CoachOn Tennis

CoachOn Tennis is the complete tennis toolkit for coaches, parents and players — track players, plan sessions, chart matches, analyse technique and follow progress, all in one place. MATCH CHARTING Chart matches point by point in singles or doubles. Set custom formats (best of 1, 3 or 5, Fast4, tiebreak rules, no-ad scoring), track rally lengths, and use the built-in coin toss to decide who serves. As you chart, watch live statistics build in real time — first-serve percentage, winners, unforced errors, break points and more — broken down set by set. A momentum chart shows exactly where the match turned. Made a mistake? Undo the last point instantly, or edit the format of the set in progress if you realise partway through it should be a tiebreak-at-3 instead of a full set. DRILLS & PROGRESS Create drills scored by points or by time, and log scores from a player's profile or run a whole squad through a session at once. Track goals, see leaderboards, and follow progress over time with comparison charts across players or sessions. Plan your sessions with the Session Planner and view any saved drill diagram — and with Pro, use the Drill Creator to design your own drills on a full tennis court: add players, cones, balls, targets and movement paths, animate the action, rotate to landscape for wider screens and tablets, and export. TECHNICAL ANALYSIS Annotate technique frame by frame over photos and video. Draw over serve technique with lines, angles and shapes, and step through footage one frame at a time to spot exactly what needs work — all included free. Upgrade to Pro to compare two clips or photos side by side and break down technique then versus now. STOPWATCH Time a drill for a single player for free. Go Pro to run the multi-timer — several stopwatches at once for a whole squad, each running independently — and log times straight to a drill score. BUILT FOR COURTSIDE USE Everything works offline — chart a match, log a drill or review technique with no signal. Your data is stored privately on your device, not in the cloud, and you can export a full backup at any time. FREE VS PRO Start free — everything you need to get going: • Up to 3 players, drills and matches • Full match charting and every charted match's stats • Drills, scores, timers, leaderboards and progress charts • Technical Analysis — draw over photos and video frames • Session Planner, plus viewing any saved drill diagram Go Pro to unlock the full toolkit: • Unlimited players, drills and matches • Lifetime statistics and averages across every match • Side-by-side Compare (photos and video) • Multi-timer for squad sessions • Drill Creator — design, animate and export drill diagrams • Downloadable, customisable PDF reports — players, matches, statistics and leaderboards Whether you are a coach running squad sessions, a competitive player tracking your own matches, or a parent following your child's progress, CoachOn Tennis keeps everything in one place — on the court and off it.
