Every feature: fuel, consumption, costs and reminders

Fuel

Consumption, worked out between full tanks

A fill-up takes the odometer, the date, the price per unit, the quantity and the total. Fill in two of price, quantity and total and the app works out the third. Once a vehicle has a fill-up on file with both a volume and a sum behind it, the next new entry offers the price from that one and shows how far you have driven since.

Consumption is the figure people get wrong by hand. The app measures the distance between two full tanks of the same fuel and divides by what went in between. Until there are two full tanks to work with, it prints a dash rather than a number.

Consumption is calculated between full fill-ups of the same fuel type. Electric charges always count as full.
In the list of fill-ups, a partial one is shown with a ~ in front of the figure. Partial fill-ups are only taken into the calculation if you switch that on in Settings.
A vehicle set up with two fuels gets a separate consumption figure for each of them.
Read consumption as L/100 km or as distance per unit of volume, whichever you think in. It is a setting, not a fixed choice.

Statistics

Where the money actually goes

Pick a period and the screen answers three questions: how much you spent, what you spent it on, and what a kilometre cost you. The tabs are All time, Current month, Previous month, 3 months and Year; on All time you can also set any two dates yourself. There is no weekly view.

Two things worth knowing. 3 months and Year are windows that end on the last day of the previous month, so the month you are in is not counted in them. And a new vehicle starts with All time alone — the other tabs appear as history builds up, Year after roughly twelve months of records. When a figure cannot be calculated from what you have entered, the app prints a dash instead of a zero.

Price of 1 km for the period, and the same figure counting fuel only.
Number of records, total spent, distance covered, average distance per day, average monthly spending.
A pie chart splits the period by category, and the list under the total shows what each category took.
Charts for spending by month, consumption over time and fuel price over time. Each one saves as an image you can send to someone.

Reminders

What is due, and how far off it is

A reminder carries a vehicle, a name, an expense category, an optional expected amount, a schedule and how far ahead you want warning — in days or in distance. The list hands all of it back: oil and filter change on the daily driver, each 15,000 km starting from 51,619 km, 437 km remaining; liability insurance, once on 14 October, 46 days remaining. A swipe one way marks a reminder done, a swipe the other way postpones it.

None of this needs the server. A background task looks the reminders over on the phone itself and raises the notification there, and a push from the server only makes it arrive sooner when there is a connection. Two channels are used: one for what is already overdue, and a quieter one for what is coming up.

Six schedules, listed under Periodicity: every so many kilometres or miles; every so many months; whichever of those two comes first; a chosen day each month; once at a given odometer reading; once on a given date. The last two happen once and are then finished.
How much warning you get is yours to set — a number of days, or a distance still to run. An expected amount can be filled in as well, and it is optional.
The check is periodic rather than instant: it runs roughly every six hours, so a notification can land some hours after the reminder falls due, and Android battery saving can delay it further.
Notifications appear between 09:00 and 22:00 local time, no more than one every eight hours, and never while the app is open. The buttons on them are Done and Postpone; Postpone silences that reminder until the end of the day, works without a connection, and is not carried to your other devices.

Monthly limits

How much of the month is already gone

A limit is set per vehicle and covers either everything, or one whole expense type, or a single category. Several can run at once: on the screen here, All expenses stands at 57 per cent — 181.76 of 320 EUR, with 138.24 left — and Fuel at 61 per cent, 122.68 of 200 EUR. The same progress appears on the home screen, where the card is not shown at all until a limit exists. Spending in another currency is converted into yours before it counts against the limit.

Limits are held on this phone alone. They are never sent to the server, so a second phone signed into the same account will not show them and reinstalling the app clears them. The other side of that is that they need no connection: unlike almost everything else here, a limit keeps counting while you are offline.

The period is the current calendar month, and only that. There is no weekly limit, no yearly one and no rolling thirty days.
The bar turns orange at 80 per cent of the limit and red once you pass it. Spending exactly the limit is not yet passing it.
A limit set on the whole vehicle can also notify you — once at 80 per cent and once when it is exceeded, at most once per vehicle per calendar month, and only if you are signed in with notifications allowed.
A limit set on a single expense type or category shows its colour on the screen and sends nothing. If you want to be told, the limit has to be the one on the whole vehicle.

Year in numbers

What the year cost, against the one before

One screen for the whole year: distance, litres, money, how many records you made, the breakdown by category and the most expensive fill-up. At the foot of it, the same total set against last year, as a percentage up or down.

For a year still running, both years are cut off on the same calendar day, so the comparison is like for like — on 29 August it weighs January to August against January to August. The screen lives in the overflow menu on Statistics, and it saves as an image if you want to send it to someone.

Distance, fuel, money spent and number of records for the year.
Spending broken down by category, from fuel down to the small stuff.
The most expensive fill-up of the year, with its date.
Compared with last year: total spending, both years cut off on the same calendar day, with the difference as a percentage. If there is no previous year to compare against, the line is not shown at all.

Appearance

Six colour themes plus Follow system

The default is Follow system, so on Android 10 and newer the app goes dark when the phone does. You can pin a fixed theme instead at any time: Light, Dark, Triad, Neutral Light or Neutral Dark. Three of them are always dark and two are always light — those ignore the system setting entirely.

Material You is offered on Android 12 and newer, where the device supports it, and the app then takes its colours from your wallpaper. The new colours appear at the next cold start, not the moment you pick the theme. The screenshot here is the home screen with the phone switched to night mode.

Changing the theme changes the app only. It does not touch the system dark mode.
The default theme's accent is a deep blue. The green on this site is the app's mark: the icon, the splash screen and the first-run screens.
The app ships no fonts of its own. Text is set in your phone's own system font.

The smaller things

Details you only notice when they are missing.

Six vehicle types

Car, truck, motorcycle, scooter, boat and other, each with its make, model, year, engine size, tank sizes and odometer — plus plate number and VIN if you want them recorded.

Two fuels on one vehicle

Petrol, diesel, gas (LPG or CNG), electric, hydrogen or other. A vehicle can be set up with two of them, and the expense form then offers only those two.

Units chosen separately

Distance in kilometres or miles; volume in litres, UK gallons or US gallons. They are two independent settings, not one metric-or-imperial switch.

Your own categories

Nine built-in types — fuel, service maintenance, insurance, lease, spare parts, taxes, parking, fees, other — and your own subcategories under any of them.

Expense templates

Save a filled-in form as a template and reuse it from Quick entry on the home screen. Templates sort themselves by how often you use them, and they carry no odometer reading or date.

Export to CSV and PDF

One vehicle at a time, handed to whatever app you pick from the share sheet. The CSV carries the vehicle, the all-time summary and every record; the PDF is a report, and its table leaves out records ticked Exclude from statistics.

A comment on any record

Free text on every expense, so what the money was actually for is attached to the number and not remembered wrongly six months later.

Boats in nautical miles

Pick Boat as the vehicle type and distances are shown in nmi — on screen, in the CSV and in the PDF. The kilometre-to-mile conversion is not applied to boats at all.

Units and currencies

Distance and volume are two separate settings, so kilometres with US gallons is as valid a combination as miles with litres. Consumption follows from them: L/100 km, or distance per unit of volume if that is how you read it. Boats are the exception to all of it — their distances are measured in nautical miles, and the kilometre-to-mile conversion is never applied to them.

More than 160 currencies. Enter an expense in the currency you actually paid in. Totals, statistics and limits are then converted into your own currency at the rate the app holds for that currency — not the rate that applied on the day you spent it. Rates reach the app from the MiExpenses server, which refreshes them once a day from the European Central Bank feed and, where it is configured, a commercial rates provider. The app itself never talks to a rates provider. Not every currency is quoted, so some are never refreshed.

Sharing a vehicle with someone else

You can give another registered user access to a vehicle by e-mail, at one of three levels: View, Edit, or Move ownership. It is the whole vehicle or nothing — every record attached to it goes with it, and individual records cannot be held back.

Once they accept, they get the vehicle, all of its expenses and reminders, including entries made by other people it is shared with, and a copy of your expense categories. On View they can only read: the fields are not editable and there is no save or delete. On Edit they can add expenses and reminders, and change or delete only the ones they created themselves — the server checks that, not just the buttons in the app. Move ownership is permanent: you set a PIN, they type it, the vehicle and everything on it becomes theirs, and you are left with View. There is no undo.

The invitation only takes effect for the other person once they accept it. Before that the vehicle is hidden in their app — but their device has already downloaded and stored the vehicle and its records.
Revoking access immediately removes the vehicle from the other person's app and blocks any further changes by them.
Moving ownership asks for a PIN of at least four digits, which the other person types to confirm. Treat it as a handover step, not as protection.

What is stored, where it goes and who can see it is set out in the privacy policy.
