About this app

Repply is a straightforward interval timer for anyone who trains in rounds. Set a work period, a rest period, and the number of rounds, then start — Repply counts down each phase with a big, clear display and audible cues so you always know whether to push or recover without looking at the screen. It is built for circuit training, HIIT, stretching, boxing rounds, or any routine that alternates effort and rest.

The main timer screen keeps everything you need in view: the current phase, the time remaining, and how many rounds are left. Colour and sound change between work and rest so you can keep your eyes on your training and your hands free. Presets let you save the interval structures you use most, so your favourite routines are one tap away instead of being rebuilt every session. Whether you do 30 seconds on and 15 off or long work blocks with short breaks, the setup is quick and the timer handles the rest.

The Guide screen explains how to configure intervals and offers simple tips for getting the most out of interval-style training, with a plain reminder that the app is a timer and not medical or fitness advice. Settings let you adjust sound, vibration, and whether the screen stays awake during a session. There is no account to create and no personal data required — open Repply and start your first interval in seconds.

Repply works fully offline and shows no advertising. There is no advertising identifier in the build, and nothing you enter is sold or shared. It is designed to be light, reliable, and distraction-free — a dependable interval timer that stays out of the way so you can focus on the work.
