Acalma: Calma na Ansiedade

Acalma is a Brazilian app designed for moments when anxiety strikes. No registration, no subscription, no ads during breathing exercises. Everything works offline, and your records never leave your device.

MADE FOR MOMENTS OF CRISIS

When anxiety hits, you don't have time to search through menus. Acalma has a visible SOS button on the home screen: one tap immediately starts the 4-7-8 breathing technique, with an animated orb and calming instructions in Portuguese. After three cycles, we ask how you are doing. No ads, no distractions.

6 GUIDED BREATHING TECHNIQUES

• 4-7-8 Breathing — a powerful calming technique based on yogic pranayama. Ideal for panic attacks and insomnia.

• Box Breathing (4-4-4-4) — used by military personnel and professionals under high pressure.

• Coherent Breathing (5-5) — balances the autonomic nervous system.

• 5-5-5-5 Breathing — focus and stability.

• Diaphragmatic Breathing (Belly Breathing 4-6) — activates the vagus nerve.

• Long Exhalation (Releasing 4-8) — releases accumulated tension.

Each technique has an animated orb that expands on inhalation and contracts on exhalation, subtle tactile vibration on your smartphone with each phase change, and coaching copy in Portuguese (Brazil) explaining what is happening in your body.

4 SENSORY ANCHORING TECHNIQUES

• 5-4-3-2-1 Technique — a classic from CBT: 5 things you see, 4 you hear, 3 you touch, 2 you smell, 1 you feel. Brings you back to the present.

• Guided Body Scan — 5-minute body scan, from head to toe.

• Anchoring in the Present — 1 minute of focused presence.

• Mental Ice Cube — sensory imagery for acute crises.

PRIVATE ANXIETY DIARY

Record each episode: intensity from 1 to 10, trigger (meeting, traffic, before bed…), technique you used, and an optional note. The app reflects back your patterns: how many episodes this week, which technique helps most, intensity graph of the last 7 days.

Everything is stored in a local database on your device. We don't use the cloud, we don't require an account, we don't share with third parties. Compliant with the LGPD (Brazilian General Data Protection Law).

BRAZILIAN SOUNDSCAPES

Use during breathing exercises or just as background noise:

• Tropical Rain — warm, light, continuous storm.

• Cerrado Forest — birds and dry foliage.

• Serra Waterfall, Northeastern Beach, Late Afternoon Fan, White Silence — unlockable by watching a short video.

Sounds recorded with Brazil in mind: no generic ambient orchestra.

OPTIONAL DAILY REMINDER

Consistency is what makes the techniques work in times of crisis. Set a time (e.g., 8 PM) and Acalma will remind you to practice for 1 minute a day. No intrusive notifications. You can turn it off at any time.

QUICK TECHNIQUE

On the home screen, a shortcut takes you directly to the last technique you used. Build your routine without having to navigate.

100% FREE

No monthly subscription. No Pro version. No paywall on essential features. The ads that support the app appear in discreet corners of the journal and the technique list, NEVER during a breathing exercise, during an anchoring exercise, or during the SOS.

WHO IS ACALMA FOR?

For Brazilians who experience daily anxiety and want practical, evidence-based tools (CBT, respiratory neuroscience), in Brazilian Portuguese, without handing over intimate data to foreign apps that charge high prices for basic functionalities.

IT IS NOT THERAPY

Acalma is a self-care tool; it does not replace professional help. If anxiety prevents you from living, seek a psychologist or a free CAPS (Psychosocial Care Center) from the SUS (Brazilian Public Health System). In case of a severe crisis, call CVV: 188 (24/7, confidential, free).
