A workout heatmap for every exercise, daily, weekly, and monthly volume with pace in reps per minute, averages, trend lines, and the exact rep count standing between you and the next rank.
TAILORED TO YOUR RESULTS
Performance tiles compare this week against your averages, and the recommendations read like marching orders: what is on track, what slipped, and exactly how many reps recover the ground.

BRIEFING
QUESTIONS
What is a HIIT timer?
A HIIT timer is an interval timer built for high intensity interval training: short bursts of hard work separated by short rests. RankTime is a HIIT workout timer for iPhone that guides each interval with color, sound, and haptics, so you never have to look at the clock mid set.
What is a Tabata timer?
Tabata is the classic HIIT protocol: 20 seconds of all-out work, 10 seconds of rest, repeated for 8 rounds, 4 minutes total. RankTime ships with Tabata as a preset, and the ring on this page is exactly how the app draws it before you press play.
What does EMOM mean?
EMOM stands for every minute on the minute: you start a fixed set of work at the top of each minute and rest with whatever time is left. In RankTime you can run EMOM by time or give each exercise a rep target and let the app pace the session.
Can I build my own interval workout?
Yes. RankTime is a fully custom interval timer: any number of exercises and rounds, your own work and rest durations, time mode or reps mode, and mixed or continuous exercise order. Save it as a preset and it syncs across your devices through iCloud.
Does the workout timer track heart rate?
Yes. RankTime reads live heart rate from a Polar H10 chest strap, Apple Watch, or any Bluetooth heart rate sensor, shows five color zones during the workout, and saves the samples to Apple Health with your permission.
What makes RankTime different from other interval timers?
Rank. Every rep you complete counts toward a 21-tier military rank ladder per exercise, with medals for consistency and shareable achievement cards. The timer starts the workout; the service record keeps you coming back.
