Same. Have had great results with it. I got sick of paying FreshBooks monthly for basic income/expense tracking for Schedule C reporting and used GSD to build a macOS Swift app with Codex 5.4 and Opus 4.6. It’s working great and I am considering releasing it on the App Store. It started as a web app, but then I wanted screen capture from other windows for receipts in email or whatever. Then I wanted physical receipts, and so used Apple continuity camera. All working now in my app. And, I just added receipt auto-extract to pull salient info from and determine deduction category using Anthropic API.

Yes this is how much paying FreshBooks annoyed me. Plus I hated they forced an emailed 2FA if you didn’t connect with Google.
