IronLog
The progressive overload tracker that tells you what to lift next
Progressive overload — lifting slightly more over time — is the single driver of strength and muscle growth. IronLog turns it into a system: it remembers every session, computes your next target, and celebrates every PR.
How it works
Log today's sets
Enter weight and reps for each set. It takes one tap per set — designed for chalky hands between lifts.
Get tomorrow's target
IronLog compares against last session and applies double progression: more reps until you top the range, then more weight.
Beat the number
Next session, your target is on screen. Hit it, and the cycle repeats — that's progressive overload, automated.
Everything an overload tracker should do
Smart Targets every session
IronLog applies the double progression rule automatically: hit the top of your rep range on every set and your next target jumps up in weight; miss it and you chase reps first. No spreadsheets, no guessing — the number you should lift is waiting when you walk in.
Last session, always visible
Every exercise shows exactly what you lifted last time — weight and reps, set by set — right next to today's input. Progressive overload stops being a memory test and becomes a simple instruction: beat that number.
Automatic PR detection
Set a new personal record and IronLog flags it the moment you log the set. PRs are highlighted in your history so your best lifts are never buried in a notebook.
1RM and volume analytics
The Progress screen estimates your one-rep max with the Epley formula and charts your weekly training volume, so you can see overload working — or catch a stall before it costs you weeks.
Works offline, syncs later
Gyms have terrible signal. IronLog saves every set on your device the instant you log it and syncs when you're back online — your overload streak never depends on Wi-Fi.
Built around your split
Push, Pull, Legs, or your own custom days — IronLog tracks progression per exercise inside the routine you actually run, with rest timers and drag-and-drop ordering.
Stop guessing. Start progressing.
Create your first split in under a minute. Your last session's numbers — and your next smart target — will be waiting every time you train.
