App project brief generator
A project brief is the one page a developer or agency can quote from: who the app is for, the problem it solves, what must ship first, the budget band and the deadline. Fill in the fields and the generator writes the brief as Markdown you can copy, download, or send to us as an enquiry.

# PhysioBook — project brief > Lets patients book and pay for physiotherapy sessions at independent clinics, and gives clinics one calendar for every therapist. ## Who it is for - Patients booking sessions - Therapists managing their day - Clinic owners viewing bookings and payouts ## The problem today Clinics take bookings by phone and WhatsApp, double-book therapists, and chase no-shows for payment. ## First release: must have - Patient sign-up with phone OTP - Book a slot with a chosen therapist - Pay online when booking - Reminders by SMS or WhatsApp - Clinic calendar for all therapists ## Later: nice to have - Session notes and exercise plans - Packages of 5 or 10 sessions ## Constraints - Platforms: Web app plus iOS and Android apps - Starting point: A new idea, nothing built yet - Must connect to: Razorpay, an SMS or WhatsApp provider, Google Calendar - Users in: Bangalore first, then other Indian cities - Budget band: ₹5–15 lakh / $6,000–18,000 - First release live: Within 4 months ## How we will know it worked 200 bookings a month through the app across 5 clinics, 3 months after launch. ## Open questions for the developer - Which of the must-haves is the riskiest to build, and why? - What would you cut to hit the deadline at this budget? - What will it cost to run each month (hosting, SMS, maps, payments)? - Who owns the code, the accounts and the app store listings at the end?
Discovery Sprint: ₹1,50,000 / $2,900
A brief is the input to a Discovery Sprint: two weeks that turn it into user flows, a clickable prototype and a fixed-price quote for the build.
What goes into an app project brief?
A good brief answers the questions every developer asks before quoting: who uses the product, what they do today and what goes wrong, which features must ship in the first release, and the limits the work has to fit (platforms, integrations, budget, deadline).
The split between must-have and later matters most. Developers price the first release, so a long must-have list raises every quote and pushes back the launch. If a feature could wait until the product has real users, it goes under later.
The brief ends with a success measure and four questions to ask whoever quotes. The answers show whether a developer has thought about risk, running costs and ownership, not just the build.
