BONKO Streamer
Desktop plugin plus iOS companion flow for streaming BONKO sessions, opening share links, and listening on mobile.
How do I get access?
Create a PTB account, claim BONKO Streamer products for free in the shop, and use your dashboard for the desktop download plus the iOS TestFlight link.
Where do I find the iOS app?
The iOS product opens from your dashboard via its release link after you have claimed it.
The stream does not connect. What should I check?
Make sure the desktop BONKO Streamer is running, the URL or share link is correct, and both devices can reach the streaming endpoint. If the issue persists, send your setup details to support.
Key - Music Detection
Real-time note, chord, and key detection. Includes chromatic tuner, guitar tuning presets, BPM tap tempo, and drone tone generator.
Why does the app need microphone access?
Key Detect uses your microphone to analyze audio in real time. All processing happens locally on your device — no audio is recorded, stored, or sent anywhere.
What is included in Pro?
Pro unlocks Guitar Tuning Presets, BPM Tap Tempo, and the Drone Tone Generator. Note, chord, and key detection plus the chromatic tuner are always free.
How do I restore my purchase?
Go to the Store tab inside the app and tap "Restore Purchases". Make sure you are signed in with the same Apple ID you used for the original purchase.
Detection seems inaccurate — what can I do?
For best results, play in a quiet environment with the microphone close to the sound source. Single notes and simple chords work best. Complex polyphonic audio (full mixes) may reduce accuracy.
BPM Counter
Simple, accurate tap tempo BPM detection. Tap along to any beat to find the tempo.
How accurate is the BPM detection?
The app calculates BPM from your tap timing with high precision. For best results, tap consistently for at least 8 beats.
