Drink tracker app: how to pick one and use it to drink less
A drink tracker app lets you log each drink as you have it, then shows your week in standard drinks, dry days, calories and money. The best one for drinking less counts in US standard drinks (not UK units or glasses), takes under 10 seconds to log, records when and why you drank, and shows a weekly total against a goal you set. Free options exist, and a note on your phone works too, if you use it every time.
Below: what to log, what features matter and which don't, free trackers and what each one counts, whether tracking actually helps people drink less, how to use a tracker for your first four weeks, and what to check about privacy before you start.
Why track your drinks at all?
Most people underestimate what they drink. Not because they're hiding it, but because pours at home are bigger than a standard drink, drinks bought by others don't feel like yours, and a Tuesday glass is forgotten by Sunday. A tracker replaces the guess with a number.
Counting is also the first step in almost every plan to cut back. NIAAA's Rethinking Drinking site, from the US National Institute on Alcohol Abuse and Alcoholism, suggests keeping track of every drink, and our own guide to how to cut back on drinking alcohol starts with a counting week for the same reason: you can't set a goal you can keep until you know where you start.
Does tracking your drinks actually help?
The evidence says it helps a little on average, and it's cheap. A 2017 Cochrane review (Kaner and colleagues) pooled trials of personalized digital tools, such as apps and websites that give feedback on drinking, for people drinking at risky levels. It found moderate-quality evidence that people using them drank less than people who got nothing, by an average of roughly one to three UK standard drinks a week, for up to six months. The effect was small and varied a lot between studies.
Two honest points follow from that:
- A tracker is a tool, not a plan. Logging tells you what happened. The change comes from what you do with it: a weekly number, dry days, and a different routine at the moment you usually pour.
- It works when you keep using it. Many people log carefully for a week, then miss a Friday, then stop. The best tracker is the one that's quick enough that you never skip it.
What a drink tracker should log
A good log has four parts. Most apps only ask for the first, so add the others in a note field if yours has one.
| What to log | Example | Why it matters |
|---|---|---|
| What and how much | Red wine, 8 oz, 13.5% | Turns the glass into standard drinks; big pours and strong beers hide alcohol |
| When | Thursday, 6:40 p.m. | Shows your drinking days and hours, and whether your first drink is getting earlier |
| Where and with whom | Kitchen, alone | Shows the places and people your drinks go with |
| What happened just before | Got home, hard day, started cooking | Shows your cue: the moment that sets the drink off. This is what you'll change |
The last column is the one that changes things. After two weeks, most people find one or two cues cover most of their drinks: getting home from work, cooking dinner, the kids in bed, Friday with friends. A cue you can name is a cue you can plan a different routine for.
US standard drinks vs UK units: the trap in many apps
Many of the best-known free trackers come from UK and Irish charities, and they count in UK units, not US standard drinks. The two are very different sizes:
| Measure | Pure alcohol | Example |
|---|---|---|
| 1 US standard drink (NIAAA) | 14 g | 12 oz beer at 5%, 5 oz wine at 12%, 1.5 oz spirits at 40% |
| 1 UK unit (NHS) | 8 g (10 ml) | About half a pint of ordinary beer, or a single 25 ml shot |
One US standard drink is about 1.75 UK units. So a UK app that shows "14 units this week" means about 8 US drinks, and the UK low-risk line of 14 units a week is not the same as the US figure of 14 drinks a week for men. If you use a UK app, compare your total with UK guidance, or convert it before comparing with US numbers. Our guide to how many drinks a week is normal explains the US lines.
Some apps count neither: they count glasses or "drinks" without asking the size. A review of the Less app by Healthify, New Zealand's health information site, notes it doesn't use standard drinks, so you have to enter your drinks carefully yourself. Glass-counting is fine for spotting patterns, but it will undercount big pours.
Features that matter, and ones that don't
| Feature | Worth having? | Why |
|---|---|---|
| Logging in under 10 seconds, with your usual drinks saved | Yes, most important | Slow logging is why people stop |
| Drink size and strength (% ABV) per drink | Yes | Converts any pour into standard drinks |
| A weekly total against a weekly goal | Yes | The week is the unit that matters for health guidance and for habits |
| Dry days, planned in advance | Yes | Named dry days are easier to keep than "three days a week" |
| A note per drink (where, why) | Yes | Finds your cue |
| Calories and money | Nice to have | Good motivation; many people are surprised by the monthly figure |
| Streaks and badges | Depends | Motivating for some; a broken streak makes others give up |
| Blood alcohol (BAC) estimate | No, for cutting back | An estimate from weight and time; never use it to decide whether you can drive |
| Export or delete your data | Yes | It's health data; you should be able to take it or remove it |
Free drink trackers and what they count
A few well-known free options, from their own pages and app store listings as of November 2026. Features change, so check the store before you rely on one.
- Try Dry (Alcohol Change UK, the charity behind Dry January). Free, no ads, funded by the charity. Logs drinks and dry days, shows units, calories and money saved, lets you set goals, and tracks sleep, mood and cravings. You don't have to be alcohol-free to use it. Counts in UK units.
- MyDrinkaware (Drinkaware, UK). Free. Tracks your drinks, works out units and calories, and lets you set goals. Built for UK units and UK guidance.
- Less. Free and ad-free according to Healthify's review, aimed at casual drinkers who want to cut down, with daily and weekly limits and a sailing-boat display that reacts to how much you log. Doesn't count in standard drinks.
- NIAAA's online calculators (Rethinking Drinking). Not an app, but free and in US standard drinks: a drink size calculator for any glass and strength, a cocktail calculator, and calorie and spending calculators. Useful alongside any tracker that counts glasses.
- Your phone's notes app or a paper card. Free, private, and works in any unit. Write the date, the drink and size, the time and the moment before. Add it up on Sunday.
Some trackers are part of a paid plan that adds daily lessons or coaching. Our own 30-day plan has a drink tracker built in, counted in US standard drinks and tied to a lesson for your main cue. Whatever you pick, the steps below are the same.
How to use a drink tracker for your first four weeks
| Week | What to do in the app | What to look at on Sunday |
|---|---|---|
| 1: count | Log every drink with size, strength, time and the moment before. Change nothing | Your weekly total in standard drinks; your drinking days; your top one or two cues |
| 2: set a goal | Set a weekly goal about a quarter to a third below week 1. Mark two dry days by name | Did you hit the goal? Which day went over, and what was the cue? |
| 3: change one routine | Keep logging. At your main cue, try a swap (a walk, a shower, a cold sparkling drink in your usual glass) | Drinks at that cue this week versus week 1 |
| 4: set your rules | Lower the goal a little if week 3 felt easy. Add a daily cap | Your four-week trend. Keep the rules that worked |
Three habits make logging stick:
- Log when you pour, not later. End-of-night logging is a guess. Logging at the moment also gives you a second to decide.
- Put the app where the drinks are. On your home screen, in the same place you'd see it at your cue time.
- Look every Sunday. Five minutes: the total, the days, the cues, next week's goal. The weekly look is where the change happens.
If you'd rather start from the cue than from a week of counting, the free drinking pattern quiz asks when, where and why you usually drink and names the pattern behind most of your drinks in 2 minutes.
Privacy: what to check before you log
A drink log is sensitive health information. Before you start, take two minutes with the app's privacy page and store listing:
- Does it need an account? An app that works without one keeps less about you.
- Is your log shared or sold? The App Store's privacy label and Google Play's data safety section show what data is collected and whether it's linked to you or used for tracking.
- Can you export and delete? You should be able to download your history and delete your account.
- Is it a health service? Most consumer apps aren't covered by the privacy rules that apply to your doctor's records, so assume what you log is only as private as the company makes it.
If none of that sits right with you, a paper card or your phone's notes works just as well.
Mistakes people make with drink trackers
- Logging glasses, not standard drinks. Nine 8 oz glasses of wine is about 14 drinks, not 9.
- Mixing up units. Comparing a UK-unit total with US limits makes your week look nearly twice as heavy as it is, or the reverse.
- Skipping the bad nights. The nights you don't want to log are the ones with the most to teach you.
- Only logging the drink. Without the time and the moment before, you have a total but no idea what to change.
- Quitting the app after a missed day. Log what you remember and carry on. A gap is fine; stopping isn't.
- Treating the app as the plan. Tracking shows the problem; the routine change at your cue solves it.
When a tracker isn't enough
If your log shows you often drink much more than you planned, you've tried to cut back several times and can't, or you feel shaky, sweaty or anxious when you go without, talk to a doctor. Cutting down quickly after heavy daily drinking can bring on withdrawal, which can be dangerous. The NIAAA Alcohol Treatment Navigator explains the options, and SAMHSA's free, confidential helpline answers any time on 1-800-662-4357. Many trackers, including the Less app according to Healthify, say plainly they aren't designed for alcohol addiction.
Questions people ask
What is the best free app to track alcohol?
The best one is the one you'll use every time you drink. In the US, check that it counts in US standard drinks or lets you enter size and strength. Try Dry and MyDrinkaware are free and well made but count UK units; a phone note works in any unit.
Is there a drink tracker app that counts US standard drinks?
Some do; check the settings for "standard drinks" and a US option, or whether you can enter the size in ounces and the % ABV. If an app only counts glasses, use NIAAA's drink size calculator for your usual pour once, then log that number.
How do I count a drink in an app if I don't know the size?
Measure your usual glass once at home with a measuring cup, filled to where you normally pour. Save that as your default drink. At bars, assume a pint is about 1.3 drinks and a cocktail about 2.
Can an app help me drink less without quitting?
Yes, that's what most drink trackers are built for. Research on digital tools found a small average drop in drinking. The bigger change comes when you pair the log with a weekly goal, dry days and a new routine at your main cue.
Should I track dry days or drinks?
Both. Dry days are easy to see and celebrate; the weekly drink total tells you whether the days you do drink are getting lighter.
Is a BAC app accurate?
No app can measure your blood alcohol; it estimates from your weight, sex, drinks and time. Never use one to decide whether you can drive. After drinking, don't drive.
Know your cue before you count
A tracker shows when you drink; the free drinking pattern quiz shows why. It takes 2 minutes, names the cue behind most of your drinks and shows where a 30-day plan would start.
