# EchoRef vs ABA Go

The clearest difference is review sentiment: EchoRef at 100% against ABA Go's 13%. EchoRef also leads on rating (4.9 vs 2.2) and monetization model (free vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

EchoRef holds the better App Store score, 4.9 against 2.2.
