As answered by people managing Airmail 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.

The airmail app https://airmailapp.com has a shortcut action that allows you to search emails and returns things, not used it myself but you could try that. Source: over 3 years ago
I once trusted AirMail, but they created so many extra folders and kept switching around the client interface. It haunts me to this day, since I recommended it to so many people who hated it. Source: over 3 years ago
You might want to consider Airmail Pro or Business as an alternative. I think it has all the features you are looking for. They offer a privacymode and some privacy features but I don't have any experiences with this app or company. Good... Source: over 4 years ago
