Temper

Temper

Intermittent fasting with clarity.

A fasting timer that's the hero, not a dashboard. No calorie logs, no data flood. Just ritual and the one question that matters: how long have I been fasting, and what's happening in my body right now?

What it is

The timer is the hero

One tap, always the first thing you see. Calm typography, generous space, a single accent. Quiet over dense.

Phases as a heat ramp

The longer you fast, the hotter it glows, from cool slate through teal and gold to ember as autophagy kicks in.

No ads. No traps.

The core timer is free forever. Pro is a one-time purchase, never a subscription. Anti-predatory by design.

Availability

Temper is in closed testing and arriving on Android.

Coming soon to Google Play
