Read full description

ITT Assist is a tennis match assistant by Hitup Tennis for team captains and players. It is not an official ITT or USTA app. Key features: 1. USTA Assistant: After linking your player profile, see schedules across multiple teams, your complete season results, official NTRP information and a dynamic-rating reference. A dated chart shows how that rating changes over time. 2. USTA teams and opponents: Review rosters, competition standings, full schedules and scores for your team and upcoming opponents. Open completed matches to see partners, opposing players and set-by-set results. 3. Official ITT schedules and playoffs: See match dates, venues, courts, opponents and past scores. Playoff rounds show advanced and eliminated teams, followed by champion, runner-up and third place. 4. Team and player rankings: Team standings include records, total games and game differential. Player rankings are grouped by level and gender with global player search. 5. Cross-team profiles: After registration, see current and past results plus current and former teams. Players on multiple rosters can securely switch team identities. 6. ITTR trial ratings: Estimate a non-official rating from synced ITT results, lineup segments, wins and game differential. 7. Match scorecard: Record all six lines, lineups, substitutions, Overtime, Super Tiebreak and final totals. User scorecards are private and do not replace official results. 8. Avatars and profiles: Take or choose a photo, zoom and crop it, then securely sync the public avatar shown on player profiles. Public schedules and rankings do not require registration. Choose Apple or Google to sign in when viewing protected personal details, linking a USTA player profile or switching team identities. Each player identity can be bound to only one sign-in account. Continue using your original sign-in method and account across devices. Dynamic ratings are provided as a reference and are not official USTA ratings. If an identity appears to be claimed by someone else, users can contact hituptennis@gmail.com from the app.
