Know how much gas is left in your propane bottle before the barbecue goes out. What it does • Reads your ultrasonic tank level sensor live, with no pairing and no account • Shows the level as a percentage on a bottle gauge you read at a glance • Choose your bottle once from the home screen: 20, 30 or 40 lb cylinders, 6, 11 or 14 kg bottles, or any tank by its height • Charts of the level, with the lowest, average and highest value • A low-level alert on each bottle • The last value and when it was heard, even when the sensor is out of range • A home screen widget with your bottle's level • Horizontal tanks too, flat or rounded ends, from presets or your own dimensions • Light and dark themes that follow your phone, and layouts made for tablets and foldables Why it is different The bottle you use leads the screen, and Pro tells you how many days of gas are left at this week's pace, so a refill is planned instead of discovered mid-cook. The app never asks for your location. Included for everyone Every sensor live, the bottle gauge, the last 24 hours, and alerts while the app is open.
