Pellio

Pellio is your household heating logbook. You log your refills; the app tells you what is left, how long it will last, and what the season is costing you. THE ONE GESTURE, IN FIFTEEN SECONDS Standing at the appliance, a bag in one hand and the phone in the other: one screen, one field, large buttons. Bags adjust by half a bag, the weight appears at once, and the app tells you what will be left afterwards. WHAT THE APP ANSWERS • Remaining stock, in kilos and in bags • Estimated days left: "about 4 weeks", never a false certainty • Your observed rhythm: "refill expected today" • The last fourteen days at a glance — this is where a forgotten entry shows up • An alert when stock drops below a week, and when your week runs well above your habit YOUR PURCHASES, AND WHAT THEY COST Supplier, date, bags, price per kilo including delivery. Pellio works out your average, your cheapest and your dearest buy, and points out your best time to order based on your history. THE APPLIANCE LOGBOOK Details of your stove, insert or boiler: brand, model, warranty, annual service. A record of every job, from sweeping the flue to replacing the glass. And thresholds in kilos — "clean the burn pot every 300 kg" — with how much is left to burn before it falls due. THE SEASON, CLOSED OUT From 1 September to 31 August: fuel burned, cost, bags carried, first and last day of heating. Share the summary as text, or export it to CSV and PDF. NO ACCOUNT, NO NETWORK, NO ADVERTS No sign-up, no email address. Everything works offline: the garage has no signal, and the app does not need one. Your heating records stay on your phone. No adverts, no subscription. WHAT PELLIO DOES NOT DO It measures nothing: no sensor, no tank gauge. It gives back what you declared, and shows an estimate as an estimate. Data can be backed up by export, then imported back on another phone. 15 languages: French, English, German, Italian, Spanish, Portuguese, Japanese, Korean, Swedish, Polish, Dutch, Danish, Finnish, Hindi and Arabic. Kilograms or pounds. EUR, USD, GBP, CHF, CAD.

Verdict
The clearest difference is in-app purchases: Pellio at none against Granulo's 5. Pellio also leads on ads (none vs shown) and update cadence (every 5 days vs every 3 weeks). On price, device support and iOS requirement there is nothing between them.
