You can record and send voice notes to your clients directly from the FitMetrics message composer — no need to switch to the Trainerize app.
How to Send a Voice Note
Open Trainerize Messages and select a client conversation
Click the microphone icon in the message composer
Your browser will ask for microphone permission — click Allow
Start speaking — you'll see a live timer showing the recording duration
Click the stop button when you're done (maximum 5 minutes per recording)
The voice note is automatically converted and sent to the client in Trainerize
The client will see the voice note as a playable audio message in their Trainerize chat.
Requirements
Browser: Chrome, Firefox, Edge, or Safari (latest versions)
Microphone: A working microphone (built-in or external)
Permission: Browser must have microphone access enabled for FitMetrics
Max length: 5 minutes per voice note
Common Issues & Fixes
Error: "Microphone access is not supported in this browser"
Your browser doesn't support audio recording. Update to the latest version of Chrome, Firefox, Edge, or Safari.
Error: "Please use the Trainerize mobile app or a browser that supports SharedArrayBuffer"
This means the audio format conversion (needed for Android playback) isn't available in your current browser. Try:
Using Google Chrome (best compatibility)
Clearing your browser cache
If on a corporate network, ask your IT team about Cross-Origin headers
Error: "Could not convert audio format"
The audio conversion failed. Try:
Recording a shorter message
Refreshing the page and trying again
Using a different browser
Microphone Not Detected
If clicking the microphone icon does nothing:
Check your browser's address bar for a blocked microphone icon
Click it and select Always allow for FitMetrics
Check your computer's System Preferences / Settings → Privacy → Microphone — make sure your browser is allowed
Try a different microphone or headset
Voice Notes in Coaching Notes
You can also record voice notes in the Notes panel (not sent to clients). These are automatically transcribed to text by AI and added to your notes. Great for quickly dictating observations during client reviews.
