Comments and Reviews from users:

A Google user: “This app works exactly as stated and delivers more than you expect. I needed to find an app to lock away my Ring app, because my daughter was getting on my phone and seeing gifts and such (things she did not need to see) that I was bringing home. It worked perfect, and I was shocked to see just how many times she attempted to log into it (it also has the option to snap a photo when you enter wrong pin). It works beyond well and was exactly what I was looking for (and more!).” – 5/5 in Play Store

A Google user: “I see you raised your prices. I hate subscription apps. Edit: I understand and appreciate your need to make money. I don't need it that bad any. My phone series has built in secret folders. So the app was redundant security. I was willing to support for a nominal one time fee. Not a never ending subscription. Not a fan of ads either. Choosing to part ways. Thanks for the years.” – 2/5 in Play Store

Mona C: “I like the app- it locks the apps I don't want anyone opening. My only problem is when I'm trying to get in- I have to sit thru ads. And it's not even letting me get in- it's a black screen with a endless loading circle- so I can't even turn it off or access it. I would purchase this app- please make a paid version available. Not sure if there is an option for no ads or not, seeing as how I can't get in to see the options, due to the frozen ad screen...” – 3/5 in Play Store

Maya Farshoukh: “I've had this app for 4 months and everything was fine till recently. Every time I open my phone it asks to set the app as the default launcher, even though it's already set as such. The worst part is that it made my phone super slow; I waited 15 minutes for a Google search to load with this on my phone. Plus, there were many times that my screen just went black over and over again. Once I uninstalled this app, the phone went back to loading things at a fast pace, and I had no other problems.” – 3/5 in Play Store

A Google user: “The free version of this app has worked without fail. Only showing adverts when it is blocking a restricted app. Leaving half screen to unlocking and the other half to the advert in order to make this app free. You would otherwise not notice it's there. However recently it has started to request a rate, something it has not done in all the months I have had this app. Here is my rate, I hope this stops the pop ups.” – 4/5 in Play Store

Nalu: “Honestly this is an amazing app. It keeps my apps locked, hides pictures well, and even remembers apps that I had locked before even after having deleted it a while back. The only issue I have is when u click on an app, sont enter the password, yet can momentarily see the content of the app. Other than that, I would've given a perfect 5 star rating.” – 4/5 in Play Store

A Google user: “Conceptually, this should be a good app, but it doesn't live up to billing. 1st, contacts imported into the app 1st have to be contacts on the phone. (U can create a new contact within the app itself.) This makes no sense for a contact that's going to be hidden. 2ndly, Once a contact is in the app, u can't alter the name. Lastly, & probably the strongest reason for not purchasing this app: poor customer service. After an update the developer pushed, I LOST ALL MY CONTACTS & information on them (including all the texts exchanged w/ that contact, the times we called one another, & all the notes on that contact [think birthdays and such]). The weird thing about this data loss is that it only affected my contacts. My hidden photos & videos remained in tact. But the volume of important data lost is unimaginable. Some of these contacts (& text messages went back years). I reached out for the developer by email twice, but never got a response. I'd hoped that since I'd once been a premium member that my data might somehow be retrieved, but I hadn't kept premium because most features weren't used. You should probably buy another product!” – 2/5 in Play Store

A Google user: “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.” – 3/5 in Play Store

Comments and Reviews from users:

Sithu K.: “I like this app, especially for UI and simplicity. That's what I am looking for. But there're some drawbacks - showing pin number or knock figures when I am touching would be a security issue. I can't find a setting to hide it. I can only hide the drawing lines when I use pattern type. The new app can't be locked at once. I had to restart my phone to make it working. There is no search and sort in the app list. The app list is not sorted alphabetically so difficult to find an app to lock.” – 3/5 in Play Store

Emily Franklin: “Works great most of the time. I am fine with the banner ads and even the rare pop up ads however after the pop up ads you have to re put in the pass code and that is annoying. When I delete an app I have to put in a pass code but when it comes to deleting this app it just let's you do it. I got this app to ensure kids don't use any apps they shouldn't but when a smarter older one can just delete the app that kinda negates having it downloaded.” – 3/5 in Play Store

A Google user: “I really like this app, I liked something that other applock apps do not have and it is that you can use the lock even if the screen is horizontal. Something I would like you to correct or add is that having activated the option to take an intruder photo is also saved in the phone's Gallery so that it also works offline. Hence everything is fine for me was the best that I found.” – 4/5 in Play Store

A Google user: “This app is very handy.... when it is working! I've ran into two problems with it though that I hope can be fixed. You may need to consider that I use a Moto Z Play with the app. First, if you quickly go to a blocked app when the phone is first turned on, this gets around the app lock until it boots up a few minutes later. Secondly, the app sometimes automatically diasbles itself when there are system updates or updates to the app itself. Unless you open the app manually, it will remain disabled” – 3/5 in Play Store

zach gauthier: “Very nice app, and the only app I've ever purchased. Biggest complaints are that it's definitely pricey (I purchased lifetime). And the auto rotate of photos and videos is kinda annoying. Even with screen locked on my phone, the app still rotates. And if I rotate a picture or video in the app manually, it resets it to normal. Definitely kinda annoying. But overall great app.” – 3/5 in Play Store

andrea wynen: “I am on the fence about Keepsafe. Storing photos has been great. I am not a fan that the photos are not in order at all and I am trying to export photos just to use quick for a photo book but when I tried, it exported and disappeared. Maybe I am just not getting it so time will tell. Maybe I will change my rating later.” – 3/5 in Play Store

曾力: “I just downloaded it, but so far it has an easy to use and understand interface and walls you through step by step to set up the minimal security you want. Once you've finished setting things up initially, you can look through the app and make changes as you'd prefer. They have lots of useful options and it's all free as long as you don't mind occasional ads. I'll update after a while once I've used it a while with more info” – 5/5 in Play Store

Ty: “Does what it says although I will be glad to see if the app can respond quickly to the time frame between when you try and open a locked app or setting and with other apps you can usually spam tap the on/off switch where it counts it before it shows as a locked app/setting. If you know what I mean hopefully? But if it does not do well there then I'll be editing and most likely removing. Until then I say it's perfect 💪🏼💯✌️” – 5/5 in Play Store

Comments and Reviews from users:

Nicole Denier: “This is a great app, except for a couple of things. It causes some issues with some apps like distorting the graphics, and the app itself should be hidden or able to change it's icon and name. Other than that, it works great! It works all the time, every time, including pop up messages, and notifications. There's no back door way into your personal apps.” – 4/5 in Play Store

C Petro: “When it works, it's one of the better protection apps on the Play Store. Two big issues: 1. You have to give it permission to monitor your usage. That's not necessary when it's also given permission to interact with apps. It's also a huge vulnerability. 2. When an app is updated, it unlocks. Not sure if the update disconnects it from App Lock or if the version change reinstalls a new app in the old app's place. Regardless, my apps get unlocked on a weekly basis, so it's become unusable.” – 3/5 in Play Store

Adding any photos to the vault gives you the option to delete it from your phones album and keep it there, but revert if needed. The payed version is fantastic, it's multiple albums with the ability to recall if you delete something. **Saving gifs doesn't work anymore(the gif itself was corrupted, Sorry about that!)” – 5/5 in Play Store

Tre N: “Update: After a little back and forth to find the exact issue, the developers built an update to fix the problem. Bugs happen but this level of customer service rarely does. 👍👍 Original: If you don't plan to use the cloud save, consider this five stars. But every time it tries to retrieve the photos I had it gives me a "data/logic error while attempting to synchronize". I lost a lot of photos. I'd have deleted the app out of reasonable bitterness if I wasn't still holding out hope it'll work.” – 5/5 in Play Store

A Google user: “One small problem. If you are opening a locked app and select "Forgot Pattern", it exposes the locked app as it changes to the "Enter Pin" screen. I suppose this isn't a major issue for most people, but if you are locking an app that you would prefer not to be exposed, whomever is attempting to unlock it will be able to see what you were working on.” – 3/5 in Play Store

A Google user: “The app was pretty intuitive and easy to setup and use. The free version is useful but the advertisements were quite obtrusive. I ALMOST bought the app until I realized it could be uninstalled without a password. Just go to the app drawer and uninstall it. I thought the purpose of an app locker is to add a second layer of security to your device by preventing somebody from accessing certain (or all of your) apps. It isn't much of a security layer if an intruder can simply uninstall it. The app does auto-run when the device starts up but it does't auto-run fast enough and I was able to start locked apps upon start-up of the device.” – 2/5 in Play Store

Everything is good but just one thing.... when I turn off my network and try to open any locked app it just opens normally, no password required. I mean anyone can close the network and then can use those apps. So if you can fix this stuff everything will be perfect. I'll rate you full stars then. Please.” – 3/5 in Play Store

One that I noticed just after sending it - I likely upgraded and only now hours later the pattern lock seemed to recognize it on first time... Nah, just realized I had just enable showing pattern track - I don't understand how it would recognize it worse when disabled - that should not affect anything but line drawing, but just now i unlocked two apps in row in 1st try - usually it always takes 2, sometimes even three times required.

A Google user: “This app in function does exactly what I hoped it would do. Unfortunately, even after turning off the setting where it monitors all app usage and 'pausing' it during the day when I don't need it active, it drains my battery and slows down overall function of my phone. If there are suggestions to fix this issue, please let me know, as I was finding the app very helpful!” – 3/5 in Play Store

A Google user: “I love that this app allows you to set a time limit (ex: 30 min/day) and a time interval (ex: 9pm-7am) to block distracting apps. I've tried similar apps to this one before, but they only had a time limit. The interval feature on this app keeps me off my phone late at night, which is when I was most distracted. It also updates my screen time in the notification panel. Other reviews have mentioned that it doesn't work when you exit the app, but I haven't had this issue on my Galaxy S8.” – 5/5 in Play Store

A Google user: “Exactly what I've been looking for. Free version just locks you out of the phone for specified amount of time but the paid version (3.99) allows you to specify which apps you want to be locked out of, which is what I wanted. I dont regret paying, I think I will be using this app a lot. Really helpful for getting things done when you keep getting distracted.” – 5/5 in Play Store

A Google user: “Works great! The only feature I'd like to see is a 'lock in x minutes' quick add. I know you can do the scheduled lock but it's a bit annoying to have to change the times of start and end every time I want to have a lock start later in general as opposed to a specific block of time. So, it would be cool if there was a button to the effect of 'lock for 30 min (this part could be editable, but wouldn't need to be set every time) in 5 minutes.” – 5/5 in Play Store
