Product engineering studio · Cheyenne, Wyoming

We build software
that moves things forward.

Impeltech is a compact team of engineers. We design, build and run our own products — AI app builders, cross-platform planners, the infrastructure underneath — and we do the same for the people who hire us.

Our products

Two products we own end to end —
from the first commit to the invoice.

Flangapp AI

No-code app builder · sold on Envato Market

Turn any website into a native iOS and Android app by describing it in plain language. Flangapp is a self-hosted SaaS script: our customers install it on their own server, add their pricing, and sell mobile apps to their own clients — subscriptions or one-time.

  • AI configurator
  • Push notifications
  • White label
  • Billing built in

Plan B Planner

Weekly planner · iOS, Android, macOS, Windows

A planner for people who actually plan. Tasks and habits for the week, life dimensions that fill up as you go, a focus timer, shared boards, and an assistant that reads a photo or a link and turns it into a task. One Go backend, four native clients.

  • Habits & streaks
  • AI task capture
  • Offline-first
  • Cross-platform

What we do

Small team, whole stack.

No handoffs between departments — the same people design the screen, write the API and keep the server alive at 3 a.m.

Mobile apps

Native Android in Kotlin and Compose, iOS in Swift and KMP. Shipped through the App Store, Google Play and TestFlight — release pipelines included.

Backends & infrastructure

Go and PostgreSQL behind nginx, in Docker, with migrations, backups and monitoring. We run our own servers, so we know what breaks.

Desktop software

Compose Multiplatform for macOS and Windows from one codebase — signed, notarized, self-updating, on the Mac App Store and as an installer.

AI where it pays off

LLMs wired into real workflows: turning a page into an app, a screenshot into a task, a sentence into a schedule. Useful features, not demos.

The studio

Engineers who also own the product.

We are programmers first. Every project here is written by the people who decide what it should become, which is why our releases are small, frequent and boring — in the good sense.

We pick current tools and keep them current: Go on the server, Kotlin and Swift on devices, Compose Multiplatform on the desktop, LLMs where they earn their keep. Nothing is outsourced, nothing is a black box.
