Hello Billiard

Hello Billiard is a carom billiards coach. Take a photo of the table and it reads the ball layout, then uses a physics simulation to suggest scoring paths with their success rates. It also calculates the classic three-cushion diamond systems. ■ Three-cushion (carom) • Five-and-a-half, Plus and Ball system calculators, with the diamond numbers drawn on the table • Physics paths for standard patterns such as around-the-table and back-and-forth shots ■ Photo recognition • Detects ball positions from a single photo of the table • Photos are processed on your device only and are never uploaded ■ Four-ball (Korean yotgu) • Physics engine with cut angle, spin and cushion rebound • Suggested routes that differ in direction and technique, each with an expected success rate • Beginner / intermediate / advanced recommendations ■ Game • Difficulty ladder: each player gets a different layout of the same difficulty — whoever climbs higher wins • Handicap, score race, daily layout, weak-spot drills and match records ■ Pro (in-app purchase: lifetime or 1-day pass) • All suggested routes, unlimited photo recognition, no watermark on exported images No ads and no sign-up.
