Kiron: Gym & Cardio Tracker
Workout Journal, Log & Plans
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Paste any AI-generated workout plan — from ChatGPT, Claude, or Gemini — and Kiron turns it into a scheduled, trackable program. Strength, cardio, and recovery in one app.
Kiron turns any AI-generated workout plan into a program you can actually train.
Ask ChatGPT, Claude, or Gemini to write your plan, paste it into Kiron, and start training; no spreadsheets, no manual setup. Kiron reads real AI output and maps your exercises, sets, reps, and rest into a structured, scheduled program.
Your AI wrote the workout. Kiron runs it.
AI chatbots can write a workout plan or training program in seconds; but they can't track your training. Kiron is the workout tracker built for how people train today.
Paste your plan as plain text and Kiron instantly turns it into a structured, scheduled program; ready to follow and log set by set. No templates. No manual entry. No rebuilding your plan inside a fitness app. Just paste and start training.
Built for AI-generated workouts
Whether your plan came from ChatGPT, Claude, Gemini, a coach, or a spreadsheet, Kiron reads real-world formatting and maps your exercises, sets, reps, and rest automatically. Longer programs are even split into phases that run back to back; base, build, peak, and taper, scheduled for you.
Track every set
Log sets, reps, and weight with a fast, frictionless workout log. Follow your week day by day, track strength and cardio across multiple programs, and keep your full history at your fingertips. Watch your progress and hit new PRs.
Strength, cardio, and everything in between
Kiron isn't just a lifting log. Run, ride, row, swim, do intervals or conditioning; plus mobility and rehab work. A deep exercise library with muscle targeting covers strength, cardio, carries, timed holds, and bodyweight movements, so any program your AI writes is fully trackable.
Recovery built in
Kiron tracks muscle fatigue and recovery across your training, so you can see which muscles are fresh and train smarter, not just harder.
Apple Health sync
Completed workouts sync to Apple Health automatically, keeping your training connected with the rest of your health data.
