Some of the projects I've been working on include: 📱 NotLate – A wellness app designed to help with overthinking and restless nights. 💰 ZapSpend – An expense tracker with receipt scanning, voice input, and CSV/PDF exports. 🚛 Trucker Diary – An iOS app built for truck drivers. 🎵 Duo Vinyl – A digital vinyl turntable experience for music lovers. As a solo developer, one of my biggest challenges isn't just building products. It's getting them discovered, attracting users, and figuring out what actually works after launch. 🌐 https://www.adribyte-studio.com/mobile-apps #IndieHacker #IndieDeveloper #iOSDevelopment #SaaS #Startup
