Made for cutting down
GrogLog is for people who want to drink less. It keeps an honest count and puts it where you can see it: today as a running total against yesterday and your usual day, a daily budget that comes down at the pace you set, and a calendar that shows each day as it went.
It is quick because it has to be. Your usual drinks sit on one screen, and a tap logs one. A forgotten day stays a gap rather than counting as a dry one, and a drink after midnight counts towards the evening it belonged to.
Free
No subscription, no purchases and no adverts. Nothing is held back for a paid tier.
Private
There is no account and no server. Your log is stored on your phone and is never sent anywhere, and the source code is public, so anyone can check.
Offline
Everything works without a connection, including the drink catalogue and its prices.
What it does
- Counts UK units, with prices and calories, from a catalogue of around nine hundred drinks at their label strengths, from cask ale to Polish vodka.
- Sets a gradual reduction plan within the limits in UK clinical guidance, and shows the budget it gives you each day.
- Charts each week and month against the ones before, with your streaks and what it all cost.
- Shows your heart rate, HRV and sleep from Apple Health against what you drank the evening before, if you allow it to.
- Logs from the Lock Screen and Home Screen widgets, and from Shortcuts.
- Exports your whole log whenever you want it: as a backup, or as a readable summary to share or to ask an assistant about.
A note on safety
GrogLog does not provide medical advice. It is intended to help you follow a plan agreed with your GP or an alcohol service. If you are dependent on alcohol, stopping suddenly can be dangerous: please speak to a doctor before you begin.
In England, the NHS lists alcohol support services near you, and Drinkline is free and confidential on 0300 123 1110. Alcoholics Anonymous is on 0800 9177 650, and Samaritans are there at any hour on 116 123.
Call 999 if you have a fit or seizure, see or hear things that are not there, or become confused while cutting down. These are signs that withdrawal has become serious.
