Roundly - Interval Timer

Roundly makes interval training simple. Build custom timers for any workout — HIIT, Tabata, boxing, yoga, running, or anything else you train. Build Your Perfect Timer Create timers with multiple block types: warmup, work, rest, and cooldown. Set rounds, durations, and add notes for each interval. Customize your timer covers with colors, icons, or your own photos Stay Focused While Training Once you start a timer, Roundly keeps you on track with visual countdowns, sound cues, haptic feedback, and voice countdowns.
