A quit clock
Days and hours since your last can, your longest run, and the total number of days you have been canless. The home-screen widget shows it without opening the app.

Canless
Quit energy drinks, one day at a time.
Canless counts the days since your last energy drink, and what those days gave back: the cans you did not open, the caffeine and the sugar you did not drink, and the money that stayed in your pocket. It is a quiet daily check-in, not a lecture. Canless is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. If you have questions about caffeine and your health, talk to a healthcare professional.

One check-in a day
Answer “still canless today?” and your streak grows. Miss a day and a shield covers it, so one bad evening is not the end of a hundred good ones.
A slip is data, not a punishment
Tap “I had one” and the clock starts again from now — your badges, your cravings, your totals and your longest run all stay, and the day still counts as a day you showed up.
The numbers that make it real
Cans not had, caffeine in milligrams, sugar in grams and sugar cubes, and money in your own currency at your own price per can. Every figure says what it assumes.
A sourced timeline
What commonly happens twelve hours, two days, a week, a month and a year after the last can — every entry with the study or the guideline it comes from, one tap away.
A craving button
A minute of breathing, a sourced fact, and two honest answers at the end: it passed, or it did not. Both are worth logging.
A taper, if cold turkey is not for you
Tell Canless how many you drink and when you want to be at zero, and it plans the way down — a daily allowance that walks to zero. Free, like every counter.
Yours, on your phone
No account, no sign-up, no server. Your whole progress is one file on your device; you can export it as a backup and import it on a new phone, free.

Why it exists
Most people who quit energy drinks do it alone, with nothing marking the days but willpower. Canless gives the attempt a shape: a clock that only moves forward while you do, numbers that translate the streak into money and caffeine and sugar, and a button for the moment a craving hits. The content is education, never a lecture — every health claim in the app cites a primary source you can open from the screen it appears on, from EFSA and WHO to the peer-reviewed withdrawal literature.
Free, with an optional Premium
Every counter is free, forever — the days, the money, the caffeine, the sugar, the streak, the timeline, the craving button, the taper and the manual backup. The free version shows a small banner ad served by Google AdMob. Premium — monthly, yearly, or a one-off lifetime purchase — adds:
- No ads
- The banner goes. Nothing about the counters changes.
- Craving insights and your full history
- Your cravings by hour and by trigger, your beat ratio, and the whole log instead of the last seven days.
- A savings goal
- Name what you are saving for and Canless shows the day you reach it at your pace.
- Notes on your craving log
- A line on any craving — what was happening, what worked.
- Extra reminder nudges
- The evening reminder, at up to three more moments you pick.
- Automatic backup
- Your save file rewritten to a document you choose, every time you leave the app — it survives even an uninstall.

Frequently asked questions
Is Canless free?
Yes. Every counter is free, forever — the days, the money, the caffeine, the sugar, the streak, the timeline, the craving button, the taper and the widget. The free version shows a small banner ad. An optional Premium (monthly, yearly, or a one-off lifetime purchase) removes the ads and adds craving insights, a savings goal, notes, extra reminder nudges and automatic backup.
Do I need an account?
No. There is no sign-up, no login, and no server. The app does not know who you are.
Where is my data?
On your phone. Your whole progress is one file in the app's own storage. You can export it as a backup file and import it on a new phone — that is free. Premium can also rewrite a backup automatically to a document you choose.
Is Canless medical advice?
No. Canless is education and habit tracking, not medical advice. It is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Every health claim in the app cites a primary source you can open from the screen it appears on — EFSA, WHO, StatPearls and the peer-reviewed sleep and withdrawal literature. If you have questions about caffeine and your health, talk to a healthcare professional.
What happens if I slip?
You tap “I had one” and the clock starts again from now. Your badges, your logged cravings, your lifetime totals and your longest run all stay — a slip gives no can back, so the app does not take anything back either. The day still counts as a day you showed up.
What platforms is it on?
Canless is an Android app, coming soon to Google Play. Other platforms may follow later.
