Here's Perfect Recorder UWP in action:
Setting the app up - there are half a dozen sample rates to choose from. Note the OneDrive sign in, this enables one tap upload/backup, once authenticated; (right) Recording in progress, you can pause/resume, stop and put in 'lap' markers (which appear visually when playing back in the app)...
Saving to wider storage in the phone, uploading to OneDrive, it's all quite flexible; (right) not much to see on the main menu. Note that 'pin' here is 'pin to start', not to be confused with putting a PIN or password on your recordings!
You can grab this in the Store here. There's an in-app-purchase to get rid of ads, if you want to support the developer.
