Verdict
The clearest difference is rating: Adept Roll at 4.8 against STL Master's 4.2. Adept Roll also leads on update cadence (every 3 days vs monthly) and ratings volume (205 vs 49). STL Master's advantage is in-app purchases (none vs 3) and device support (4 vs 2). On price, review sentiment and ads there is nothing between them.
