Who builds Macdio
Macdio is a solo-developer project by Sait Firat NEMIS. There is no company behind it, no team, no investors. Just one person building a radio app that felt missing from the App Store.
I handle the SwiftUI code across all six platforms, the website, the App Store presence, and the support inbox. If you email support@devdio.pro, you are reaching me directly.
How it is built
Macdio is 100% native Swift and SwiftUI. No Electron, no React Native, no web views. Every screen is written specifically for the platform it runs on: iPhone, iPad, Mac, Apple TV, Apple Watch, and CarPlay.
Like most developers in 2026, I use modern AI-assisted tools as part of my workflow, for exploring edge cases, prototyping ideas, and working through tricky debugging sessions. But the core architecture, the design decisions, the performance tuning, and the final shipped code all come from deliberate research and hands-on iteration. I care about getting the details right, and that means understanding every layer of the stack rather than accepting whatever a tool generates.
Data sources & APIs
Macdio does not curate a station catalog of its own. Station listings come from Radio Browser, a public community database, with Macdio's own copy of it (dir.macdio.app) used only when Radio Browser does not answer. Now-playing metadata and lyrics come from public APIs. Here is what the app talks to:
Radio Browser
Community-maintained database of internet radio stations. Provides station metadata, stream URLs, country info, and genre tags. This is where the catalog of tens of thousands of stations comes from.
radio-browser.info ↗iTunes Search API
Apple's public search API, used to enrich now-playing information by fetching album artwork, release year, and album name based on the track metadata that radio stations broadcast.
iTunes Search API ↗LRCLIB
Open-source, free lyrics API. Provides synchronized (LRC format) and plain-text lyrics for the currently playing song. No API key required, no tracking.
lrclib.net ↗Podcast Index
Open, independent index of 4.7 million podcasts. Powers podcast search, charts and categories. Episodes and feeds then download straight from each show's own server.
podcastindex.org ↗Apple ShazamKit
Apple's song recognition. Song ID sends a short audio signature of the stream, never a recording and never the microphone, and gets back the song, the artist and the cover.
ShazamKit ↗push.macdio.app
Macdio's own notification server for new episodes. Only when you turn notifications on, it receives the device's notification address and the shows you follow, and nothing else.
Privacy policyDependencies
Macdio has a minimal dependency footprint. The app itself uses zero third-party Swift packages. It is built entirely with Apple's own frameworks (SwiftUI, SwiftData, AVFoundation, CloudKit, MediaPlayer).
This website is just as lean. It ships with no web fonts and no 3D libraries. Typography uses the system font already on your Apple device, and every animation is plain CSS and JavaScript. The external services are:
| Name | Purpose | Type |
|---|---|---|
| Umami | Visit counting without cookies, plus session replay and click heatmaps for about 15% of visits, on the developer's own server at stats.devdio.pro (website only) | Web |
| Radio Browser | Station data for the directory page, queried from your browser (website only) | Web |
| dir.macdio.app | Macdio's own copy of the Radio Browser directory. The directory page asks it only when Radio Browser does not answer. It keeps no IP addresses. | Web |
| hub.devdio.pro | Macdio's own community forum. The "New" badge on the logo asks this site's own server for the three newest release notes; your browser never contacts the forum, and the only thing kept is the id of the last post you saw, in your browser's local storage. | Web |
| Station logo servers | On the directory page each station logo is loaded from that station's own server, so those servers see your IP address. The requests are sent with no referrer, and a logo that fails to load is replaced with a local glyph. Nothing is proxied through this site. | Web |
