I am developing a mobile application called SPARR, designed to connect combat sports practitioners with suitable training and sparring partners in their area. The core interaction is based on a swipe system similar to Tinder, but the focus is entirely on combat sports. I will provide visual reference screens to demonstrate the intended look and user flow. These references are for orientation only — the app must be developed cleanly and professionally from scratch. The application will consist of four main sections: 1 – Home (Swipe Feed) Users can swipe profiles right (like) or left (skip). Each profile includes multiple images (visible via scroll), and displays: Name, age, height, weight, sport(s), experience level (1–10), distance, optional gym, and a short bio. Filtering options: age, height, weight, sport, gender, distance, experience level. Blocking and reporting must be possible directly from the profile card. 2 – Matches & Chat If two users like each other, a match is created. A real-time chat enables communication between matched users. Blocking and reporting also available here. 3 – Trainer Section Trainers can offer paid training sessions (with pricing, availability, location). Athletes can also post training requests. Ratings and reviews apply only to trainers — and only after a confirmed training session. 4 – Settings Profile editing, default filter configuration, management of blocked users, private mode (profile hidden from feed), full account deletion (including complete data removal).
