The apps
Four tools. Pay once. Yours forever.
Every app is built the same way: pay once, own it for good, and everything stays on your device. The alternatives charge every month, forever — we think that's the wrong way to treat people.
Cradle
The smart baby tracker. Evidence-based nap-window guidance and pediatrician-ready reports — on your device, not in the cloud.
Power Nap
Naps built on real sleep science — the NASA 26-minute nap, the caffeine nap, and more — with gentle wake-ups and an Apple Watch companion.
VitalStack
Every supplement and vitamin you take, tracked in one place — with doctor-ready PDF reports for your next appointment.
DoseWorks
Reconstitution math and injection tracking, done carefully — so you never second-guess a dose.

Two we'll never charge for.
Our other apps are pay-once, and proudly so. These two are different — outdoor-safety apps we give away. Free forever, no ads, and Apple's "Data Not Collected" label. The same care as everything else we make, without a price tag.
Nearwater
Open-water safety for any US lake, reservoir, or river — real water temperature, wind, official National Weather Service alerts, and the nearest free life jacket. It'll even tell you if a river's running higher than normal. No verdict; the call is yours.

Miles Upstream
Flash-flood awareness for slot canyons — the rain and weather happening upstream of where you are, so you can see what's heading down the canyon before you drop in. Same principle as Nearwater: no go/no-go verdict, just the official signals.

Three promises, kept in every app.
Pay once
One fair price, up front — usually less than the subscription apps charge for a single month. No trials that trap you, no features held hostage. If we make it better, the update is free.
Private by design
Your data lives on your device and nowhere else. No accounts, no cloud, no analytics watching over your shoulder. Nothing to leak, sell, or breach.
Built by humans
A two-brother studio that answers its own email. Every app starts with real research into what people actually wish existed — then gets built with care.
