Mobile apps
Native-quality iOS apps built with React Native and Expo — dev builds, native modules, App Store delivery. We ship our own app this way, so we know where the landmines are.
New Hampshire · Products & contract work
Software built to work in the field.
Double Tap Software is a small New Hampshire software company. We build our own products — starting with Brow Tine, a hunting-maps app that has to keep working with no signal in the woods — and we take on contract work across the same stack: mobile, mapping, and cloud.
The flagship: Brow Tine
Our own product, and the proof of how we build. A deer-hunting maps app for iOS, New Hampshire first.
The deer hunter's map.
Every hunting app maps public land. Brow Tine exists for the two things they all do badly: live party location for the deer drive, and offline maps that actually work when there's no signal. Under the hood: 617,124 property boundaries compiled into vector tiles, a Cloudflare backend, and a map that never sits behind a login.

- Cloudflare Workers, D1 and R2 end to end
What we do
The same stack we bet our own product on, available for yours.
Maps & geospatial
MapLibre, vector tile pipelines, offline map packs, parcel and GIS data wrangling. Turning messy public GIS sources into fast, correct map layers is our home turf.
Cloud backends
Cloudflare Workers, D1, R2, Durable Objects — serverless backends that cost almost nothing at rest and scale when it matters. Auth, APIs, data pipelines.
Web
Fast, static-first sites and web apps — Astro, TypeScript, Tailwind. No bloat, no third-party trackers, scores that hold up in Lighthouse.
Contract engineering
Available for contract work across the stack we use ourselves. Small, senior, and direct — you talk to the person writing the code.
How we work
Products first
We build and ship our own software. Contract clients get the same habits that keeps a product alive in the wild: honest data, offline resilience, and no feature that lies to the user.
Boring where it counts
Proven tools, narrow dependencies, infrastructure that costs almost nothing at rest. The exciting part should be what the software does, not whether it stays up.
Senior and direct
No account managers, no handoffs. The person you talk to is the person writing the code, and the codebase is one you could take in-house tomorrow.
