A coach you can talk to.
Ask why, push back, or say “not today.” Nikky checks in, answers what you actually asked, and adjusts the pace. Nothing is scripted, and nothing is silently planned for you.
AI health coaching
The health coach that actually talks back.
Most plans are written once and never listen. Nikky checks in, answers your questions, and adjusts the pace to your week. No rigid scripts, no guilt trips. Because it reads your Apple Health data, its advice reflects how you slept and moved, not guesses.
Plans from $1.99/month · $19.99/year · or $99.99 once. Built for iOS 15 and up. See pricing ↓

I slept badly and only have 10 minutes today.

Let’s keep today small. Try a short, easy walk if you feel up to it, then check in about your energy.

A few things people ask before they join
objections
How is Nikky different from a workout library with a chatbot?
Most apps hand you a plan and stay silent. Nikky is the conversation. It checks in, answers your questions, and changes the plan around your real sleep, energy, and recovery.
What does Nikky do with my Apple Health data?
With your permission, Nikky reads sleep, movement, and recovery signals from Apple Health. Profile details, recent health readings, and chat history are saved on your device; when you enable wearable coaching with an online AI provider, relevant summaries and conversation context may be sent to that provider, and online backup can store saved conversations separately. Revoke Health access in iOS to stop future reads, use available app controls to clear chat history, and contact privacy@nikkyhealth.com about deleting other saved data or backups; revoking access alone does not erase saved records.
Storage and retention detailsWill Nikky nag me if I fall off?
No. Nikky doesn’t count streaks or guilt-trip you. If your week falls apart, it makes the next step smaller, not louder.
What does it cost?
Nikky Companion is $1.99/month, $19.99/year, or $99.99 for lifetime access. No contact forms and no hidden tiers.
Why this price?
Running an AI coach has real costs, including AI model usage, servers, and Apple’s App Store fee. We use model aggregators and prompt caching to keep it as low as we can, and $1.99 is what covers it honestly.
Will there be other versions?
Yes. We’re building editions for newer iOS versions with additional capabilities, and we’ll announce them when they’re ready.
Who is Nikky for?
Nikky is for people who are done with tracking apps that look helpful but never really adapt. If you want a coach that changes with your week, this is for you. It is for everyday wellness support, not medical diagnosis, treatment, or emergency help.
Built by people who have been in the loop
founders
Gus Sun, PhD & Nasim Bahadorani, DrPH, LHC
We built Nikky because most people do not need more tracking. They need a coach that reacts to their real life — the missed sleep, the busy week, the low-energy day, and the one habit that actually sticks. We built a coach that listens first, never judges, and never makes you feel behind.
