# Fuelly vs DataMan

The clearest difference is price: Fuelly at Free against DataMan's $0.99. Fuelly also leads on rating (4.7 vs 4.4) and ratings volume (30K vs 694). DataMan's advantage is review sentiment (81% vs 59%). On ads, in-app purchases, monetization model and chart position there is nothing between them.

Fuelly is free to download; DataMan costs $0.99 up front. Fuelly sells 2 in-app purchases, starting at $0.99 per month and DataMan sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Fuelly holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Fuelly has 30K ratings behind it against 694, so its average is the more settled of the two. Written reviews complicate that: 59% of Fuelly's written reviews are positive against 81% of DataMan's, so the app with the better star average is not the one people write more warmly about.

Fuelly ships an update every 5 weeks, DataMan every 3 months. Both last shipped on October 25, 2026.
