levin.schwab@gmx.de→Is it a subscription?+
No. MixGrade is a one-time purchase of €9.99. Three full analyses are free so you can try everything first.
Does my mix get uploaded?+
No. Analysis runs entirely on your iPhone. Optional track identification sends only audio fingerprints to Apple’s Shazam service, never your recording.
What formats are supported?+
MP3, M4A, WAV, AIFF and FLAC, with sets up to three hours long.
How do I restore my purchase?+
Settings → Restore Purchases inside the app. Make sure you are signed in with the same Apple ID you bought Pro with.
Why are some tracks shown as “Unknown Track”?+
Track identification relies on the Shazam catalog. Unreleased or heavily edited tracks will not match, but the analysis itself (beatmatching, keys, energy, levels) still works on the audio.
