How far and how fast you moved, how much of the match you spent at the net, how many shots you hit, your best moments as clips, and the one thing to work on next.

No. Rally follows the players, not the ball, so it cannot tell who won a point. Everything it shows is about how you moved and hit.

Yours: the side you said you played on, and the player you tapped on the first frame if you did. It can only follow the two players nearest the phone. Filming.

Your first match is free and complete. After it, one match a month is free, and Rally Pro analyses every match, starting with a free trial. A match Rally could not follow you in does not count.

About a minute after the upload you see how much play Rally found. The fix and the full result follow a few minutes later for most matches. Rally tells you when it is ready, so you can close the app.

Usually the phone was on the far side, part of the court was out of the picture, the phone moved, or there was too little play. Rally says so rather than show numbers it does not trust. The guide shows what works. Filming.

Up to 15 minutes. Film a few games or a set; a longer match can go up in parts.

It is an estimate from one phone. Small differences in the video move distance and the other numbers by a few percent, so look at the trend over several matches, not one number.

Only this phone. The upload is deleted once it is analysed; your clips stay 30 days and the numbers until you delete them. Read the full privacy policy.

Choose Coach in Settings and Rally adds the telemetry, the full list of faults behind each fix, and Progress across matches.

Settings → Delete my data. It removes every match, clip and number, on the server and on this phone.
