What do I need to use Erkan?
A wearable that records sleep and heart rate. Today the web app shows every screen on demo data and takes manual logs. Device sync is not open yet: Apple Health and Health Connect are in testing, and Fitbit and Pixel Watch come next.
Why compare me with myself instead of with other people?
A resting heart rate of 58 can be great for one person and a warning sign for another. Your own recent history is the most useful reference for whether today is normal for you.
How long until my scores appear?
Scores need 7 days of data to build a first baseline and settle after 14. Until then Erkan shows your raw numbers and says the baseline is still forming.
Is Erkan a medical device?
No. Erkan helps you understand trends in your own data. It does not diagnose or treat anything. Talk to a doctor about symptoms or lab results that worry you.
What does Intelligence see?
The last 14 days of your scores and baselines, a nutrition summary, flagged lab values and today's journal. It never receives your name, email or notes.
Is there an iPhone app?
Not yet. The Erkan iPhone app, with an Apple Watch glance, is in internal testing and not on the App Store or TestFlight. The web app is open now.
What does Premium cost?
₹299 a month or ₹1,999 a year, with a 7-day trial once per account. During the beta, signed-in accounts get Premium free.
Can I take my data with me or delete it?
Yes. Settings has a JSON export of every table and a delete button that removes your account and all of its rows.
Why are my scores blank on day one?
Erkan needs a week of your data to know what normal looks like for you. Showing a score before that would mean comparing you with a made-up average.
Can I mix data from two watches?
Each source is merged by one rule, and HRV from different device families is never mixed in one baseline, because the devices measure it differently.
Which time zone decides my day?
Yours. A night belongs to the date you wake up, in your own time zone, not the server's.
Does Erkan work offline?
The web app shows a simple offline page and the iPhone app keeps your last scores on screen with an offline banner. New scores need a connection.
Who makes Erkan?
Seigotic, a small company in India. Erkan is built and run by the same team.
See your own normal.
Open the web app to explore every screen on clearly labelled demo data. Sign in with Google to log meals, habits and labs; your own scores arrive when device sync opens.
The iPhone and Apple Watch apps are in testing and not yet on the App Store.
