# BitDynamic vs ConTutor

The clearest difference is in-app purchases: ConTutor at none against BitDynamic's 10. ConTutor also leads on review sentiment (50% vs 29%). BitDynamic's advantage is ratings volume (6.1K vs 5). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. BitDynamic sells 10 in-app purchases, starting at $19.99 per month. ConTutor asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.3 for BitDynamic against 4.2 for ConTutor.
