iOS Beta · Limited spots

Get early access to Heliobios.

We're invite-only while we finish polishing the first release. Drop your email and we'll review every signup personally — when we're ready to bring you on, we'll send a personal invitation with everything you need. No card, no commitment — just a chance to be among the first + help shape what ships.

What wearable do you use?

One email per device. Position is locked when you sign up — sharing the page with friends doesn't bump you back.

How it works

  1. 1
    You join the waitlist

    Email + name + which wearable you use — that's it. Takes 20 seconds.

  2. 2
    We review your signup personally

    Every signup gets read by a human. We invite the next round based on cohort balance (wearable type, geographic distribution) and current capacity — not just signup order.

  3. 3
    You receive a personal invitation

    If you're a good fit for the current round, we send you a direct email with everything you need to install the app and connect Apple Health or Oura.

  4. 4
    Public launch when you're happy

    Beta runs until the experience is solid. Your data carries over — no reset, no re-onboarding.

Common questions

What does "beta" mean here?

Heliobios is a working app that's ready for real users — beta just means we're capping signup so we can respond fast to feedback and bugs without ten thousand new users hitting the support inbox at once. The science engine + UI are production-grade.

Do I need an Apple Watch or Oura ring?

Not strictly — but the personal sensitivity analysis works best when you have at least one wearable feeding sleep + heart-rate data. The space-weather + forecasting features work without one.

What does it cost?

Free during beta. After public launch, Premium is $12.99/month or $99/year with a 14-day free trial. The space-weather forecast and a basic version of the daily score stay free forever.

What about my data?

Your raw biometrics never leave your phone — they're processed on-device into scores and z-scores before anything syncs. The full architecture is in our privacy policy.

I signed up but lost the position email — can I check again?

Drop the same email into the form again. You'll see your current position and we won't double-add you to the list.
