I want to build an app called "JXLCam". ## The Problem A Software Recommendations post explicitly asked for an Android camera app that saves photos as JPEG XL, noting that no mainstream camera app supports it despite the format being royalty-free and open-source. ## Target Audience Android power users, photographers, and storage-conscious users who want better compression without cloud storage fees ## Core Idea A camera app for Android that saves photos natively as JPEG XL for dramatically smaller file sizes without quality loss. JXLCam replaces the default Android camera for users who want to shoot directly to JPEG XL format, taking advantage of its superior compression, HDR support, and royalty-free open-source status. The app includes a batch converter for existing JPEG and PNG libraries and shows real-time estimated file size savings. Photos remain shareable to any app via standard Android media intents with automatic JPEG fallback when needed. ## Monetization Strategy Free with a $2.99 one-time unlock for RAW+JXL simultaneous capture and the batch converter ## Requirements - Category: E-commerce - Difficulty: Week - Suggested stack: Next.js + Shopify API or Stripe Please help me build this step by step.

I want to build an app called "KeyLatency". ## The Problem Keyboard latency testing is limited by how many keyboards an individual owns — the Lobsters keyboard latency probe creator explicitly recruited community help because three keyboards is not enough data, and no public crowd-sourced database exists. ## Target Audience Mechanical keyboard enthusiasts, competitive gamers, and developers obsessed with input precision ## Core Idea A crowd-sourced keyboard latency benchmark that lets you measure, compare, and publish your keyboard's true input lag from the browser. KeyLatency is a web app built around a standardized 3-minute browser-based latency test that collects anonymized results from participants, builds a searchable public database of keyboard models ranked by input latency, and lets enthusiasts compare switches, firmware versions, and USB polling rates. The Lobsters keyboard latency probe post highlighted that individual testers have only 2-3 keyboards to compare against, making crowd-sourcing the only viable path to statistically meaningful data. The leaderboard and comparison features create natural sharing and referral loops. ## Monetization Strategy Free public database with affiliate links to keyboards in results, plus a $5/year Pro tier for exporting raw data and private team benchmarks ## Requirements - Category: E-commerce - Difficulty: Weekend - Suggested stack: Next.js + Shopify API or Stripe Please help me build this step by step.
