Which fuel app should you actually use?
I make one of these, so read this knowing that. I've tried to write the page I wanted when I was choosing, which means saying plainly where the others beat mine.
Start here, if you want the short version
Hate subscriptions? Buy Road Trip MPG. It's $6.99 once and there's no in-app purchase at all. It also has the highest rating of anything in this category — 4.90 from 625 ratings — which is not an accident.
Want a community and a website? Use Fuelly. Over 29,000 ratings and a web service where you can see what other people with your car are getting. I have neither of those things and I'm not going to have them any time soon.
Everything's fine and you just want to log fill-ups? Any of them will do. Genuinely. If you always fill the tank to the brim and you don't care where your data lives, this is a solved problem and you should pick whichever icon you like.
FuelJot is worth a look if one of these three things bothers you: your fill-ups aren't consistent, you'd rather your records didn't live on someone's server, or you want to be certain you can take your history elsewhere later.
Prices
I pulled these from the App Store listings in August 2026. Prices change — check before you take my word for it.
| App | What it costs | Rating | Ratings |
|---|---|---|---|
| Fuelly | $7.99/yr or $0.99/mo. Free version carries ads | 4.74 | 29,374 |
| My Car | $10.99/yr or $1.49/mo, plus 5 business tiers | 4.70 | 1,143 |
| Drivvo | 7 tiers, $5.99 to $49.90/yr | 4.68 | 952 |
| Car Cave | $4.99 once | 4.67 | 351 |
| Fuelio | $17.99/yr or $4.99/mo | 4.49 | 142 |
| Fuel Tracker | 6 tiers, $0.99 to $24.99 | 4.45 | 611 |
| Fuel Monitor Pro | $1.99/yr — plus $49.99 to export your own data | 4.42 | 827 |
| Road Trip MPG | $6.99 once, no in-app purchases | 4.90 | 625 |
| FuelJot | $4.99 once, no subscription. Export always free | — | none yet |
That $49.99 line isn't a typo. Fuel Monitor Pro sells a $1.99 yearly subscription and then charges $49.99 as a separate purchase to let you export the records you typed in yourself. I mention it every chance I get, and it's the reason FuelJot's export will never be behind a paywall.
The differences that actually matter
Partial fill-ups
This is the one I built the app around. Most fuel apps have a single "fill-up" entry and quietly assume the tank ended up full. If you top up half a tank on a Wednesday, the number they give you afterwards is wrong, and nothing on screen tells you so.
FuelJot asks how you filled up — full tank, low-fuel light, or neither — and keeps the first two in separate chains that never mix. The third doesn't produce a figure at all; that fuel carries forward to the next real anchor.
Several of the apps above do handle partial fills to some degree. None of the ones I tried keep low-fuel-light fills as their own consistent baseline, which matters if that's how you actually drive.
Where your data lives
Fuelly and Fuelio are built around a web account, which is exactly why Fuelly's community works. The trade-off is that your history lives on their servers.
FuelJot has no server. That's not a security claim I'm asking you to trust — the app contains no networking code, so there's nowhere for anything to go. It also means no community, no sync between your own devices, and no web view of your data. Those are real things to give up.
Getting your data out
CSV import and export in FuelJot are free and always will be. You can leave whenever you want and I'd rather you could.
A fuel log is only useful because it covers years. If the app holding it disappears, those years go with it — which is worth thinking about before you commit five years of records to anything, mine included.
Everything side by side
| FuelJot | Fuelly | Road Trip MPG | Fuel Monitor Pro | |
|---|---|---|---|---|
| Separate chains for full vs low-fuel-light | Yes | No | No | No |
| Ads | Never | In the free version | None | None |
| Account required | No | Yes | No | No |
| Web access | No | Yes | No | No |
| Community | No | Large | No | No |
| CSV export | Free | Via the website | Yes | $49.99 |
| Cost | $4.99 once | $7.99/yr | $6.99 once | $1.99/yr |
| Track record | None. It's new. | Years | Years | Years |
One more thing about Fuelly
Fuelly is the app most people in this category are already using, so it's worth being precise rather than snide about it.
The iOS app was last updated in June 2024. Since May 2025 the team have said on their own forum, more than once, that a rewrite is coming. It hasn't shipped yet. Some people are waiting for it; others have gone looking for something else, which may be how you got here.
If you're in the second group, I've written up how to get your records out of Fuelly and into something else — including apps that aren't mine.
