Final deliverables #

Project overview #

Solar Wind is a social matching iOS app designed to connect people based on shared sports and fitness interests.

Problem statement: Staying consistent with a workout routine is tough — but having a reliable partner makes it easier. Solar Wind solves this by helping users find nearby people with similar fitness goals, interests, and availability. Unlike generic meetup platforms, Solar Wind is focused entirely on building a sport-oriented community with personal matching.

Target users: Young adults (18–30) who want to stay motivated and find compatible workout partners.

Key features:

• Filling out the profile: Users specify their city and favourite sports.
• Matching: Feed suggests other users from which user can choose his partner.
• Contact with matched people: After users matched with each other, they can redirect to Telegram chat.

Features #

1. Verification via Telegram

   • @SolarWindAuthorization_bot sends a code for athorization after user’s “/start” message.

2. Filling out the profile:

   • search for a city by the first letters in the search bar.
   • search for a specific sports by the first letters in the search bar or choose from a list.
   • specify the user’s name and write something about himself in a specific field.
   • specify the user’s gender and birthdate.

3. Matching:

   • a feed in the main page with other users.
   • user can like other users they like.

4. Contact with matched people:

   • if users’ like is mutual, a button leading to Telegram appears on the notification page.

5. Additional features:

   • Change of language (RU/EN).
   • Change of theme (dark/lite).
