We build apps differently.
No accounts. No ads. No data collection. No internet required. Your information stays on your device — always.
Private by design
Zero analytics, zero telemetry, zero third-party SDKs. We can't see your data because we never collect it.
Works offline
Our apps never connect to the internet. They work anywhere — airplane, gym, middle of nowhere.
Fair pricing
Free trials on every paid app, and some apps are simply free. Plans from $0.99/month — we charge a fair price instead of selling your data.
You're in control
Export your data anytime. Delete everything with one tap. Uninstalling removes all traces.
Built with you
Your feedback shapes every update. Tell us what's working, what's not, and what would make your life easier. We read every message.

We're a small studio building privacy-first apps for health and wellness. Our mission is simple: build thoughtful software that genuinely improves people's lives. Every app we make works offline, collects no data, and puts you in control. No venture capital, no growth hacks — just careful work by people who care.
The best way we know if we're getting it right is hearing from you. Whether it's a bug, a feature idea, or just a kind word — we'd love to hear from you.
