# TankData vs Bark

The clearest difference is review sentiment: TankData at 100% against Bark's 13%. TankData also leads on in-app purchases (none vs 4). Bark's advantage is rating (4.2 vs 3.0) and ratings volume (35K vs 4). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Bark sells 4 in-app purchases, starting at $5.99 per month. TankData asks for nothing beyond the download.

Bark holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Bark has 35K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of TankData's written reviews are positive against 13% of Bark's, so the app with the better star average is not the one people write more warmly about.

TankData ships an update every 4 months, Bark every 2 months. The most recent releases landed on June 6, 2026 and September 25, 2026 respectively.
