A no-nonsense workout tracker for people who actually lift. No accounts. No cloud. No subscriptions. Just the bar.
Long press any weight field to open the gearbox. Swipe up or down to increment in 1, 2.5, or 5kg steps. Haptic feedback on every click. No keyboard, no fat-fingering.
Volume splits across primary and secondary muscles. Compound-median strength/bodyweight ratio. 7-day trends with confidence indicators so you know how much to trust the numbers.
Your last session pre-fills as ghost sets — dimmed, ready to confirm or beat. Progressive overload built into the logging flow, not bolted on after.
Export your full training history as a structured prompt. Paste it into any LLM and get real coaching feedback. Your data, your AI, no middleman.
Strength and volume PRs flash live the moment you confirm a set. A snapshot of your best lifts is taken at session start so checks are instant — no lag, no delay.
Kill the app mid-set. The session comes back exactly where you left it — every set locked in, timers restored, draft saved every 5 seconds automatically.
Filter PR progression by bodypart or individual exercise. Track cardio over time. See exactly which days you trained with a calendar view. Export everything at any time — no paywall, no subscription needed to access your own data.
You already know what you lifted last week. You want the app to know too — and tell you whether it was better or worse, without making you pay for the privilege.
Strong, Hevy, Fitbod — they all want $10–15/month for features that should be free. Iron Log has no subscription tier, no free limit, no upsell. Everything works, always.
Your training history is yours. No login, no cloud, no company that can sunset the app and take your data with it. Backup to a file. Restore anywhere. No permission needed.
Every session is exportable as a structured AI prompt. Paste your history into ChatGPT and ask it anything — volume analysis, programming critique, deload timing.
Tonnage per bodypart. Compound-median strength ratio. Week-over-week deltas with confidence scores. If the number looks wrong, the app tells you why.
Long press to adjust weight in 2.5kg steps. Ghost sets pre-fill from last session. Confirm, move on. No keyboard, no tapping, no slowing down mid-lift.
Most fitness apps are built around retention metrics, subscription tiers, and cloud lock-in. Iron Log was built for a different reason — to actually be useful in the gym.
Everything lives on your phone. No server ever sees your data. If the app disappears tomorrow, you still have everything. Export to JSON anytime, restore anywhere.
Free. No ads. No upsell. Built by a lifter, for lifters.
