10IS is a sports technology platform built for tennis players of all levels — from beginners to touring professionals. Powered by artificial intelligence, 10IS analyzes a player's racket specifications, playing style, swing characteristics, and injury history to generate a personalized string recommendation in seconds. Traditional string
selection relies on trial and error, word of mouth, or guesswork. 10IS replaces that process with a data-driven recommendation engine built on GPT-4o, delivering specific string families, gauge recommendations, tension ranges, and hybrid setup options tailored to each individual player. The platform includes a racket database of 130+ professional and recreational frames, a stringer finder that connects players with local string technicians, a full account system with recommendation history and restring reminders, and an AI chat assistant for ongoing string advice. 10IS operates on a freemium model — one free recommendation for all users, with Pro ($4.99 one-time) and Club ($1.99/month) tiers unlocking unlimited recommendations, advanced features, and the AI chat advisor. 10IS is developed and owned by Hevini Sporting, a tennis-focused sporting goods and technology brand. The platform launched in May 2026 and is publicly available at 10is.app.
