About

An independent app studio

Native iPhone, iPad and Mac apps, designed, built and supported by one developer.

umay.dev is the independent app studio of Buğra Günay, a solo iOS and macOS developer based in Türkiye. Every app here is designed, built, published and supported by the same person, and has been since the first release in 2020.

The current apps cover short-form video creation (Brolled), cinematic color grading (Cinegrade), private mood journaling (ShadowART), voice and speaking reflection (Fenno), game theory decision games (MindType), personal supplement experiments (SuppLab), a calendar assistant for dads (Cornerman) and WiFi-based home monitoring and automation for Mac (Pulse Guard and Pulse Home).

The apps are written natively in Swift and SwiftUI. Where a feature can run on the device, it does: several apps use Apple frameworks such as Core ML, Speech and Vision locally, and some have no accounts or servers at all. Data handling differs by app, so each one links to its own privacy policy.

Questions, bug reports or press: experlercom@gmail.com. More about the developer on the about page.

How We Work

Our approach to building products

Four principles guide everything we design and ship. These aren't just words on a wall — they're encoded into every line of code, every design decision, and every product release.

🔒

Privacy by Design

Your data stays yours. ShadowART processes all emotional data on-device using Apple Core ML and the Natural Language framework. Pulse Guard analyzes WiFi signal changes locally on your Mac. Some apps offer optional sync or connected features. Check each app’s privacy policy and settings for details.

🎨

Design-First

We obsess over every pixel, every animation, every micro-interaction. From ShadowART's calming archetype cards to Pulse Guard's real-time monitoring dashboard, every screen is designed to feel intuitive from the first tap. Beautiful enough to show off, simple enough to use without a tutorial. We believe great design is invisible — it just works.

⚡

Ship Fast, Iterate

We believe in launching early and iterating based on real user feedback. Every app goes through Apple TestFlight beta testing before public release. App Store Connect analytics and user feedback help us identify which features users engage with, guiding development roadmaps and prioritizing what matters.

🤖

AI That's Useful

On-device sentiment analysis and NLP for journaling in ShadowART, game theory algorithms based on Nash Equilibrium and Prisoner's Dilemma in MindType. We make AI accessible, private, and genuinely useful — not a marketing buzzword, but a core product feature.
