GridsDrum is a practice tool for drummers who want to build stronger time, reading, coordination and vocabulary. Create short sticking ideas, place them on a rhythmic grid, and practise how they move through different rates, bars and placements. Use the main grid for focused repetition, then explore tools such as guided practice rooms, speed training, ghost reading, scatter placement, custom grids, combo building and presets. The app is designed for real practice sessions: fast to open, easy to repeat, and deep enough for advanced coordination work. Key features: - Grid-based drum practice - Sticking and vocabulary input - Practice rooms for speed, reading, coordination and linear drills - Combo tools for layered and sequenced ideas - Presets for saving routines and setups - Optional Pro subscription for deeper practice tools GridsDrum works on iPhone and iPad. No account is required to start practising.
