Nenpico

Just log your fill-ups — Nenpico turns them into clear fuel economy and spending insights. Everything stays on your iPhone. No accounts, no ads, no tracking.

Nenpico is a beautifully simple fuel economy tracker. Log your fill-ups and watch your car's real fuel economy come into focus.

EASY LOGGING • Just three fields: odometer, volume, and total paid (unit price is derived automatically) • Ordered the way you read a receipt • Shows your previous odometer reading and the distance driven as you type • Catches typos before they happen: backwards odometer readings and implausible economy values are flagged before saving

ACCURATE BY DESIGN • Full-tank method for accurate average economy • Partial fill-ups are handled correctly • Suspicious entries are excluded from your averages automatically, so one typo never poisons your stats

BEAUTIFUL STATISTICS • Fuel economy trend, unit price trend, and monthly spending charts • Filter by this month, this year, or all time • Cost per km/mi computed automatically

MAKE IT YOURS • Give each car its own theme color — the whole app follows • Add a photo and your home screen becomes your car's dashboard • Manage multiple cars, switch with one tap

YOUR DATA IS YOURS • Export everything to CSV anytime • Nenpico collects no data. Every record lives only on your iPhone • No accounts, no ads, no analytics

Fuel economy tracking that makes you look forward to your next fill-up.
