Kiron

Track every rep see every gain

Free · In-App Purchases

Kiron is a program-first workout tracker for athletes who plan training ahead, log strength and cardio on iPhone, use Apple Health workout sync, and review progress in one place. Plan workouts before you train. Build personal programs with strength sessions, cardio sessions, progression targets, saved sessions, and reusable structure that fits the way you actually train. Log strength sessions while you train with sets, reps, weight, RIR, notes, supersets, rest timers, and previous performance close at hand. Track cardio with distance targets, duration targets, pace work, repeats, and intervals. Complete runs, walks, rides, rows, elliptical sessions, and indoor work from your phone or Apple Watch, then review route data, heart rate, pace, splits, interval segments, duration, energy, and effort. Use Apple Health workout sync to bring supported cardio workouts from Apple Fitness, Apple Watch, Strava, and other apps that write to Apple Health into your Kiron training history. Use the calendar to see what is coming up, start or resume the right session, move training days, pause a plan, or reschedule when the week changes. Kiron keeps the structure flexible so your training can keep moving when real life changes the plan. Track progress across strength and cardio with workout history, exercise history, volume and intensity trends, cardio analytics, and personal bests. Keep logging when the gym connection is poor, and Kiron will save your work locally, then sync when you are back online.

  • This app hasn’t received enough ratings or reviews to display an overview.

This update makes program editing smoother, notifications clearer, and Apple Health syncing more dependable. Program building has been refreshed with better session, exercise, set, and cardio editing flows, more reliable row taps and reordering, and easier week duplication. Apple Health and Apple Watch cardio completions now sync more reliably in the background, with extra protection and cleanup for pending health sync data. We’ve also made smaller stability, privacy, and polish improvements across the app.
