Aporix

Platform connecting idea owners with developers, with built-in market validation. Visualises empathy count as a demand score. Now available on the App Store.

Aporix is an idea-sharing platform: people post ideas, others tap to signal they want them built, and developers browse ranked by that signal. It shipped to the App Store in April 2026.

The structural decision was a Turborepo monorepo rather than separate repositories. The Expo mobile app and the Next.js web app share three packages — db (Supabase client, generated types, table constants), features (React Query hooks and Zustand stores) and ui (Tamagui components). Adding a field is one edit propagated by the type system, instead of a race between two codebases that would have drifted within a week.

Data sits in Supabase — PostgreSQL with row-level security and realtime subscriptions — so authorisation lives next to the data rather than being reimplemented per client. Subscription entitlements go through RevenueCat, which keeps receipt validation and cross-platform restore out of application code.

Shipping to an app store demanded a rigour that web deploys never teach. Privacy disclosures have to match what the code actually does. In-app purchase flows must be exercisable by a reviewer whose sandbox does not behave like a real account. User-generated content needs a moderation path on day one, not bolted on after the first incident. None of this is surprising in hindsight; all of it is invisible until the first rejection.
