Your toss drifts behind your head. ServeFix sees it — you can't. Record a serve, get your #1 fix and a drill in seconds. No cloud. Video never leaves your phone.\n\nServeFix analyzes your serve technique in seconds — toss, trophy pose, hip rotation, contact height, knee bend, and stance. Your first analysis is free: see your serve with the skeleton overlay, your #1 mistake to fix, and the one thing you're already doing well. No sensors. Built for players who practice alone and want real feedback without a $30/month subscription or a court-mounted camera.\n\nWHY SERVEFIX\n\nMost tennis apps either measure serve speed or record full matches. ServeFix does something different: it breaks down your serve technique and tells you what to fix. It's a serve coach in your pocket — not a radar gun, not a match tracker.\n\nHOW IT WORKS\n\n1. Record a serve or upload from your library (3-15 seconds)\n2. Stand side-on so your full body is visible\n3. Free: your serve video with skeleton overlay, your #1 mistake and its fix, and your #1 strength\n4. Pro: the full ranked fix list, a drill for every issue, unlimited re-tests, and your analysis history\n\nWHAT WE CHECK\n\n- Toss placement at trophy\n- Elbow height in the trophy pose\n- Hip rotation through contact\n- Contact height and extension\n- Knee bend in the loading phase\n- Stance angle\n\nBUILT FOR PRIVACY\n\n- Video stays on your device — never uploaded\n- No account or sign-in\n- Anonymous usage stats only — your video never leaves your phone\n- Optional: save your clip to Photos\n\nSERVEFIX PRO (OPTIONAL)\n\n- Unlimited serve analyses\n- Every ranked fix, not just the first\n- Personalized drill guidance for each issue\n- Full analysis history and side-by-side comparisons\n- Same on-device privacy\n\nPerfect for beginner and intermediate tennis players who want to improve their serve technique without expensive coaching or equipment.\n\nQuestions? support@servefix.vlastis.org\nTerms of Use (EULA): https://servefix.vlastis.org/terms\nPrivacy Policy: https://servefix.vlastis.org/privacy","facts":{"developer_id":6773095018,"developer_url":"https://servefix.vlastis.org","first_released":"2026-06-04T07:00:00Z","support_url":"https://servefix.vlastis.org/support","privacy_url":"https://servefix.vlastis.org/privacy","website_url":"https://servefix.vlastis.org/","app_version":"2.3.","release_notes":"This update makes your results easier to read.\n\n• Larger serve replay, so the skeleton and green target are easier to see\n• Green target wedges merged into one clearer shape\n• Try again, Share, and Help moved from the bottom bar to the top\n• The drill sits with the replay\n• A shorter progress card on Home","rating_current_version":null,"rating_count_current_version":0,"star_counts":[0,0,0,0,0],"genres":["Sports"],"languages":["EN"],"content_advisories":null,"device_families":["iphone"],"made_for_iphone_duo":false,"chart":null},"freshness":{"apple_read_at":"2026-11-12T20:16:12.875Z","catalog_read_at":"2026-11-13T21:39:13.298Z","reviews_checked_at":null,"summary_written_at":"2026-11-12T21:30:13.015Z","placed_at":"2026-11-12T20:40:13.233Z","scored_at":"2026-11-13T21:46:12.829Z"},"editorial":{"one_liner":"Analyzes a recorded tennis serve on-device and flags the technique fix to work on first.","what_is":"ServeFix is a tennis serve analysis app that checks toss, trophy pose, hip rotation, contact height, knee bend, and stance from a recorded or uploaded serve clip.
