C24 Cardio
A focused cardio interval timer designed around structured work and rest.
Overview
C24 Cardio is a focused cardio interval timer I built for structured work and rest. You set rounds, round duration, and rest, run the session, then keep training history and progress on the device. There is no account to create.
Role
Designed and developed as an independent mobile product.
How it works
01
Set the session
Choose rounds, round duration, and rest between rounds. Preset values are available, along with custom settings.
02
Start the workout
Start Workout begins the session from the setup screen.
03
Train the interval
The session opens on a GO cue, then a WORK timer with the current round count.
04
Control the session
Sound can be turned on. Pause and Stop Workout are available during the session. Ending a session early is confirmed, and that session is not saved.
05
Review progress
Progress shows sessions, rounds, and training time across today, this week, this month, and all time, plus weekly activity, current streak, and records: best session, longest session, and best day.
