## What is Kruhac | Circuit Timer?

Kruhač is the circuit-training timer built for gym trainers and group-fitness coaches who need a reliable, distraction-free tool on the gym floor.

Set up in seconds
Dial in your stations, rounds, workout duration, and rest time — then hit Start. Kruhač takes it from there, driving the full session loop from countdown to celebration.                                                                                           

Never miss a transition
Configurable audio warnings count down the final seconds of every phase. Choose from 5 beep styles and 5 go-signal sounds, set independently for workout and rest starts, so your athletes always know what's coming.                                               

Save your favourite workouts
Store up to 4 named presets — each with its own station/round config, audio settings, and optional Spotify playlist link. Start any preset in two taps.                                                                                                             

Track your sessions
Every completed workout is logged automatically. Review session history, track participant numbers, and analyse training intensity and duration trends over day, week, month, or year.                                                                              

Built for the gym environment                                                                                                                                                                                                                                       
Full-screen phase backgrounds switch colour for instant peripheral-vision feedback. Six colour themes, per-phase gradient styles, and adjustable font sizes keep the display readable across any lighting condition. Screen stays on throughout the entire session. 

Spotify integration                                     
Link a playlist to any preset. When the session starts, Spotify opens straight to your playlist.                                                                                                                                                                    

Clean and focused
