Verdict
The clearest difference is rating: TNMaker at 4.0 against SMAS's 1.8. TNMaker also leads on update cadence (weekly vs monthly) and ratings volume (27 vs 5). SMAS's advantage is in-app purchases (none vs 5) and iOS requirement (11.0 vs 15.0). On price, review sentiment, ads and device support there is nothing between them.
