I developed the front-end mobile app and the back end (Azure App Services using Node.js) for this social planning app.

Yallapp is an app that makes planning activities and occasions with friends and family way easier. It's free and feels like any other way you plan your activities or respond to others, but it is way more practical.

No more creating groups on chatting applications, texting back and forth, or scrolling through endless conversations to find who is going where and when. Yallapp covers it all.

Yallapp allows users to plan their activities and events with friends in a few clicks. Here's what you can do using Yallapp:

Create — Do you feel like going out, planning a party, or a gathering? With Yallapp, you can create a plan in less than 30 seconds that your Yalla friends will know about or invite them through SMS, having all the details and the link to download the app.

View Plans — Know who's in and out, edit details anytime, chat with friends, add it to your calendar, and much more. All features have been carefully designed for users to view plans in a friendly, practical way.
