Quit any addiction, with an otter by your side.

What is Loutra?

Loutra is an addiction and sobriety tracking app for iPhone and Android. 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 on the App Store and Google Play, with an optional subscription. Loutra does not replace a healthcare professional.

Your landscape

Your clean days grow a little world

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 21 free mini-games or record an urge in your journal. These tracking tools are not a treatment.

Protection · iPhone

Block what pulls you back

Turn on Apple’s own filter for adult websites in one tap. It works in Safari, in other browsers and in web pages opened inside apps.

Give each app its own time per day. When it runs out, the app stays locked until midnight, with five more minutes once a day if you really need them.

You set it while you’re calm, and Loutra holds it for 72 hours: no switching it off and no extra time in a weak moment. Adding apps stays possible at any time.

Premium, on iPhone with iOS 16 or later. It runs on Apple’s Screen Time: Loutra never learns which apps you pick.

Widgets

Your otter on your home screen

Seven widgets for iPhone and Android: your otter with its name, your counter, your next milestone, money saved, time recovered, your week of check-ins and a new phrase every day. The otter widget is free; the other six come with premium.

Gone fishing

A pond full of real fish

Cast a line 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.

SmokingVapingAlcoholCannabisScrollingAdult contentGamblingSugarVideo gamesSocial mediaCaffeineNail biting…and anything else you name yourself

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.

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 ads in the app, and nothing sold. We measure our own ads with Meta and Apple Ads (installs, app opens, subscriptions), never with what you track. On iPhone, your advertising ID is shared only if you allow it.

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.
