# Macroai.ai vs Lean

The clearest difference is ratings volume: Macroai.ai at 9 against Lean's 1. On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Macroai.ai sells 14 in-app purchases, starting at $4.19 per month and Lean sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Macroai.ai against 5.0 for Lean. That said, the two scores are not equally well evidenced: Macroai.ai has 9 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 6 days. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
