# Opalite vs Slime

The clearest difference is in-app purchases: Opalite at none against Slime's 3. Opalite also leads on update cadence (every 5 days vs every 11 days) and ratings volume (6 vs 1). On price, rating, ads and device support there is nothing between them.

Both are free to download. Slime sells 3 in-app purchases, starting at $9.99 per month. Opalite asks for nothing beyond the download.
