NeuroSprint — The daily brain benchmark - A daily 6-minute brain benchmark you race with friends

Three brain-training events, two minutes each, every day. Everyone plays the same daily challenge, so your Brain Score comes with a real top-% rank against everyone who played today — not a score in a vacuum. When you finish, you get an emoji grid to share (think Wordle) and can challenge a friend to beat it. No signup to try. Built for people who bounce off single-player brain apps and want a reason to come back daily.

Ghost Comment - Anonymous feedback widget. One line of code.

Anonymous feedback widget you add with one line of code. No login, no name — just honest feedback. I built 42 apps in 3 months but never knew what users thought. So I built this: paste one script tag, a 👻 button appears, users share feedback anonymously. - 50KB widget (HTML/React/Next.js/Vue) - Dashboard + CSV export - Claude AI sentiment analysis (Pro) Free: 30/mo. Pro: $7/mo. Built solo, $0 budget.⁠
