Ægir Iron vs StrengthLog
Both apps are made for people who actually lift, and both have generous free tiers. The difference is scope: StrengthLog is a polished general strength logger, while Ægir Iron is built specifically for strength-sport programming, meet prep, and coaching.
What StrengthLog does well
StrengthLog is a clean, science-minded workout tracker with an unusually generous free tier. It ships a large library of free programs (including 5/3/1 and 5x5 variants), a big exercise database with instructions, straightforward set-and-rep logging, bodyweight and strength-standard tracking, and clear progress charts, with a premium tier that unlocks more programs and features. For general strength and hypertrophy training, where you mainly want a trustworthy logger and some proven routines to follow, it is an excellent and well-regarded option on iOS and Android.
Where Ægir Iron differs
StrengthLog is a strong general logger; Ægir Iron (also written Aegir Iron) is a specialist for strength sport and coaching. The programming goes further than following a routine: a guided Program Wizard writes a full Cycle / Block / Week / Day plan for your discipline with percentage loading priced live from your training maxes, and auto-progression advances those maxes from logged AMRAP sets each cycle and reprices the plan in one tap. On top of that it carries the competition layer a general logger does not: meet planning with warmup and attempt selection, and scoring across Wilks, DOTS, IPF GL, and Sinclair. It covers Olympic weightlifting, strongman, and calisthenics as first-class disciplines, adds honest load analytics (uncoupled ACWR with an EWMA companion, relative intensity zones as a percentage of 1RM, make rate from logged misses, and a recovery Body Map), and connects real coaches and athletes on a shared roster where athletes train free. Individual lifters use the full platform free on every platform.

Who should pick which
If you want a clean, science-based logger with a solid library of free programs for general strength training, StrengthLog is a great choice.
