Why it exists
The problem
The best interval timers are paid ($7.99 Seconds Pro) or free-with-ads that upsell a subscription; most free ones are unreliable in the background or nag between rounds.
What's different
How Roundbell stands out
Roundbell is a completely free, full-screen interval timer: colour-per-interval screens legible from across the gym, bell + 3-2-1 beeps + voice + haptics, 8 presets and unlimited custom circuits, background-safe timing, history and streaks, and an opt-in daily motivation. No ads, no account, no subscription.
