# Jet Fueling vs M.E.L.C.

The clearest difference is price: M.E.L.C. at Free against Jet Fueling's $1.99. M.E.L.C. also leads on rating (5.0 vs 4.6). Jet Fueling's advantage is update cadence (monthly vs every 18 months) and review sentiment (89% vs 75%). On ads, in-app purchases and device support there is nothing between them.

M.E.L.C. is free to download; Jet Fueling costs $1.99 up front. Jet Fueling sells 1 one-off in-app purchase and M.E.L.C. sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

M.E.L.C. holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Jet Fueling has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 89% of Jet Fueling's written reviews are positive against 75% of M.E.L.C.'s, so the app with the better star average is not the one people write more warmly about.

Jet Fueling ships an update monthly, M.E.L.C. every 18 months. The most recent releases landed on October 31, 2026 and November 4, 2026 respectively.
