Cards are cleaner, Pro features are marked with a simple badge instead of a lock icon, and the whole app has a more polished, professional look. The biggest addition is a brand new AI Tools section. Beyond the existing AI Assistant for code questions, there's now **AI Job Pricing**, which lets you describe any job in plain English and get an instant price estimate based on your labor rate, local market rates, and material costs. There's also **AI Scope of Work**, which generates a professional job document you can hand to a customer or GC before starting work, and **AI Customer Message**, which writes polished texts or emails for you — pick a tone (professional, friendly, firm, apologetic) and it handles the wording so every customer interaction sounds professional, even on a rough day. We also added "Ask AI" buttons throughout Code Reference, Study Prep, and Facts of Life, so if you're reading a code section or studying a topic, you can tap once to get an instant AI explanation without leaving the screen. On top of new features, this build fixes several bugs from the previous release: AI Scope of Work and AI Customer Message weren't functioning at all in earlier builds due to a backend issue — that's now resolved. AI responses across the app now display in clean, readable text instead of raw formatting symbols. A crash when generating a new customer message is fixed, and the "Ask AI" buttons inside Copper Practical Prep, which were silently broken, now work correctly. Water Heater Troubleshooting is now correctly restricted to Pro members as intended, and free users are capped at 10 practice questions per day. ### 1.0 — 2026-05-13 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
