As answered by people managing X-Plane 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.

X-Plane and FlightGear are easily the most realistic but also the most complex. X-Plane costs $59.99 whereas FlightGear is free but X-Plane is more polished and easier to get going with than FlightGear.

Haha, yes I know I can just buy it from x-plane.com, but I was just wondering what the community had to say. Source: about 4 years ago
Has anybody gotten the "transaction failed (error 47)" message when trying to check out on x-plane.com? I've been trying to buy XP12 and I repeatedly get hit with this message :(. Source: about 4 years ago
