# memoryOS vs bikablo

The clearest difference is rating: memoryOS at 4.9 against bikablo's 1.0. memoryOS also leads on review sentiment (80% vs 44%) and update cadence (every 3 weeks vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. memoryOS sells 20 in-app purchases, starting at $3.99 per 7 days and bikablo sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
