# Tuner Assist vs OBDocker

The clearest difference is rating: OBDocker at 3.9 against Tuner Assist's 3.0. OBDocker also leads on ratings volume (17 vs 2). Tuner Assist's advantage is monetization model (free vs freemium) and iOS requirement (8.0 vs 13.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Tuner Assist sells 2 one-off in-app purchases and OBDocker sells 7 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

OBDocker holds the better App Store score, 3.9 against 3.0.
