1. 1

   Gas

   The cylinder gauge with days of gas left, the book-by pill, what's on the stove and your learned burn rate.

2. 2

   Refills

   Every cylinder you have taken, with its status, price, subsidy and how many days it lasted.

3. 3

   Cylinder detail

   One cycle end to end: booked, delivered, on-stove, emptied, delivery lag, price, subsidy, net cost and cost per day.

4. 4

   Log a refill

   Delivered and booked dates, price, subsidy, cylinder size, put-on-stove and close-the-previous-cylinder toggles.

5. 5

   When to book

   The step-down plan from predicted empty to book-by, the eligibility window under the gap rule, and Mark as booked.

6. 6

   Gas ledger

   Spent, subsidy back and net cost over twelve months, a month-by-month bar chart and every refill with its net.

7. 7

   Burn rate

   Your kg-per-day figure, how many days each cylinder lasted, the household-size fallback and how the prediction works.

8. 8

   Cylinder rotation

   The stove cylinder and the reserve side by side, a one-tap swap and the swap history.

9. 9

   Short-fill check

   Burn rate per cylinder against your normal band, with the flagged cylinders and what to tell the agency.

10. 10

    Your connection

    Name, gas company, cylinder size, household size, double-cylinder, dealer, booking-gap rule and delivery-lag override.

11. 11

    Settings

    Safety buffer, nudge window, connection shortcuts, backup export, sample data and erase.

Try it with sample data: Loads a four-person Indane kitchen on 14.2 kg cylinders with eight refills over the last six months — one on the stove, one in reserve, three logged swaps, and a cylinder that emptied fast enough to trip the short-fill flag. You can start fresh at any time.
