About TheCozyDev

TheCozyDev is my one-person iOS studio making calm, cozy apps that give you a little room to breathe. I'm Em. I didn't come from a traditional dev background. I taught myself Swift and SwiftUI by building things alongside my 9–5, rather than waiting until I felt ready. I make gentle tools for everyday moments. Cozy Pom is for calmer focus, MochiMoney is for small money moments without the anxiety, and Lumarii is a private journal that notices rather than keeps score. Next up is wumbl., a calm macOS world with living Spaces, ambient sound and a little computer friend called Wumbl. I create for people who want technology to feel softer: anyone who's overwhelmed, building after hours, or craving a kinder corner of their screen. For beginner developers, my Ship Your First App Kit helps you get through App Store submission, because if I can ship, so can you. Cozy isn't just a look. It's a promise to make things that feel like a deep breath. 💜

A NOTE FROM THE FOUNDER

I didn't start out as a developer. I never had a computer science degree or a tech job title, just a 9–5, a laptop and a feeling that apps could be gentler than most of the ones on my phone. So I started learning Swift and SwiftUI the only way that made sense to me, by making things. I didn't wait until I felt ready, because I'm not sure that feeling ever comes. I built in the evenings after work, one small step at a time, usually with a coffee beside me. My first app was Cozy Pom. It began as a simple Pomodoro timer and slowly grew into a calmer focus app, with focus sessions, themes, journalling, ambient sounds and Live Activities. There are no ads, no accounts and no subscription. I put more than 400 hours into it, and seeing it go live on the App Store is a moment I'll never forget. After that, things started to move. MochiMoney started as a tiny calculator idea and reached the App Store less than two months after Cozy Pom. It's an everyday money companion for small moments like splitting a bill or keeping an eye on a savings goal, without the anxiety. Then came Lumarii, a private journal that notices rather than keeps score. That made three apps shipped in 2026, all built after hours. In August I launched thecozydev.co.uk to give TheCozyDev a proper home. Because the App Store submission process nearly broke me the first time, I made the Ship Your First App Kit, so beginner developers don't have to work it out alone. Now I'm building wumbl., a calm macOS world with living Spaces like Morning Café and Rainy Window, an ambient sound mixer, focus sessions and a small computer friend called Wumbl. TheCozyDev is proof that you don't need the perfect background or the perfect timing. You can start where you are, build slowly and make things that feel like a deep breath. If I can ship, so can you. 💜
