Log what you drank in a few taps. The units are worked out for you.
Search by brand, pick the size you actually had, and the units and calories are calculated from the real strength of that product. No sums, no guessing at an average, no working out what a large glass of 13% comes to at half past eleven at night.

Why this exists
Nobody keeps an accurate running total in their head
The reason people underestimate their drinking is not dishonesty. It is arithmetic. A glass at home on Tuesday, two pints on Thursday and a bottle shared on Saturday are three separate events that never get added together, and the strengths are all different. Writing each one down at the time is the only thing that produces a real number.
- A pint of 4% lager and a pint of 5.6% craft beer are not the same drink
- Home measures of spirits run at roughly double a pub single
- A 250ml glass of wine is a third of a bottle, not a quarter
- Rounds and top-ups are the entries most often forgotten
How it works
Using drink logging
Find what you drank
Type a brand name and pick it from the list. The catalogue holds more than 2,400 UK products with the strength printed on the label. If yours is not there, add it once and it is yours from then on.
Pick the serving
Standard UK measures are already set up: a pint, a half, a 175ml or 250ml glass, a 25ml or 50ml single, a bottle, a can. Or enter the millilitres if you poured it yourself.
Set the day and time
It defaults to now. Change it to any date if you are catching up on a day you missed, and the entry lands in the right week for every chart and total.
The total updates
Your day, your week, your running average and your goal all move the moment you save. Nothing needs recalculating and nothing waits until tomorrow.
What you get
In the app
2,400 branded products
Beers, lagers, ciders, wines, spirits, ready-mixed drinks and low and no alcohol options, each with the ABV from the label rather than a category average.
UK units, done properly
Volume in millilitres multiplied by ABV, divided by 1000. One unit is 10ml of pure alcohol. The same sum sits behind every figure in the app.
Back-date anything
Missed a few days? Add them. A record with the awkward days filled in is worth more than a tidy one with holes.
Calories alongside units
Alcohol carries roughly seven calories a gram and most people have never counted them. They are recorded next to the units so you can see both.
Who this helps
What it changes
If you are not sure whether you have a problem
A fortnight of honest entries answers the question better than any quiz. Most people are surprised by their own weekly total, not because they were hiding it but because they had never added it up.
If you are cutting down
You cannot reduce a number you do not know. Logging gives you the starting figure everything else is measured against.
If a GP has asked how much you drink
Turning up with a fortnight of dated entries changes the conversation completely. It moves from an estimate you feel judged on to a record you can both look at.
Being straight with you
A day you did not log is not a day you did not drink
Alcohol-3 will not quietly fill a gap with a zero. Untracked days are shown as untracked, and they do not count towards your alcohol-free days or your streak. A number that flatters you is no use to you.
Common questions
How are alcohol units calculated?
Units are the volume of the drink in millilitres multiplied by its ABV percentage, divided by 1000. A 568ml pint of 4% lager is 568 times 4 divided by 1000, which is 2.3 units. One UK unit is 10ml of pure alcohol.
What if my drink is not in the catalogue?
Add it with its name, strength and the serving you have. It is saved to your account and appears in your own list from then on, so you only do it once.
Can I log a drink for a day that has already passed?
Yes. Any entry can be back-dated to any date, and every chart, average and goal recalculates to include it.
Is drink logging free?
Yes. Logging, the catalogue, the charts and the calendar are all part of the free account. There is no limit on how many drinks you record.
