Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Jet Fueling
This app assists aircraft refueling operations and payload calculations. It helps determine desired bloc fuel, computes uplift quantities considering various factors, and performs basic fuel and specific gravity conversions. A built-in calculator is accessible via a swipe gesture.
- Payload vs. Bloc Fuel determination
- Uplift quantity calculation
- Fuel on Board (FOB) consideration

"Jet Fueling" can be used by anyone involved in the process of refueling an Aircraft, and/or determining Payload in regards to Bloc Fuel and vice-versa. The first tab: "LIMITATIONS" allows to fine-tune available paylod versus desired Bloc Fuel and vice-versa... Desired bloc fuel is computed on this tab. The second tab: "REFUEL", helps compute the quantity needed to be uplifted (in Liters, US Gallons or ImpG) taking into account: - The desired quantity upon departure (Bloc), - The remaining fuel on board at the time of the computation (FOB –Fuel On Board -), - The fuel consumption of an APU or other power unit until departure, - And of course Fuel density (specific gravity for the purists). It also allows for some basic conversions (ex: USg to Lbs, L to kg etc…) as well as specific gravity conversions. On both these tabs, a basic calculator can be summoned by a swipe gesture. It is dismissed in the same way.
M.E.L.C.
This tool helps aircraft engineers calculate the expiration dates for airplane defects based on minimum equipment lists. It provides a clear overview of all critical dates and allows for customization of defect categories.
- Calculate defect expiration dates
- Supports categories A, B, C, D
- View all important dates at a glance
- Customize defect categories

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
