Workout timer for iPhone

Push further
without thinking
about it.

SneakyTimer quietly stretches your countdown a few percent, so you train past the moment you'd normally quit. When you're done, it tells you the truth.

How it works

Three steps. One small lie.

The order matters — the stretch only works because the reveal always follows.

1

Set your goal

Pick 30 seconds, 5 minutes, or build an interval workout with rounds, rests, and sets.

2

We stretch it quietly

The countdown runs a few percent slower than real time. It stays perfectly smooth — no freezes, no jumps, nothing to notice.

3

We tell you the truth

"You thought you trained 10:00. You actually trained 11:07." Every session ends with the real numbers.

The app

Built for mid-workout hands.

Big numbers, one-handed controls, and a dark interface that stays out of the way.

Sneaky Mode

Choose how sneaky.

Every mode stretches the work only. Rest periods always stay exactly as long as they say.

Fixed Free

The same hidden stretch every round. +5% and +10% free; any percentage with Pro.

Random Pro

A surprise stretch drawn from your range each session — you'll never know exactly how long you went.

Progressive Pro

The stretch grows a little every round, so the late rounds are the ones that push hardest.

Pro adds Random and Progressive modes, any custom stretch percentage, unlimited saved workouts, and your full training history.

Fair play, upfront. Sneaky Mode intentionally makes the displayed time differ from real time. You turn it on yourself, the app reveals the truth after every session, and rest periods are never stretched. Don't use SneakyTimer for medical, competitive, safety-critical, or official timing.
