TankFiller
A consumer app that tells drivers and homeowners when to fill up or top off the oil tank, using live regional fuel prices, local heating-oil delivery costs, and a simple forecast of where prices are heading over the next 2 weeks.

- Cheapest-station finder with a 'price likely to rise this week' flag so users know when to fill up now
- Heating-oil price tracker with a top-up reminder when your regional average drops below your personal threshold
- Plain-language 'why prices moved' digest (e.g. 'Red Sea tanker attack pushed wholesale prices up 2%')
- Tank-size and consumption-based calculator that estimates next refuel date and total yearly cost
