What happened to Fuelly
Fuelly earned its following honestly: a beloved fuel log with a genuinely unique asset — community MPG benchmarking against the fuelly.com database, so you could compare your real consumption with thousands of identical cars. Many users ran it for years and valued it as a maintenance record with receipt photos, not just a gas log.
But as of mid-2026, the iOS app's last update was June 3, 2024 — two years of silence. Reviews document a forced-login update that cost users local data ("all my data is gone" stories, with support unresponsive), and its sibling Android app aCar fared worse after the acquisition era: forced account migrations, a paid ad-free unlock retroactively limited to two years, and a rating that collapsed to 1.74★. None of this means Fuelly can't still work today — it means betting the next decade of your car's history on it is a risk you can now see clearly.
First, get your data out (do this regardless)
Fuelly supports CSV export — use it now, even if you're staying. An export costs two minutes and converts "years of my history live inside a stagnant app" into "I hold a portable copy." Export from the website or app, and you'll have your fill-ups and service entries as a plain CSV file that any tool — including a spreadsheet — can read.
That, incidentally, is the test to apply to whatever you choose next: if an app doesn't offer free, unconditional export, your data is collateral. The angriest reviews in this category are not about features — they're about people locked out of records they spent years building, by forced logins, broken sync, or abandoned apps.
What to look for in the next app
Fuelly's story suggests three criteria beyond features. Durability: local-first storage means the app's fate doesn't decide your data's fate — records on your device keep working even if the developer vanishes. Honest economics: a one-time price or a genuinely usable free tier ages better than a subscription meter on your own records. Exit rights: free export, always.
Odobook is built on exactly those three: records stored on your device (no account needed, fully offline), free tier with one vehicle, unlimited records, reminders, and fuel stats with real MPG calculation from your fill-ups — no ads ever — and CSV export free for everyone. Pro is $9.99 once, adding unlimited vehicles, receipt photos, custom categories, the PDF service history report, and CSV import that accepts Fuelly's export format, so your history continues in one unbroken line.
Fair warning about what you'd give up: Fuelly's community MPG benchmarking has no equivalent in Odobook — comparing your consumption against the crowd was Fuelly's special trick, and we don't pretend to replace it. What you gain is a log that can't be taken hostage.
