# Thea vs Proll

The clearest difference is monetization model: Proll at free against Thea's free with in-app purchases. Thea's advantage is ratings volume (2K vs 8) and device support (4 vs 2). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Thea sells 2 in-app purchases, starting at $12.00 per month and Proll sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Thea against 4.9 for Proll. That said, the two scores are not equally well evidenced: Thea has 2K ratings behind it against 8, so its average is the more settled of the two. Written reviews are what separate them: 95% of Thea's written reviews are positive against 100% of Proll's.

Thea ships an update monthly, Proll every 2 months. The most recent releases landed on September 29, 2026 and July 23, 2026 respectively.
