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
