Flutter Dev needed - Safety App - Fixed Price- UK solo Dev Only

hi
I need a Flutter developer for V1 of an app

no agencies, solo developer only who codes in Flutter daily.

what is it -
a safety anchor app, simple on the surface, serious underneath.
one button that says always
PIN entry, encrypted notes/voice notes, a check in timer

i have the full flow, spec and design language ready, no guess work.

stacks
flutter + firebase + local encryption (hive/ encrypted box) android + ios

what i need for V1

onboarding and PIN
home with always anchor
encrypted notes + voice capture
check in timer / logic
clean calm UI - no stock no fluff
NDA signed

budget
800 -1200 price for v1 prototype
if we work well V2 is next
