# MacroFactor vs Aja

The clearest difference is review sentiment: Aja at 100% against MacroFactor's 71%. Aja also leads on rating (5.0 vs 4.8). MacroFactor's advantage is ratings volume (23K vs 26) and update cadence (every 8 days vs every 5 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. MacroFactor sells 11 in-app purchases, starting at $9.99 per month and Aja sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Aja holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: MacroFactor has 23K ratings behind it against 26, so its average is the more settled of the two. Written reviews point the same way: 71% of MacroFactor's written reviews are positive against 100% of Aja's.

MacroFactor ships an update every 8 days, Aja every 5 weeks. The most recent releases landed on October 17, 2026 and October 9, 2026 respectively.
