The TennisTrkr app saves your last three matches. From the main screen of the TennisTrkr app on your Fitbit, tap the bottom-left icon. Then tap a match listed to view previous match score and stats.

From the TennisTrkr, open the match settings by tapping the settings icons in the top-right. Change “Match Format” to “Best of 3 Sets”, and “Final set” to “10pt Tiebreak”. Then click “Save Settings”. From here, change the server if necessary, and press the play button in the bottom-right to start the match.

During a match, tap the arrow at the bottom to view current match stats.

TennisTrkr is compatible with the Fitbit Versa (1st generation), Fitbit Versa Lite, Fitbit Versa 2, Versa 3, Fitbit Ionic, and Fitbit Sense.
