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.
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.

Per exercise, the app tracks lifetime reps, your recent pace, and projects when the next rank lands: 1LT in about 70 days, BG in about 136. The bar keeps filling; the ladder keeps climbing.

Workout history, notes, and labels export whenever you want. Everything is stored on device and in your own iCloud, never on our servers.
Every week a completed tour. Carry on, soldier.
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.
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.
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.
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.
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.
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.
