## What is iKima?

When your mind is racing, you do not need another thing to manage.
Follow a gentle visual pace on iPhone or haptic guidance on Apple Watch.
iKima gives you a simple place to pause, breathe, and notice how your body responds — on iPhone or Apple Watch.

Start with Belly Breathing, free.
Choose one minute when that is all you have, or stay longer when you need it.

FIND A BREATHING RHYTHM THAT FITS

Premium unlocks four more guided techniques on both devices:
• Physiological Sigh
• Box Breathing
• 4-7-8 Breathing
• Resonance Breathing  

Each technique has a short introduction and its own pace, so you can choose what feels right rather than forcing yourself into one routine.

NOTICE WHAT CHANGES — WITHOUT CHASING A SCORE
After an iPhone session, you can optionally take a 20-second fingertip camera pulse estimate before and after practice. Retry it, skip it, or simply breathe — a reading never blocks or interrupts your session.
Apple Watch can guide your practice with haptics and read heart rate through HealthKit while you breathe.

Your Dashboard keeps the result understandable:
• See how heart rate or pulse changed in your latest session
• Clearly see whether a reading came from iPhone camera or Apple Watch
• Review practice history, weekly progress, and a 21-day rhythm
• See plain-language insights from your own practice patterns
• With Premium and Apple Watch data, see today’s HRV and resting heart rate in the context of your personal 30-day range  

iKima never averages iPhone-camera and Apple Watch readings together. Missing data is explained, never invented.

UNDERSTAND YOUR APPLE WATCH DATA
When Health data is available, iKima can show heart-rate trends and HRV as SDNN — the HRV measure Apple Watch records in Health. Newer Apple Watch models may also show a separate recovery-focused HRV, so the numbers can differ.

PRIVATE BY DESIGN
No account. No data sold.
• HealthKit access is read-only
• Camera frames are processed live and never saved
• Health measurements and session history stay on your devices
• Choose whether to share usage analytics during setup, and change your choice anytime in Settings → Your Data
• Analytics never include BPM, HRV values, raw camera signals, or images
• Export or delete your data directly from your iPhone


BUILT ON PUBLISHED RESEARCH
The breathing rhythms and camera-reading approach are explained with citations at sentiralabs.app/learn, including research on structured breathing, slow breathing, and fingertip camera pulse measurement.
iKima is a wellness and breathing-practice app, not a medical device. Readings and insights are for personal observation only; they do not diagnose stress or any health condition.
Start with one minute of Belly Breathing — free, with no sign-up.

### 5/5 — Ikima is for me!

*2026-09-24*

Simplicity is the best thing about this app - it helps you focus regularly on breathing exercises during the day & has measurable outcomes/simple reports.

Would also be great if there was a way for me to enter the most stressful times of my day. Ex: Weekday mornings between say 8-11am or evenings between 9-10pm. Also could suppress these schedules on Friday or public holidays?

**Developer response:** Thank you for the comments.
I’ve noted your feedback for future planning.

### 5/5 — Focuses on On Thing Only🥇

*2026-09-15*

- Takes your pulse
- Runs you through a simple breathing procedure
- Takes your pulse after

Provides reports on your relaxation over time

Love this App

**Developer response:** Thank you — you've described exactly what iKima is for: a reading before, one after, and a record of how your body settles over time. If you have an Apple Watch, the same session runs on your wrist with haptic pacing and live heart rate. Happy breathing!

## Version history (last 5 releases)

### V1.2.2 — 2026-10-23

More clarity, more control.

• A redesigned Dashboard separates Today and Trends. See how your latest practice changed your heart rate or pulse, and tap Your Insights for a clearer view of your patterns.
• Premium Apple Watch users can now see today’s HRV and resting heart rate in their personal 30-day range. Camera-based relaxation trends can now include RMSSD changes.
• More control over your data: choose whether to share usage analytics, turn sharing off anytime, export your data, or delete it from this iPhone. Usage analytics are stored in the EU.
• Apple Watch gets a unified teal breathing ring, clearer results, an easier Stop control, and improved Reduce Motion support.
• Better readability across the app, plus refinements to reminders, weekly goals, subscriptions, localized technique names, and Premium restoration.

### V1.2.1 — 2026-09-29

Box Breathing now runs an even 4-4-4-4 — four seconds in, hold, out, hold — for seven whole cycles. The camera reading screen shows the rear-camera layouts, so you can see where to rest your fingertip. After a few sessions, free users get one full run of Physiological Sigh to feel what a Premium technique is like; iKima tells you on the Dashboard when it is ready. Belly Breathing remains free. And you can now set a daily practice reminder on iPhone as well as Apple Watch, in Settings.

### 1.2 — 2026-09-14

Practice all five breathing techniques on iPhone or Apple Watch, each with a short guide on how it feels and why it works. Optional 20-second camera readings compare your response before and after a phone session. The refreshed Dashboard adds Your Insights — plain sentences drawn from your own sessions, such as when you practise most and what to try today — and a relaxation trend that now works from Apple Watch heart rate or the iPhone camera, each source shown on its own. Belly Breathing remains free; Premium includes Your Insights, your relaxation trend, four more techniques and personalised suggestions on both devices. The whole app also has a calmer new look: a softer mist-teal background and clearer cards, with text that now follows your iPhone's text-size setting everywhere.

### 1.1 — 2026-08-11

Steadier readings and a smoother start. Heart rate and HRV now stay in sync after you grant or revoke Health access, your dashboard refreshes the moment you return to it, and the welcome screen fits smaller iPhones properly.

### 1.0 — 2026-07-29

No release notes.
