Hi, I’m Koko. Your companion for beating addiction.

A simple, private app that helps you break unhealthy habits — one gentle day at a time. Daily pledges, honest check-ins, and a calm koala who’s always in your corner.

Recovery isn’t a straight line. Some days are easy, some days are heavy. Koko simply stays beside you for every one of them — no shame, no pressure, just one step at a time, together.

A day with Koko

Small moments that add up.

01
Watch every second count.

Your streak ticks along in real time — days, hours, minutes, seconds. Each one is proof you’re doing this. Koko even words it your way: days sober, days clean, days bet-free.
02
Make today’s pledge.

One tap to commit to the day ahead — with a little celebration from Koko. Add the reason that matters to you, and it’s waiting right there on the hard days.
03
Check in, honestly.

How’s your mood? How strong is the craving? What’s stirring it up — stress, boredom, loneliness, tiredness? It takes under a minute, and it’s how you start to see your patterns.
04
Write it out.

A private journal for each habit you’re working on. Some thoughts just need somewhere soft to land — and Koko’s ready whenever you want to write.
05
Talk it through.

When a craving hits at 2am, you don’t have to face it alone. Open the chat and Koko is right there — warm, patient and never judging.

Chat with Koko

Someone to talk to, when it matters most.

A private, judgement-free chat you can open any time — during a craving, a rough moment, or a sleepless night. Koko listens first, and keeps it short and kind.

Talk through urges and emotions as they happen
Gentle suggestions, like slow breathing or grounding, only if you want them
Safety built in — if you ever sound like you’re in crisis, Koko points you to real help
No shame. No pressure. Just help.

Koko is a supportive companion, not a therapist or medical service.

Safe. Private. Judgement-free.

What you share with Koko stays yours.

Lives on your phone

Your check-ins, journal entries, pledges and streaks are stored on your device, not on our servers.

Chat, handled with care

To reply, Koko sends your chat messages to a secure AI service. They’re never sold and never used for ads.

No ads. No selling.

We don’t sell your data. This website uses Google Analytics to count visits, and the sign-up form uses Cloudflare Turnstile to keep spam out. You’re here to heal, not to be the product.

Why it works

Built on how change really happens.

Koko draws on ideas from cognitive behavioural therapy and behaviour-change research — the kind of small, repeatable habits that help real change stick.

NoticeRegular check-ins build awareness of your mood, cravings and triggers.
CommitA small daily pledge and a personal reason keep your “why” front of mind.
ReflectJournalling and insights turn tough days into things you can learn from.

Koko is a support tool, not a substitute for professional medical or mental-health care.

Good to know

Is Koko a replacement for therapy or treatment?

No. Koko is a day-to-day companion that can sit alongside professional help — it isn’t medical care, and it isn’t a crisis service. If you’re in danger, please contact your local emergency services.

Which habits can I track?

Alcohol, nicotine and vaping, drugs, gambling, porn, food, shopping and social media — one or several at the same time.

Where is my data stored?

Your check-ins, journal, pledges and streaks live on your device. Chat messages are sent securely to generate Koko’s replies, and we never sell them.
