Granuléo
Read full descriptionHide full description
112 bags left, which is 247 days of heating. That is the first thing Granuléo shows you. No more guessing by looking at the pile in the garage: the app counts what your stove actually burned, what you bought, and what the season has cost you. THREE MOMENTS WHEN IT MATTERS A Sunday evening in January, three bags left, and your supplier is closed until Tuesday. With autonomy in days, you saw it coming two weeks earlier and the pallet was already ordered. You have just installed your stove and you have no idea how much to order for the winter. From your first weeks, Granuléo gives you your consumption month by month, so you order on your own figures instead of a guess. Last winter felt longer. Granuléo puts the current season next to the previous one, month by month, so you can see whether you really burn more or whether it was just an impression. WHAT THE APP DOES Your stock is shown in bags and in kilos, with a gauge and an autonomy in days calculated from your real consumption, not from a theoretical average. Average season consumption is shown in bags per day, with the last seven days in view and the month-by-month trend in the statistics. Bags bought and total spending are tracked across the whole season, based on what you actually paid. The history keeps every bag poured and every purchase at the date you logged it, and filters by type of entry. Granuléo does not connect to your stove: you log, the app calculates. It therefore works with any brand and any model of pellet stove, whether MCZ, Palazzetti, Piazzetta, Edilkamin, Ravelli, Harman, Extraflame, Rika or another. WHAT IS FREE, AND WHAT IS NOT Free, with no advertising: stock, consumption, autonomy and stock end date, month-by-month season consumption and one bag type. As a one-time purchase, with no subscription: multiple bag types; cleaning and annual servicing tracking, with the overdue days shown; four-week and season views, plus five more charts (spending, intensity, cumulative, bag split, price trend); CSV and Excel import and export; and the assistant that answers your questions from your own data and your stove manual. Available in English, French, German and Italian.

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. 27 languages: French, English, German, Italian, Spanish, Portuguese, Japanese, Korean, Swedish, Polish, Dutch, Danish, Finnish, Hindi, Arabic, Chinese, Indonesian, Vietnamese, Thai, Turkish, Norwegian, Czech, Romanian, Hungarian, Greek, Ukrainian and Russian. Kilograms or pounds. EUR, USD, GBP, CHF, CAD.
