Preparing Equalizer for launch: how we ship an app to the App Store
At VOIO we're preparing to release Equalizer — a music player with a professional 16-band equalizer, bass booster, 3D sound and a live visualizer. It's the sixth app in our portfolio, and over the years we've built our own launch checklist. Here it is — useful for anyone shipping a product to the App Store.
1. TestFlight: testing until the last build
Before release the app goes through several TestFlight waves: first the internal team, then a closed group of external testers. For an audio app it's critical to test different output devices — wired headphones, AirPods, Bluetooth speakers, CarPlay. That's where we caught most of the audio-processing latency issues.
2. Privacy labels and permissions
Apple requires an honest declaration of what data the app collects (App Privacy "nutrition labels") and a working privacy policy link. Equalizer processes audio locally on the device, so our principle is simple: collect the minimum, declare everything.
3. ASO metadata
The name, subtitle and keywords are prepared in advance and localized for key markets. In 2026 Apple even indexes the text on screenshots, so captions are a full part of search optimization — not just design.
What goes into our launch ASO package
- A name and subtitle targeting the market's main search queries
- Screenshots with captions for every key feature
- A preview video demonstrating the equalizer in action
- Store page localization in at least five languages
4. Launch day
We set the release to manual publishing after review passes: this lets us pick the day and sync announcements. The first week matters most: fresh ratings and reviews strongly influence how a new app ranks.
Launch isn't the finish line — it's the start of iteration: the first user reviews define the backlog for months ahead.
Stay tuned — Equalizer will soon appear on our project page with an App Store link.
