Ægir Iron vs Liftosaur
Both apps go far deeper than a basic logger, but they aim at different lifters. The question is whether you want a programming language you can bend into any scheme, or a guided system that builds and progresses a periodized plan for you and takes it to a meet.
What Liftosaur does well
Liftosaur is a power-user's programming tool. Its scripting language, Liftoscript, lets you encode almost any progression or autoregulation logic, so you can reproduce a complex spreadsheet program exactly and have the app run it, rep calculations and all. It works on the web, iOS, and Android, runs offline, includes a plate calculator and graphs, handles any set-and-rep scheme including Olympic lifts, and is free to use with an inexpensive paid tier. For the lifter who genuinely enjoys building and debugging their own programming, and who would otherwise live in a spreadsheet, it is a superb fit.
Where Ægir Iron differs
Liftosaur hands you a language; Ægir Iron (also written Aegir Iron) hands you a system. Rather than scripting your progression, you answer a guided Program Wizard and get a complete Cycle / Block / Week / Day plan for your discipline, with percentage loading priced live from your training maxes, weak-lift emphasis, competition lift variants, and a meet peak, all editable afterward. Auto-progression then advances your training maxes from logged AMRAP sets each cycle and reprices the plan in one tap, so you get spreadsheet-grade logic without writing any. On top of that it adds the parts a solo programming tool does not focus on: meet planning with warmup and attempt selection, competition scoring across Wilks, DOTS, IPF GL, and Sinclair, honest load analytics (uncoupled ACWR with an EWMA companion, relative intensity zones, make rate from logged misses), and a real coach-and-athlete platform where athletes join by link and train free. Individual lifters use all of it free.
| Feature | Ægir Iron | Liftosaur |
|---|---|---|
| Programming model | Guided wizard + templates + full manual editing, priced from your maxes | Scriptable via Liftoscript, fully custom |

| Percentage & auto-progression | Live from maxes; AMRAP-driven training-max bumps | Whatever you script |
| Meet planning & scoring | Attempts + Wilks, DOTS, IPF GL, Sinclair | Not a focus |
| Load & intensity analytics | ACWR with EWMA companion, % of 1RM zones, make rate | Progress graphs |
| Coach and athlete platform | Yes, athletes train free | Solo tool; share programs by link |
| Sports covered | Powerlifting, weightlifting, strongman, calisthenics | Any barbell scheme you build |
| Cost for individuals | Free, full platform | Free with a paid tier |

Who should pick which
If you love engineering your own programming and want total control over every progression rule, Liftosaur is one of the most flexible tools available and worth the learning curve. If you want that same spreadsheet-grade logic without scripting it, plus meet prep, competition scoring, multi-sport support, and a coach-and-athlete workflow where athletes are free, Ægir Iron gets you there with a guided setup instead of a language.
