I first covered Just Press Record in September. Primarily positioned as the missing voice recorder for Apple Watch with fast performance thanks to watchOS 2, the app is also a capable voice recording utility for iPhone that makes it easy to save files to iCloud Drive.
The latest 1.2 update to Just Press Record has added 3D Touch support with a shortcut to start a new recording from the Home screen (also available in Apple's app), plus peek and pop actions to preview the contents of each folder. The latter is useful because Just Press Record organizes recordings in subfolders in your iCloud account, which means you can view the contents of each folder (presumably containing renamed files) with a stronger press in the app.
I've been using Just Press Record regularly on my iPhone for the past two months, and I've recommended it to friends who also find it superior to the default Voice Memos app. Version 1.2 is available on the App Store.
