Comments on Calculator Vault With Backup for Android

★★★★★ best app
★★★★★ This app is very good n helpful cos it enables the user to some pictures secretly........
★★★★★ Very nice and good app
★★★★★ you've done a great job updating the application 👍
★★☆☆☆ There is problem occurred in this app. I have put my code in this app but your app disappeared I have done this process again and again but nothing. Pl help me in this regard as my too much data exists in this app.
★★☆☆☆ i had this app for roughly two years or so. for the first year, the app worked fine until one day a video i had on here wouldnt play. i tried to play other videos but what ever the problem was it wasnt going to be easy to fix. this lead to over a month of trying to watch youtube but not being able to due to an error caused by something unknown. it stopped when i deleted this app. this app is pretty much malware and it nearly bricked my phone. i suggest finding something different to use.
★★☆☆☆ App no longer works since last update. Crashes upon attempting to open. Data and files stored bo longer accesable. This seems to be a common theme with this app's updates that will cripple it and make it unusable to some degree.
