Building an App for birthday itinerary planning

I have built a complete app for one of my client from just the brief description provided to me. The app includes the following features:

Stunning UI with elegant and simple to use UX , easy to navigate and use app with constant theme and color.

The app provided seamless, upscale birthday experience for the recipient which made them feel as if every moment of their day is curated just for them.

Integration with Maps and Transportation: The app will be closely integrated with mapping services. Allowing users to be effortlessly guided from one experience to the next.

Venue Recommendations: The platform recommends high-quality experiences based on the user's location, ensuring only top-notch venues are suggested.

Personalized Experience through QR Code: Upon scanning the QR Code from the envelope, the birthday recipient will be prompted with personalized questions that guide the experiences we've pre-selected for them.

Time-Limited Invites: Users can send out 24-hour access codes to friends and family, allowing them to join in on the festivities. These codes should be one-time use and expire after 24 hours.
