tri bracelet with a textile strap — Bracelet and personal AI

Your habits, your insights

Create “An hour without notifications” or another habit of your own. Compare your metrics on days with and without it, then discuss the differences with AI.

Up to 15 days between charges

Easier to build a habit of wearing your device at night. Series 12 advertises up to 24 hours; Forerunner 570, 42 mm, up to 10 days.

Only the attention you choose

The bracelet has no screen. Open the app when you want to see your metrics or talk with the assistant.

Your journal and personal AI

Explore a habit
that is not in the catalog.

Create your own habit in TRI, log it in the journal or in conversation, and compare your metrics. The assistant explores your sleep, recovery and workout history alongside your entries, and you can ask follow-up questions.

How habit analysis works ↗

An hour without notificationsDemo data

01 · Your own habit

What matters to you.

Add what you want to explore to your journal. For example, an hour without notifications before bed.

No notifications todayLogged in the journal through chat

02 · Your metrics

With and without it.

Once you have enough history, compare days with and without the habit. This example shows sleep duration.

With the habit · 8 days: 7 h 32 min
Without the habit · 9 days: 7 h 04 min

Why the difference?

Does it help me sleep?

Sleep is 28 minutes longer on average. But you also had fewer late workouts on those days. We cannot yet separate their effect from the habit.

Next: compare days with similar strain.

An illustrative workflow, not a user testimonial. An association in your history does not prove causation. The assistant should flag insufficient data.

What does the assistant remember about me?

Your routine, goals, preferences and important circumstances. It consults bracelet history and your journal when they are relevant to the question. View, edit and delete its memory. Health information is saved with consent. Sync the bracelet for an up-to-date analysis.

tri assistantDemo data

Compare my recovery after late workouts with rest days.

After late workouts, sleep is 42 minutes shorter on average, overnight heart rate higher and HRV lower. Three evenings also included a late dinner. We cannot yet attribute this to training. Move your workout earlier, then we can compare the week with your baseline.

A next step to test the pattern

Here is a photo of my lab results. Why is one value highlighted?

The lab flags values outside its reference range. First, let’s check the test name, units and range on the report. A single out-of-range value does not explain the cause. Useful questions for your doctor include whether to repeat the test and which other results to consider alongside it.

Custom habits	Add your own habit, such as “An hour without notifications”. Log it in the journal or tell the assistant. Creating it in chat requires your confirmation.

Competitor advantages to consider

Watches offer a screen, GPS, apps and in-workout controls. Some models include ECG and other health features. One Apple Watch model cannot represent the whole market’s battery life; sports watches can last much longer. Choose tri for unobtrusive continuous tracking and personal AI in one app.

Scientific foundations

The methods are open.
You can look deeper.

Our articles explain research, inputs and calculation limits. We distinguish patterns in your history from proven causes.

Questions about choosing.

Why get tri if I already have a smartwatch?

Choose TRI for a custom habit journal, metric comparisons and personal AI in one app. Up to 15 days of battery help you wear it at night without daily charging. Apple Watch Series 12 specifies up to 24 hours of normal use, and Garmin Forerunner 570, 42 mm, up to 10 days. Watches are more convenient for maps, GPS and wrist apps.

Do watches have no AI at all?

Watches and their associated services have AI features. Siri, for example, executes commands and accesses some health data. Compare the specific workflow: history analysis, journal actions, nutrition, memory and language availability.

Can I track a habit that is not in the catalog?

Yes. In TRI, you can create a custom habit and log it in the journal or in conversation. Once you have logged days and bracelet data, compare days with and without the habit and discuss the differences with the assistant. It should not present insufficient data or a statistical association as a proven effect.

Is tri more accurate than its competitor?

This page compares features and workflows. Comparative accuracy requires separate device testing against reference measurements. Scientific articles explain our methods but do not themselves prove a sensor is superior.
