Honest, side-by-side comparison of Ignia and MacroFactor. Where each one wins, where it loses, and which to pick for which job.
The most accurate adaptive TDEE on the market — and they charge for it.
When the other tool is the right pick
MacroFactor is the closest thing to a direct competitor on adaptive TDEE. Built by the Stronger By Science team, its algorithm is the most rigorous in the category and it is widely considered the best paid coaching app for serious lifters. If you want the most sophisticated version of this one idea and are happy to pay for it, buy MacroFactor — it is genuinely excellent. The differences are price and breadth: it costs about $72 a year with no free tier beyond a 7-day trial, and it does not do photo logging, barcode-free offline use, or fasting.
