Serene: Calm is a skill that grows from a few minutes a day. A quiet place for your mind.
I wanted meditations I could listen to on a plane, in the woods, anywhere: guided practices, visualisations and affirmations read aloud by a calm voice, with no internet needed.
Serene brings guided meditations, guided visualizations and affirmations into one calm app, for inner calm and harmony. Every session is read by a gentle voice recorded ahead of time and built into the app, so it all works offline. Free, with no ads, no premium and no account.

What’s inside
Ten guided meditations
Calm in 3 minutes, breath awareness, body scan, loving-kindness, letting go, inner harmony, gratitude, morning intention, self-compassion and a sleep wind-down.
Ten guided visualizations
A safe place, a forest walk, the ocean shore, a mountain lake, healing light, meeting your future self, releasing worries, an inner garden, a goal achieved and a starry sky.
A calm voice, offline
Every session is read by a natural neural voice, recorded ahead of time and shipped inside the app. You can switch to your phone’s own voice in Settings.
240 affirmations
Twelve themes, from calm, self-love and confidence to sleep, courage and good morning. An affirmation of the day, favourites, your own lines and a daily mix read aloud with room to repeat.
A vision board
Add what you want to bring into your life: a photo, how it looks and feels, and a line to say to yourself. Visualize my board turns it into your own guided session.
Your own voice
For your own affirmations and visions, record yourself in the app or upload an audio file. Or let the phone read your words.
Breathing
Calming 4-6, box, 4-7-8, coherent, the physiological sigh and equal breathing, with a glowing orb, soft tones and a light vibration.
Silent meditation
A timer from 3 to 60 minutes with any background sound and a bell at the interval you choose.
17 soundscapes
Real recordings of rain, thunderstorm, ocean, stream, wind, forest birds, a fireplace, a café, a train and more, reshuffled endlessly so they never audibly loop. Plus soft generative music, a warm tone and deep noise. The sound dips while the voice speaks.
Journal and balance
Mood check-ins, three good things, notes, a two-week mood chart, a practice calendar, your streak and minutes. The wheel of balance rates body, mind, relationships, work, rest and joy.
Gentle reminders and a widget
A morning affirmation and an evening wind-down at the time you pick, and a home-screen widget with the affirmation of the day.
Yours, in two languages
Back up to a JSON file (photos stay on the phone), light and dark themes, and English and Russian written natively, not machine-translated.
Six ways to breathe
| Pattern | Rhythm | Good for |

| Calming | 4 · 6 | Winding down |
| Box | 4 · 4 · 4 · 4 | A racing mind |
| 4-7-8 | 4 · 7 · 8 | Falling asleep |
| Coherent | 5.5 · 5.5 | Balance |
| Physiological sigh | 2.5 · 1 · 6 | The fastest release |
| Equal | 4 · 4 | Centring |
Good to know
Is there a premium version?
No. Every meditation, visualization, sound and affirmation is unlocked for everyone, with no ads, no trial and no subscription.
Is anything sent anywhere?
No. No accounts, no servers, no analytics, and the app has no internet permission. Your journal, favourites and visions live in a local database on the phone. Settings → Backup saves everything except photos to a file you keep.
Is it medical or psychological treatment?
No. Serene is for relaxation and well-being. It doesn’t replace a doctor or a therapist.
Whose voices and sounds are these?
The narration was made with open neural voices: Silero for Russian (CC BY-NC-SA 4.0) and Kokoro-82M for English (Apache 2.0). The nature recordings come from the Blanket project, under CC0, CC BY, CC BY-SA or public domain. Full credits are in the README.
