What we ship

Recipes, not prompts: one edge in front of every app

Valid JSON, junk inside: guarding model output before users see it

About

An independent studio

shpapps is Francesco Noferi, an independent developer in Tuscany, Italy, building small mobile apps with an obsession for feel: fast answers, honest pricing and motion that makes sense.

Questions, bugs or ideas: hello@shpapps.dev.

  • One job, done well. Each app solves one problem end to end instead of growing a menu of features.
  • No sign-up walls. Open the app and use it. No account to create first.
  • Motion with a purpose. Animation explains what just happened. It never makes you wait.
  • Prices you can read. What you pay and what you get, on one screen, before you pay.
