Why not reset your mind and body by regulating your breathing?

CalmiRhythm is an app that uses sound to guide you through classic breathing techniques such as 478 breathing and box breathing.
You can also create your own original breathing techniques (you can freely set the order [inhale, hold, exhale] and duration. *10 seconds for each).

[Key Features]
- Preset breathing techniques (1:2 breathing, 3-2-3 breathing, 4-7-8 breathing, box breathing, alternate nostril breathing)
- Create your own original breathing techniques (you can freely design the order, duration, number of sets, etc.)
- Voice guide (includes inhale/hold/exhale announcements)
- Gentle guidance with the voices of Zundamon and Shikoku Metan
- Visual animations synchronized with the rhythm
- Customizable background music playback
- Save breathing history and automatically record "Recently Used Breathing Techniques"

[Recommended for the following situations]
Relaxing before bed (478 breaths)
Before concentrating on a task (box breathing)
When feeling stressed or anxious
Supporting yoga or meditation breathing
Those who want to make a breathing technique a habit but can't stick to it
Those who want to create and practice their own original breathing rhythm
When you want to try a new breathing technique that you've seen online, on TV, or in a yoga class!

[Reason for creating this app]
I couldn't find many commercially available apps that accurately guide you through your breathing with audio,
and there were even none that supported less common breathing techniques or your own rhythm, so I developed this one myself.
I especially hope that many people will experience the feature that allows you to freely create your own original breathing techniques!

It is solely a tool intended to support general health, relaxation, and concentration.

Also, when practicing breathing techniques, more repetitions is not necessarily better.
Please use at a pace that is comfortable for you.
