This app is unreliable. Very, very unreliable. I use it for many things, and it fails me at the wrong times.
Only 70% of recordings actually save. That's a huge problem. You can't have 1-2 hour long recordings just "not save". Right?! Sometimes it crashes while saving (and I have tons of free space). More often, it saves with no bookmarks (I usually add bookmarks while recording). So I lose the important times in the recording. Bookmarks are a useful feature that doesn't work reliably.
And just... Sometimes, losing a recording is devastating. And this Voice Recorder app often doesn't save at all.
Press, & hold on the app for 2 seconds. Then Follow the instructions to reset that app. Download an app call recording finder. 100% of your deleted items are not, & never deleted, they just go in a folder so you can't see, & or access it anymore. Whatever you deleted can be always be recovered. Let me know how it all work out.
