A PLACE WITHOUT PRETENSE
For days when there is too much.
Even for the very ordinary ones.
You don't have to be able to name every feeling. Choose what feels right for you right now — a minute of breathing, a few words in your journal, or a moment of silence.
Put aside what you are carrying in your head.
Free writing, a gentle question, or a short note about a bodily sensation. Your journal doesn't need to have a correct answer.
Look into the diaryYou did enough today.
Short bedtime stories, rain, breeze, and sound layers with a timer. Create your own moment before sleep.
Enter nightly restYour moment. Your pace.
What do you need right now?
Choose what you need now. Even two minutes count.

My eveningAttention map
Choose an obstacle and try a small next step. The map does not determine your spiritual attainment.
Return without struggle
Noticing distraction is part of practice, not failure.
Bring attention back gently, without judging yourself.
Recognize clarity
Calm and sleepiness are not the same as alert clarity.
You reported sleepiness. Rest or choose a better time; this is not failure.
Balance effort
Find a comfortable balance of intention and relaxation.
You reported forced effort. Try a break or a shorter familiar practice.
ONE APP. YOUR OWN PACE.
Small moments.
Throughout the day.
01 — GENTLE START
Try at your own pace You first. Then the rest of the day.
Morning wake-up offers you 60 seconds for water, breath, and noticing your body. No rushing. With space to name how you feel.
- Short morning ritual
- Custom mood log
- A small intention for today

MORNINGS AND EVENINGS AT YOUR BEDSIDE
A little nature. Room to exhale.
The bedside view brings together a peaceful landscape, a clock and optional weather for a selected city. Daily rhythm switches the theme at your chosen times. The landscape is illustrative, not a live weather image.

Not every day has to be better.
Some days just need to be lived more gently.
No broken streaks. No comparisons.
You return when you need to.
EVIDENCE, WITHOUT MIRACLE CLAIMS
What research supports. What we do not yet know.
Support for everyday habits. Mindcool’s effects have not yet been clinically validated.
Insomnia: professional treatment comes first
CBT-I is the recommended first treatment for chronic insomnia in adults. Mindcool does not provide this therapy programme.
AASM · 2021 ↗Music: a possible complement
A Cochrane review supports improved subjective sleep quality with music. Mindcool’s particular sounds have not been studied.
Cochrane · 2022 ↗A frequency is not a treatment
We do not label 432 or 528 Hz tones as healing. Binaural-beat research is inconsistent and does not validate our app.
PLOS ONE · 2023 ↗Reviewed on 7 October 2026. This is not an exhaustive list of studies or clinical validation of Mindcool.
For parents
A child’s safety starts with a person.
The free Children and safety section helps find human support for stress, bullying and cyberbullying. It does not collect incident accounts or replace adult supervision or professional care.
Children and safetyA shared routine
Plan a calm evening together: washing, a story in your own voice, a hug and goodnight. Consistency and closeness matter more than another screen.
Sleep · 2009 ↗The last hour without screens
The AAP recommends putting screens away at least an hour before bed. We therefore do not offer the bedside view as a glowing sleep aid for a child’s bedroom.
AAP ↗Call a parent after a bad dream
The app does not monitor a child’s safety or prevent nightmares. A frightened child needs an adult nearby; recurring distress also deserves a conversation with a paediatrician.
HealthyChildren / AAP ↗Support in difficult moments
You do not have to force yourself to feel better.
With depression, even a small step can feel difficult. You can write down what you need or reach out to someone close. Encouragement in an app does not replace treatment or professional support.
NICE NG222 ↗Panic, breathing and tetany
If focusing on your breath feels uncomfortable, stop and notice things around you. Do not force deep breaths or breath holds. The app cannot diagnose tingling, cramps or chest pain; these may need medical assessment.

Your feelings
are not scores.
Mindcool is being created as a calm space for daily self-care. That is also why we speak openly about what is already working and what we are still preparing.
How we work with data todayNo account, no mandatory sharing.
Open the web app without an account. The optional encrypted vault keeps entries in your browser; temporary mode loses them on closing. The older Android APK has different capabilities.
You know what is actually available.
You can try Breath, Journal, and local sounds right now. AI chat, synchronization, and system widgets are still in development.
Support has its limits.
Mindcool does not replace professional help or crisis services. You will find a separate section with help contacts in the app.
START WITH ONE SMALL MOMENT
Your space.
Always a little bit closer.
The current web app is free, with no registration or payment card required. Open it on a computer, tablet or phone. The older Android APK and planned iOS release have different availability.

YOU MIGHT BE INTERESTED IN
A few answers.
No unnecessary words.
Who is Mindcool for?
For people who want to find a moment for breath, journaling, or a calm ritual during the day. You don't need meditation experience or a strict plan.
Is the app free?
The current web app is free, with no registration or payment card required. Open it on a computer, tablet or phone. The older Android APK and planned iOS release have different availability.
Does it work without the internet?
After downloading the optional offline pack, you can use bundled content without internet. Weather needs a connection. Enable the encrypted vault and make backups to keep your notes; temporary mode does not retain them.
Can I choose a light appearance?
Yes. In Profile, select Warm light or Silent night. You can also switch this website using the sun or moon button in the top bar.
Are AI and watch integration working yet?
Not yet. The interfaces are ready, but live AI chat, health data, watch apps, and system widgets are not yet connected. Their screens are marked as previews.
Does Mindcool replace a psychologist or therapy?
No. Mindcool is a tool for daily self-care. It does not provide diagnosis or treatment and is not intended for handling acute crises.
