Loutra
Track your progress,
one day at a time.
What is Loutra?
Loutra is an addiction and sobriety tracking app for iPhone. It combines a counter for each goal, a daily journal, savings estimates and a virtual otter. You can start without an account. It is free to download with an optional subscription; Android is in preparation. Loutra does not replace a healthcare professional.
Your riverbank
Your riverbank grows with you
Every clean day plants something behind your otter. Reeds on day one, flowers in the first week, a young tree after a month, the den from day 60 and the big tree on day 90.
Nothing that has grown is ever taken back. A relapse pauses the tree for a day; it never shrinks it.
The shop
Dress her up
Name it, and it’s yours. Its mood follows how you’re doing — and it’s the first thing you see when you open the app. That’s the whole trick: you don’t come back for a chart, you come back for someone.
Every check-in earns shells. Spend them on hats and colours for your otter: shells are earned in the app, and never sold for money.

Breathing
When the urge hits, breathe
Open a breathing exercise and follow the rhythm on screen. You can also choose from 14 free mini-games or record an urge in your journal. These tracking tools are not a treatment.
Gone fishing
A pond full of real fish
Cast from her riverbank and fill your fishing log: 99 fish, nearly all of them real freshwater species that bite at their own hours of the day. Sell your catch for shells. It’s free, like every game in the app.
Every day
Everything else, one tap away
Add what you’re quitting
Pick from the list or type your own. Each one keeps its own count of clean days and its own record, so quitting two things at once doesn’t mean losing both when one slips.
One check-in a day
How was today, and how do you feel? Your otter celebrates with you, or comes over to comfort you. Its mood bar never drops because you had an honest bad day — which is exactly why answering honestly is safe.
See what you’re getting back
Enter what your habit costs in money or time. Loutra calculates estimates from your inputs and tracked days, then shows projections. These are personal estimates, not a promise of savings.
Talk to your otter
With premium, your otter answers when you write to it. It is not a therapist, and it says so.
Anything you name
Whatever it is you’re quitting
Smoking, vaping, alcohol, porn or social media: pick a goal from the list or name your own. Each goal has its own counter. Tracking a habit does not constitute an addiction diagnosis.

If you are dependent on alcohol or take benzodiazepines, seek medical advice before stopping: abrupt withdrawal can be dangerous. NHS sources: alcohol · benzodiazepines.
The day it goes wrong
Slip up? No shame here.
The counter for the affected goal restarts from the relapse date. Other goals and your history stay. Savings estimates subtract one day for a day with a relapse, without falling below zero. You can resume tracking without judgment.
You were honest and you came back. That’s the part that counts.
It’s okay. You’re still here.
Your streak starts fresh today.
No small print
Quietly on your side
Works without an account
You can track your goals without creating an account. An optional account enables backup and social features. AI chat sends your conversations to a remote service; exchanges are stored for 90 days. See the privacy policy for details. Privacy Policy.
No ads, nothing sold
Loutra makes money from an optional subscription, not from you. No advertising, and no cross-app tracking of any kind.
Not a doctor, and says so
Loutra is a companion, not treatment. It carries no medical claims, and it points you to real helplines when that’s what you need.

Quitting, explained honestly
Short pieces about the practical side of quitting. Every health statement carries the source it came from — the NHS, the HSE, or a peer-reviewed paper.
Does quitting with someone help?
"Shall we quit together?" The question hides two very different things: being supported, and stopping at the same time. Only one of them has a number behind it.
