Timers Built for Mid-Set, Not Mid-Scroll
A workout timer gets used with shaking hands, sweat on the screen, and thirty seconds of rest to set up the next round. So the tabata timer here leads with what matters at that moment: digits you can read from across the room, color-coded work and rest phases, distinct audio cues for every transition (double-beep into work, a low tone into rest, 3-2-1 ticks), and a fullscreen mode with no ads in it. The schedule is computed drift-free from timestamps, so round 8 ends exactly when it should — including the original 1996 Izumi Tabata 20/10 protocol as a preset.
Calculators That Respect Real Equipment
The warmup sets calculator does the math the plate rack imposes: tell it your working weight, bar, and which plates your gym actually has (tap away the missing ones), and every warmup set comes back rounded down to a weight you can physically load, with the per-side plate breakdown drawn for you. The equal playing time calculator does the same for coaches: it only offers substitution schemes where mathematically equal minutes are possible for your roster size, then rotates the bench round-robin so no kid sits twice before everyone sat once.
No Accounts, Ever
Generated plans from the bodyweight workout generator, your equipment choices, timer presets, and team rosters are saved in your own browser only. Nothing to sign up for, nothing synced to a server, nothing to delete later — which also means the tools load fast and keep working if the gym Wi-Fi drops mid-session.
