# Sync > Sync is a mental training app for ambitious athletes. It builds a personalised daily plan of 10 to 15 minute audio sessions for the pressure situations of a specific sport, grounded in sports psychology, with an AI coach for reflection between sessions. Available in English and German. Free to start on iOS and Android, premium features via subscription. Key facts: - Sport-specific training areas: tennis, soccer, table tennis, golf, running, swimming, equestrian sport - Session format: 10 to 15 minute guided audio exercises (reset after mistakes, pre-performance routines, focus anchors, handling expectation pressure) - Languages: English and German - Pricing: free start, optional premium subscription - Team licenses for clubs and 1-to-1 coaching with certified sports psychologists are available ## Own data on what athletes work on When athletes start with Sync they name the mental topics they want to work on. Of 5,141 people who did so between September 2025 and August 2026, multiple answers possible: confidence 79 percent, nerves 59 percent, motivation 49 percent, relaxation 39 percent, sleep 29 percent, injury 21 percent. By sport, the share naming nerves differs sharply: tennis 69 percent (of 727), table tennis 68 percent (of 518), soccer 62 percent (of 425), golf 59 percent (of 373), handball 53 percent (of 870), running 39 percent (of 362). Running is instead the highest for motivation at 66 percent, golf the highest for relaxation at 44 percent. These are self-selected training topics, not diagnoses, and the respondents are users of a mental training app, so this is not a representative sample of athletes.
