## What is Pacelab Intervals?

Not another workout app. I know. But after 10 years of functional training, I couldn't find one that fit: flexible enough to mix block types, no hidden subscriptions, no paywalled pro features, no clunky old UI. So I built my own. From an athlete, for athletes.

Pacelab Intervals is the workout timer and builder for people who know how to train and don't want the rest. Build your workout. Run it. Share it.

WORKOUT BUILDER
Create custom workouts with 6 block types: Tabata, AMRAP, EMOM, Circuit, Rounds and Timed. Mix them in a single workout. Progressive reps and time: increase or decrease per round. Add exercises, set work and rest, configure rounds. Exactly how you program.

TIMER
Voice countdowns, auto-progression between blocks, back/skip navigation, pause and resume. See every block, round and exercise before you begin. No surprises during your workout. Just start and move.

SHARE YOUR WORKOUT
Share a link. Athletes, training partners, or friends import it directly into their app in one tap.

SCHEDULE & TRACK
Schedule workouts, get reminders, track history and personal records. Streaks, session stats, and health app sync.

BUILT FOR
CrossFitters. HIIT athletes. Personal trainers. Home athletes. Anyone who programs their own training and needs a reliable tool to build and run it.

Free. Minimal. No subscriptions.
No videos. Just your workout, running.
