# MP4 Maker vs Chatrobotics App

The clearest difference is rating: Chatrobotics App at 5.0 against MP4 Maker's 4.6. MP4 Maker's advantage is ratings volume (2.4K vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. MP4 Maker sells 1 one-off in-app purchase and Chatrobotics App sells 5 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Chatrobotics App holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: MP4 Maker has 2.4K ratings behind it against 1, so its average is the more settled of the two.
