About

Rhythm Count

Features
Read full description

Rhythm Count is a simple voice-based counting app that speaks numbers at custom time intervals. With three different counting styles, it can be used in a wide variety of daily situations. ------ Three Counting Styles 1. Count by Seconds Count one step per custom interval (for example, one count every 5 seconds). Perfect when you want clear, steady timing. 2. Rhythm Count Speak every second within one count and repeat the rhythm (for example: “1, 2, 3, 4, 1, 2, 3, 4…”). Ideal for keeping tempo, like dance or music practice. 3. Speak at Interval The counter runs every second, but numbers are spoken only at specific intervals (for example: “5, 10, 15…” every 5 seconds). Great for time awareness without constant voice output. ------ Flexible Settings • Count Up / Count Down • Unlimited or fixed count • Custom seconds per count or speaking interval • Voice selection ------ Example Use Cases Count by Seconds • Workouts, stretching, yoga (hold poses) • Meditation and breathing exercises • Study sessions (for example, one question every 30 seconds) Rhythm Count • Brushing teeth (equal time for each area) • Dance or music practice • Rhythm training and tempo keeping Speak at Interval • Turn-based games (announce every 10 seconds) • Quiz time limits • Group activities and exercises • Coordinating movement timing with others ------ Use it your way — Rhythm Count adapts to your rhythm, your timing, and your daily life.
