# Cogni vs StudioAI

The clearest difference is ratings volume: Cogni at 1.7K against StudioAI's 1. StudioAI's advantage is rating (5.0 vs 4.7) and update cadence (every 4 days vs every 9 days). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Cogni sells 9 in-app purchases, starting at $4.99 per month and StudioAI sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

StudioAI holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Cogni has 1.7K ratings behind it against 1, so its average is the more settled of the two.

Cogni ships an update every 9 days, StudioAI every 4 days. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
