Up to 15 days for tri versus the advertised up to 7 days for Fitbit Air. Actual battery life depends on usage.

AI without a geographic puzzle

tri’s assistant is included in our membership in Russia. Google Health Coach has a separate eligible-country list and requires Premium.

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.

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.

Competitor advantages to consider

Fitbit Air is lighter and starts at $99.99 for the hardware. Coach membership is charged separately after a trial. Google supports personalized workout plans and a broad range of workflows. Choose tri for Russian availability, Russian service, bracelet commands and battery life. Requiring a Google Account does not by itself make Fitbit unusable in Russia.

Questions about choosing.

How is tri better suited to Russia than Fitbit?

Reasons to choose TRI: a custom habit journal with metric comparisons and chat analysis, alarm commands, and up to 15 days per charge versus up to 7 for Fitbit Air. Google also offers photo-based food logging and memory. Another practical TRI advantage in Russia: its assistant is included in a locally available membership; Russia is not listed among Google Health Coach’s supported countries.

Does Fitbit lack useful AI?

Google has AI for metrics, memory, food and documents. For a buyer in Russia, service eligibility is the key question. tri includes these workflows in its membership and Russian app.

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?
