# RSL vs Copeland Mobile

Copeland Mobile's advantage is ratings volume (5.2K vs 1) and update cadence (every 4 weeks vs every 4 months). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
