# TM+ Pro vs Purpl PRO 2

The clearest difference is rating: Purpl PRO 2 at 4.0 against TM+ Pro's 3.1. TM+ Pro's advantage is in-app purchases (none vs 4) and ratings volume (97 vs 2). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Purpl PRO 2 sells 4 in-app purchases, starting at $19.99 per month. TM+ Pro asks for nothing beyond the download.

Purpl PRO 2 holds the better App Store score, 4.0 against 3.1. That said, the two scores are not equally well evidenced: TM+ Pro has 97 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 32% of TM+ Pro's written reviews are positive against 25% of Purpl PRO 2's, so the app with the better star average is not the one people write more warmly about.

TM+ Pro ships an update every 2 months, Purpl PRO 2 every 5 months. The most recent releases landed on September 22, 2026 and September 7, 2026 respectively.
