An independent software studio

Small, thoughtful softwarefor everyday life.

Nintek builds focused apps that each do one thing well — for learning, health, home, and play. Tenof them so far: six with current web builds and seven with native iOS work at clearly stated release stages. Tare also includes an Apple Watch app; no page implies public store availability without evidence.

The direction

Nintek is going native.

7 products now have native iOS builds in SwiftUI or Godot. None has a public App Store listing today: Tare, Workshop, Cortex, and Sortie are internal TestFlight builds; Cairn is blocked after review; ShopKeep has a private attached build; and Salvo remains unreleased.

Health & Wellness

Every number tells a story.Read the trend.

Weight, doses, glucose, labs and well-being on a GLP-1 journey — read together, not in four separate places. The native build automatically imports approved Apple Health data when the app opens or returns, supports iPhone, iPad and Apple Watch, and needs no account.

About Nintek

I'm an SRE by trade and a maker by habit. These apps grew out of problems I was already living with — tracking a health journey, keeping a woodshop in order, staying certified at work, winding down with a daily puzzle, and running a home without losing the manual in a drawer somewhere. Each one started as a note, then a prototype, then something I couldn't stop using. Nintek is where they live.
