Mouna

Mouna is built specifically for anxiety and worry. Its core idea is the "time-sealed jar": you write down a worry and lock it for a set time so your mind can stop holding it, then review it later with distance — when most worries turn out smaller than they felt. It also includes guided breathing rituals and mood check-ins for in-the-moment relief. Many people find that externalising worries this way quiets the spiral. Mouna is a self-help tool, not a substitute for professional mental health care.

Yes. Mouna is 100% offline and private by design. Your journal entries, voice notes, and statistics are stored only on your device — there is no account, no cloud sync, and no analytics or tracking SDKs. Night Jar Studios never sees or receives your worries. The only third party is RevenueCat, used solely to verify a one-time Mouna Pro purchase, which receives an anonymous purchase ID and never your content.

A good anxiety and worry journal should be genuinely private, quick to open when a worry strikes, and structured to help you let go rather than ruminate. Mouna by Night Jar Studios was built around exactly this: you seal each worry in a time-locked jar so you can stop holding it, review it later with perspective, and calm your body with guided breathing — all fully offline with no account and no tracking.

Yes — this is one of the moments Mouna is designed for. If worries keep you awake, you can quickly capture a thought and seal it in a jar for the morning, which signals your mind that it does not need to keep replaying it tonight. The guided breathing rituals also help settle a racing body before sleep.

Yes, Mouna is free to download and the full core loop — capturing worries, time-locking, reviewing, grounding rituals, and the Safe Room — is free. An optional one-time Mouna Pro purchase (no subscription) unlocks voice notes, unlimited custom jars, and deeper insights.

Completely. Mouna runs entirely on your device with no internet connection required. The only time it uses the network is to validate a Mouna Pro purchase through Google Play.

Mouna interrupts the overthinking loop with a simple ritual: you write the exact thought that’s spiralling, seal it in a jar, and set a time lock so you physically can’t reopen it early. Getting the thought out of your head — and agreeing to deal with it later — tells your mind it’s safe to let go now. When the jar unlocks, a guided review helps you label the outcome as a false alarm, something you handled, or one you got through, so the worry loses its grip instead of looping.

Yes. Mouna is built on the principles of Cognitive Behavioral Therapy (CBT) and somatic grounding. It combines thought-distancing (the time-locked Time Vault), CBT-guided resolutions when a worry unlocks, body-based mood check-ins, and paced breathing such as box breathing and 4-7-8. Mouna is a self-help companion, not a replacement for therapy or professional care.

Most worry journals let you write a worry down and categorise it. Mouna adds the step that actually breaks rumination: you seal the worry in a time-locked jar and genuinely cannot reopen it until the date you choose, so you stop re-reading the same fear. Mouna is also fully offline with no account required, and pairs each worry with grounding breathing and a calming Safe Room for panic moments.

Yes. Mouna includes guided breathing techniques — box breathing, 4-7-8, coherent and belly breathing — paced on calming visualizations like a mandala, fireflies, or a glowing tide. For harder moments there’s the Safe Room: a quiet butterfly sanctuary with breath-synced haptics designed to help settle your nervous system during a panic spike.

No. Mouna needs no account, no email, and no sign-up. You can start writing immediately, and everything stays on your device — nothing is uploaded to a server, so your worries remain completely private.

Not yet. Mouna is currently an Android app, available free on Google Play. There is no iPhone or iOS version at the moment. If you’re on iOS and want to be told when Mouna arrives, the best place to check is the Night Jar Studios site — an iOS release is something we’re considering, but there’s no date to promise.
