Most workout trackers for Android want a subscription, an account, and permission to store your training history on their servers. Iron Log does the opposite — everything stays on your phone, works without internet, and costs nothing.
The Android fitness app market is flooded with apps that lock their best features behind paywalls or require cloud accounts just to get started. Iron Log was built differently — every feature is available from day one, no sign-up required.
Iron Log tracks volume per muscle group, compound strength relative to your bodyweight, week-over-week trends, and recent PRs — all calculated locally from your session history. No server needed.
The deep stats panel shows 7-day volume bars with confidence indicators so you know when a trend is statistically meaningful versus when it's just noise from two sessions.
Your full training history exports as TXT, CSV, or a structured JSON backup. There's also a built-in AI coaching prompt — paste your history into ChatGPT and get detailed feedback on your programming, volume balance, and recovery patterns.
If Iron Log ever disappears from the Play Store, your data survives. You're not renting access to your own training history.
Download Iron Log on Google Play — no sign-up required.
