Never fully works…

Sync has a great mission statement. And the idea that all data is handled securely plus the share features are all very cool. However, the platform continues to be glitchy at times. And somehow always in critical moments when I need to look at a file on my cellphone and it won’t “sync”. Or when I want to upload a file from my cellphone and it also won’t sync.

Seamless photo sync

Easily connect to my phone’s photo app and upload images. The web app’s uploading experience is a lot more painful. I’m migrating from google drive and uploading large number of files has been a pain. The error message was confusing. The number of files to include each upload (so that it doesn’t error out) seems arbitrary and a lot lower than the FAQ said the web app could handle.

Issues with vault

Wanted to support a Canadian business but there are tons of issues with listening to audio files via vault. Sometimes it doesn’t even play, and you can’t listen while the app is minimized. Not worth your money until they make it usable.

Great overall

…. but I get the impression that whoever wrote the audio player decided to add a (non) feature to change the brightness at a swipe did this to show off rather than provide any benefit to the user. The ‘black screen’ feature is useless! Even the volume control swipe is annoying. Doesn’t replicate any gesture a user is used to.
