## Featured reviews

- **2★ · March 9, 2021** — It does the job well but it's a minefield of ads. I don't mean a few ads, I mean if you press the wrong button (which is easy to do), you've opened an ad up. The pay version is too expensive to purchase so you're left with this nightmare of ads to navigate. I would try another app but this one does work the best. You say you removed the ads from my account. How? I just opened the app and it's an avalanche of ads! I understand that you need to generate money but this is ridiculous
- **3★ · November 27, 2018** — This was my go to app until they forced a feature where I would swipe from one of the bottom corners that had shortcuts for quick settings and was forced to show ads. So there was an ad no matter where I was, home screen, settings, any app. I couldn't find an option to turn it off in the vault settings. I hope you guys stop trying to expand on where you are not needed. I downloaded this for a secure media vault, nothing else.
- **1★ · June 7, 2023** — This app auto deleted all my videos that I saved over the course of two years, approximately 100 videos...just gone! There is no customer service option to even try to troubleshoot the issue. These were irreplaceable videos! I am just left with nothing, all the memories lost. I would not recommend this app at all. PS Latest update doesn't eve open app. It just crashes.
