App Development for User-Interactive Letter Sending Platform (Unity-Based)
Budget: €750 – €1,500 EUR
We are seeking a skilled and passionate mobile app developer to bring to life an innovative project designed to provide encouragement and support to users facing life’s challenges. This iOS and Android app, built using Unity, will allow users to send letters to a central database and receive thoughtful, uplifting responses, fostering a safe and positive digital space.
?About the App
The core functionality of the app revolves around anonymous letter writing, where users can share their thoughts and receive messages of encouragement in return. To enhance engagement, the app will incorporate customizable 3D avatars—adorable, stylized characters that users can personalize with different outfits, hairstyles, and accessories.
?Target Audience
This app is designed to support individuals who may be experiencing:
? Mental health challenges such as depression, anxiety, or loneliness
? ADHD or neurodivergence, benefiting from a structured but engaging digital support system
❤️ Anyone in need of encouragement, reassurance, and connection
The goal is to create a comforting, non-judgmental, and uplifting environment where users feel seen, supported, and valued.
?Design & User Experience
The app will be designed to evoke a sense of calm, warmth, and positivity, ensuring an intuitive and accessible experience for all users.
?️ Aesthetic: Cute, cozy, and visually appealing—reminiscent of Animal Crossing-style avatars.
? Music & Atmosphere: Relaxing, lofi-inspired background music to create a soothing experience.
??User-Friendly UI: Designed with accessibility in mind, featuring a clean, minimalistic interface that is ADHD-friendly and non-overwhelming.
? Customization & Unlockables: Users can personalize their avatars and unlock new outfits, accessories, and styles over time.
?️ Technical Requirements
We are looking for a developer with experience in:
✅ Mobile app development (iOS and Android)
✅ Unity development (ensuring all features can be integrated and modified within Unity)
✅ Database management (secure storage and retrieval of user messages)
✅ 3D avatar integration (supporting customizable character models)
✅ User-friendly UI/UX design (ensuring smooth, engaging interactions)
✅ Familiarity with monetization options (for optional unlockable content) is a plus
?️ Development & Flexibility
The app must be built in Unity, allowing for future edits, expansions, and updates.
The 3D avatars and customization system should be fully editable within Unity, so that new features, outfits, and items can be added over time.
A well-structured, modular approach to development is preferred to ensure flexibility and scalability.
