# REST API Client vs Keylines

The clearest difference is rating: Keylines at 5.0 against REST API Client's 4.3. Keylines also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). REST API Client's advantage is ratings volume (6 vs 1). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. REST API Client sells 1 one-off in-app purchase and Keylines sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Keylines holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: REST API Client has 6 ratings behind it against 1, so its average is the more settled of the two.
