YOSS is a browser and Telegram self-tracking app that turns logged sleep, water, activity, and wellbeing into a daily Score and suggested next step. Its value depends on consistent entries, and it is not a medical tool.

Our verdict on Yoss

6.5/10

YOSS may suit people who want a structured diary for sleep, hydration, activity, and everyday wellbeing without creating an account first. Its clearest strength is the combination of a daily Score, component balances, trends, and practical logging tools, with optional Telegram sync and export. The main caveat is that the output depends on self-reported entries and is not medical guidance. YOSS also does not publish fees or detailed security and data-retention practices, so users should weigh those gaps before syncing personal information.

What is Yoss?

YOSS is a personal self-tracking app available in a browser and as a Telegram Mini App. Users can log sleep, drinks, food, activity, steps, stress, and body states, then view a daily Score and a summary of contributing factors.

The app also offers trend views, reminders, a Life Book for significant moments, and data export. Local use does not require registration; Telegram sign-in enables cloud history and synchronization. Dedicated Apple and Android apps are listed as coming soon.

YOSS is intended for self-observation, not medical care. The site says its scores and suggestions depend on what users enter; it does not publish clinical validation, fees, or detailed security and data-retention practices.

How Yoss works

YOSS builds a daily view from entries users make about sleep, water, food, activity, steps, stress, and wellbeing. It turns those records into a Score from 0 to 100, four component balances—recovery, energy, water, and calm—and an indication of how much data is available. The app can explain factors behind the Score and suggest an action when it has enough information.

Key features

Daily Score

A daily rating from 0 to 100 is shown alongside recovery, energy, water, and calm balances. YOSS also indicates whether there is enough logged data for its assessment.

Personal diary

Users can record drinks, sleep, food, activity, steps, stress, and body states, then review or edit those entries.

Suggested next step

The app explains factors affecting the day and can suggest a next step when it considers the logged data sufficient.

Patterns and trends

YOSS presents changes and patterns as more history accumulates. Personalized conclusions and forecasts are described as developing over time.

Life Book

A separate space for significant moments supports revisiting entries and assembling a monthly overview.

Reminders

Users can set a Score range for alerts, quiet hours, and notification pauses. Background delivery depends on browser and device support.

Data portability

The app can be used locally, synchronized through Telegram, and backed up as JSON. It can also import compatible YOSS data or an Apple Health XML export.

Pros and cons

What we like

Can be started in a browser without registration.
Supports a broad set of manual entries, including sleep, hydration, steps, activity, and stress.
Shows the components behind its daily Score rather than presenting only a single number.
Offers local use, optional Telegram synchronization, JSON backups, and Apple Health XML import.
Includes trends, reminders, and a separate journal for significant life events.

Watch out for

The Score and suggestions depend on information users enter, so incomplete or inconsistent logging can make the picture less useful.
YOSS does not replace medical care, and the site does not describe clinical validation for its scores or recommendations.
Cloud history and synchronization require Telegram sign-in, which may not suit users who prefer not to connect an account.
Audit, encryption, and detailed data-retention practices are not published on the site.
Dedicated Apple and Android apps are not yet available.

Yoss fees

YOSS does not publish fees or describe a paid subscription on its site. Check the app for any charges or payment terms before using a feature that may involve payment.

Is Yoss safe?

YOSS says it is for self-observation and does not replace medical care. Its assessments and suggestions depend on user-entered information, and the site does not describe clinical validation. Treat the Score as a personal tracking aid, not a diagnosis or treatment recommendation.

Local entries are saved in the browser; cloud history and synchronization require Telegram sign-in. The site describes backups and synchronization but does not publish details about encryption, data retention, or an independent security audit. Consider what health-related information you are comfortable storing before using cloud features.
