfly), we are currently working on introducing further training types such as kick-lengths and sculling. If SWIMTAG does not recognise your stroke style it will be marked as 'unknown', you will then be asked to update the stroke type yourself using the Swim Editor.

Yes, using the Swim Editor you can modify your swimming data, open the Swim Editor by selecting a length on the graph (ensuring the 'Custom Sets' button is not selected), or select 'Edit Swim' from the menu. Once you have made your changes SWIMTAG will recalculate your stats for you.
