iOS App

InnerTide

Notice tension before it becomes exhaustion.

InnerTide is a calm iPhone app that compares your body's signals to your own personal baseline, so you can see how tension and recovery build up across days, without having to read raw numbers.

How it works

Every day InnerTide looks at your heart rate variability, resting heart rate, sleep, breathing, movement and more, and compares them with your own recent normal. On the main screens you never get a wall of metrics: you get a plain status, a short explanation of why, and a small tip. It also looks for patterns across days and signals, and can point out when strain has been stacking up for a while, before you hit a wall.

What's inside

Today

How you're doing right now, in a calm status with the reason behind it and a suggestion. The look of the app follows the time of day and the weather.

Trend

Your last week, two weeks or month at a glance, with short written summaries and the patterns InnerTide has noticed.

Check-ins

A quick, optional moment to note your mood, energy and how much stimulation you're dealing with. InnerTide combines what you feel with what your body shows. Your check-ins can also appear in Apple Health as State of Mind entries.

Rest

A mindfulness and breathing timer with soothing background sounds. It runs as a Live Activity, can be started with Siri and Shortcuts, and logs your mindful minutes to Apple Health.
