Habitvs turns Apple Health data into a virtual companion named Kova. Sleep, recovery, activity, and mindfulness shape how Kova feels and reacts each day.
I'm Igor, and today I'm launching Habitvs - a tiny virtual pet for iPhone and Apple Watch whose mood is shaped entirely by your real Apple Health data.
Why I built it Most health apps shout numbers at you. Rings. Charts. Streaks that punish you for one bad day. I wanted the opposite - something that just cares. So I built Kova, a pixel companion who quietly reacts to how you're actually living. Move and sleep well, and Kova thrives. Burn out, and Kova gets a little worried.
How it works Kova has 5 moods - Lively, Rested, Balanced, Attentive, Concerned - driven by your activity rings, sleep, HRV, resting heart rate, mindfulness, daylight, and even wrist temperature. No goals to hit. No guilt trips. Just a small friend who mirrors your wellbeing.
What's inside • Native iOS + watchOS apps (SwiftUI + HealthKit) • Home Screen, Lock Screen, and Apple Watch complications - including a pixel-art "Retro" style • A weekly letter Kova writes to you, generated on-device with Apple's Foundation Models - nothing leaves your phone • Streak system with a weekly "shield" so one missed day doesn't break your momentum • Milestones at 3, 7, 14, and 30 days - including a crown for Kova • Customization: 7 colors, hats, glasses, bowties
Privacy Your health data never leaves the device. No accounts. No tracking. Ever.
I'd love your honest feedback - what feels delightful, what feels missing, and what would make Kova feel more alive. This is just day one.
the on-device Foundation Models for the weekly letter is a smart call - that's exactly the kind of feature that would feel creepy if it phoned home and delightful because it doesn't. how did you decide which health signals to weight most heavily for Kova's mood?
Hi Igor!
First off, I love the philosophy behind Habitvs. As someone with ADHD who appreciates a low-stakes way to stay mindful and active with some extra gratification from it, the idea of a virtual companion that mirrors your wellbeing rather than shouting numbers and guilt trips at you is so refreshing. The pixel-art complications are a nice touch.
I spent a little time with my Kova today (I named mine Goofy!), and I want to share some creative input that I hope will provide you with some decent feedback.
Onboarding Experience
Feature Tour - I think the app could benefit from a more in-depth guided tour upon first opening. A step-by-step walkthrough with info blurbs highlighting specific features would help new users feel oriented right away
Clarity on Stats - For example, I found myself wondering what exactly the energy bar represents at first
Deepening the Connection with Kova
Visual Evolution - I'm interested to see how Kova could change visually based on health data. Things like lack of sleep/not meeting a sleep goal reflect with little eye bags or other features of fatigue.
Moodlets & Check-ins - Having small "moodlets" appear while the app is open or doing occasional mood check-ins with Kova would make the relationship feel more interactive and two-way if that is your goal
Gamification & Customization
Activity-Based Rewards - I love the current customization, unlocking even more colors, hats, or accessories by hitting personal or app-based activity milestones would be a great motivator and gratifier. I think it would also increase the longevity of a user who may want to "collect" such items, especially if any were limited edition or only obtainable by specific goals and/or activities
Mini-Games - Adding small, health-related mini-games, like a 1-minute breathing exercise, brain-boosting games, or a quick movement challenge, could give users more ways to interact with Kova during the day
Streaks
If you're interested in leaning even further into the "no guilt" mindfulness vibe, consider a system that doesn't just protect streaks but prioritizes rewarding momentum. Continuing to reward positive progress, even if a day is missed, keep the focus on the journey rather than just a number without eliminating it completely. You already lean into this with the weekly shield, a feature I really like!
