# Fill Up Tracker vs Renogy

The clearest difference is rating: Renogy at 3.8 against Fill Up Tracker's 2.9. Renogy also leads on ratings volume (828 vs 11) and update cadence (every 2 weeks vs every 3 months). Fill Up Tracker's advantage is review sentiment (48% vs 11%) and iOS requirement (8.0 vs 13.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Renogy holds the better App Store score, 3.8 against 2.9. That said, the two scores are not equally well evidenced: Renogy has 828 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 48% of Fill Up Tracker's written reviews are positive against 11% of Renogy's, so the app with the better star average is not the one people write more warmly about.

Fill Up Tracker ships an update every 3 months, Renogy every 2 weeks. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
