After each successful 30-day streak, including those rest days, your Life Tier™ increases by 500 daily steps, up to 20,000.
Signum Chat tracks your progress, celebrates streaks, and keeps the focus on building a healthier, longer life over time.
You don’t have to open anything.
Just tell Signum Chat how you’re feeling.
Crisis Mode™ is designed to recognize danger and switch on by itself.
It will pause normal conversation, respond with care, and guide you to help like 988 in the United States or 911 if there’s immediate danger.
You don’t need perfect words—just say what’s going on.
No.
Signum Chat provides general information and support, not a substitute for professional medical care.
For personal medical decisions, talk to your clinician.
If you’re in crisis, use local emergency services or, in the United States, call or text 988.
Yes. You can cancel in your device’s subscription settings.
If you cancel, paid features continue until the end of the current billing period.
