Neumeral Blueprints
Don't start from scratch. Start with sane defaults.
A gallery of buildable app blueprints — mobile, web, and full-stack — each backed by a downloadable starter repo built on the exact stack we ship for clients. Clone a working app, then let us take it to production.

25+App Ideas
How it works
From repo to production in three moves.
01
Browse the gallery
Curated, validated app ideas — each mapped to one of 10 production-grade mobile and web archetypes.
02
Download the starter repo
Clone a repo that boots with mock data on first run — no backend required to see it work.
03
Ship it with Neumeral
Wire the auth, backend, and deploy — book a build sprint and take it to production.
The repo hub
10 Kits. One repo each.
Every idea collapses into a technical archetype — so we build 10 strong repos, not 25 weak ones.
