# Mares App vs Digidive

The clearest difference is review sentiment: Digidive at 100% against Mares App's 47%. Digidive also leads on rating (5.0 vs 4.5). Mares App's advantage is ratings volume (183 vs 33). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Mares App sells 8 in-app purchases, starting at $2.99 per month and Digidive sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
