As answered by people managing Digital Logic Sim and ClientForms.app.
ClientForms.app's answer:
Frontend: Next.js 15 (React 19), Tailwind CSS Backend: Supabase (PostgreSQL, Row-Level Security) Authentication: Clerk Payments: Stripe Hosting: Vercel (Sydney region) Database hosting: Supabase (Australian data residency)
ClientForms.app's answer:
Psychologists who assess ADHD and autism. Typically private practice, solo or small group (1-5 clinicians), currently using paper forms and spending hours on admin per assessment. They want something that works and is secure.
ClientForms.app's answer:
Neurodivergent-first design. Most digital forms just replicate paper online. ClientForms is built specifically for ADHD and autism patients - progress bars with time remaining (helps with time blindness), softer colours instead of harsh white, sticky headers so you always know where you are. The forms are designed to reduce anxiety and improve completion rates.
ClientForms.app's answer:
Most clinical software treats patients as an afterthought. ClientForms is designed specifically for neurodivergent users who are filling out the forms, progress indicators, time estimates, calmer colours, predictable layouts. One link, no signup required, works on any device. Patients just open and complete.

Reminds of Digital Logic Sim by Sebastian Lague, which I really like as you start with just a NAND gate and go from there. https://sebastian.itch.io/digital-logic-sim. - Source: Hacker News / 4 months ago
When I first opened the page, I thought this was just a knockoff of the "Digital Logic Sim" by Sebastian Lague [1], but watching the video, I was impressed by how much deeper this actually went. So I bought it! Hopefully I get some time... - Source: Hacker News / almost 3 years ago
