# TanLines vs Tanning Tracker

The clearest difference is monetization model: Tanning Tracker at free with in-app purchases against TanLines's subscription. Tanning Tracker also leads on update cadence (weekly vs every 2 months). TanLines's advantage is rating (4.6 vs 4.2) and ratings volume (42 vs 5). On price, ads and in-app purchases there is nothing between them.

Both are free to download. TanLines sells 5 in-app purchases, starting at $6.99 per month and Tanning Tracker sells 8 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

TanLines holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: TanLines has 42 ratings behind it against 5, so its average is the more settled of the two.

TanLines ships an update every 2 months, Tanning Tracker weekly. Both last shipped on November 5, 2026.
