Fresh goes down, waste goes up, the cassette fills, and memory is a terrible gauge for any of them. The gas empties too, and the leisure battery does whatever the weather lets it. Stops & Stays gives every system a proper reading, logged with the stop.
Two readings, not one
Each stop records levels twice: the state you arrived in and the state you left in. That pair is the whole trick. A single snapshot tells you what you had; the pair tells you what the stop did: how much water two nights off-grid actually used, what a day on hookup put back into the battery, whether the cassette can stretch to one more night.
Over a trip, those pairs become the operating manual for your own van, measured in your own van rather than read off a brochure. Two trips of it and you know your real range between service points, which is the number behind where to fill and where to empty, and how long a leisure battery really lasts in the weather you actually get.
Seven systems, tracked properly
The app covers the lot: fresh water, waste water, toilet cassette, LPG, leisure battery, power station charge and vehicle fuel. Each gets its own arrival and departure state, so the record reads the way you think: water's fine, gas is getting low, battery took a beating under that week of Welsh cloud.
Fuel is on the list too. Range planning in the far north-west is a genuine tank calculation, because between Durness and the next proper pumps there is a lot of scenery and not much else. The fills themselves live in the fuel log; levels record what was in the tank either side of the stop.
Only the systems you actually have
No two vans carry the same kit, so the app doesn't pretend they do. Your vehicle profile has toggles for each system (LPG and its type, leisure battery, power station, toilet, fresh and waste water, tank capacity), and only the systems you switch on ever appear in the UI. A campervan with a power station and no cassette never sees a cassette field. A motorhome with the full set gets the full set.
Run more than one vehicle and each profile keeps its own configuration. The app asks about the van you're driving, not a generic one.
Aire at Wissant, day four in France, fresh water showing about a quarter. The log said the last proper fill was Boulogne, and that a quarter does us one frugal night, not two. We stayed the one night, filled at the borne on the way out, and nobody had to ration the washing up on a guess.
Levels bracket the whole trip too
The same idea scales up. Every trip records initial and final levels alongside its start and end odometer, so a fortnight away is bookended the same way a single stop is: what you set off with, what you came home with. Useful for the post-trip reckoning, and just as useful the night before departure when you want to know whether the gas that's left will survive week one.
A full set of levels goes in at arrival and again before you pull away, with no signal needed. Small habit, and it retires the three questions that nag at every van kitchen: how much water, how much gas, how long before the cassette becomes urgent.
Consumption, not just readings
Two readings a stop is a consumption rate, and a rate is what changes with the seasons. Gas that lasted a fortnight in July will not last a fortnight in January, and the pair of readings shows you that happening rather than leaving you to discover it on a cold Tuesday. If you live in the van rather than holiday in it, that is the difference between guessing at next month and knowing it. How full-timers use the numbers.
