# Carista OBD2 vs RepairSolutions2

The clearest difference is review sentiment: RepairSolutions2 at 96% against Carista OBD2's 34%. RepairSolutions2 also leads on ads (none vs shown) and rating (4.8 vs 4.6). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Carista OBD2 sells 6 in-app purchases, starting at $19.99 per month and RepairSolutions2 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
