-Lock/Unlock (Device locks if screen is on and unlocks if screen is off)


Other Options:

-Sensor Delay (set time delay before sensor detects object , useful to prevent unintentional locking/unlocking)

Nice A very handy application. Another good to have

Cool concept but has ads There should be no ads on this. This is an app I would gladly pay a few bucks for because the core concept is actually revolutionary. The ads just break the usage flow entirely. Consider a paid-only distribution model. Some apps just need to be paid experiences based on what they offer and this is one I would actually spend money on.

Filthy application Each time when I open the application it redirect me to a filthy page where girls in semi nude and ask me to buy them. waste idiotic app

Super efficient I love this. Saves me time every time I lock/unlock.

Quite useful and efficient, helping you to prevent any unwanted calls, especially when you put your phone in your pocket making it accidentally touch your body indirectly therefore dialing a number.

good but in this aap add one more function "on and off both" plz

Great app!! Works great keep up the good work.

Please add disable in landscape mode and auto start on startup. And please save user config. every change in app or closing it will reset config.

Ok my battery is doing good now. I also close some running applications on my phone which i dont wanted and switch on my proximity sensor and im happy now no problem with my battery at all. Now im giving 5 stars to this very excellent elegant proximity sensor. Good luck. I appreciate the sensitiveness of the sensor but i have to charge my battey 2 times a day.

Question Is the adware in the app a serious problem

This application is fantastic but eats lot o battery. Is it possible to stop consuming too much batter power. Because it takes so much battery, i gave 2 star. Please tell me other similar app.

Fantastic app. It is very useful app for everyone. Definitely worth downloading app.

Love this proximity app I don't need to touch phone to lock or unlock.... Great app

Great application really I recommend to use thanks

Interesting Could be useful app, but some of the permissions don't seem to be relevant (such as call info)

Really useful app.Definately worth downloading

Insightful idea Guys you just helped me a lot by developing this app..my friends will love it too

I think it is usefull app

Great app This is a fantastic app and really useful

OK but it takes lot space Its a nice app...but it takes 84 mb of ram space. Almost a launcher space..it makes my device works slower besides to that ads. pls workout to solve dis prblm

Good concept. Need more improvement.. Some times doesn't work well.

Impressive! I liked it,I hadn't seen an app use this feature before. Really impressive. I guess it probably works better if your phone doesn't have a code though, coz with a code you still have to touch the screen for it to open.

Greate app.. it adds more valuable for my device.

Nice Works but not always. Sometimes it just stuck doesnt work. But this is not often. Worth a try

Thank you for the good app which I love but I want a feature where we can rub the proximity and show a notification screen like in the one plus x . I would love to get a reply from you . ?

Amazing Just what I wanted!!

Lol it actually works. Good job !

Nice app. Make life a little easier :)

amazing app. it is very useful for everyone

Nice app Useful app, works well for me

Too much ram Good app but this app use too much ram space( about 60MB) for just lock unlock task. Please fix this. Even playstore doesn't use that much ram.

Lock/unlock It is perfect application for anybody use phones. It is easy for using to lock or unlock ur screen.

Nice work! It works very well !

Gud app but ads much more Its good now.previously it took 84mb ram space now it seems to be OK. Like your app very much. But the ads are unbearable.

Good app but seen as virus By eset security. For the ads

Love it So far i love it keep the good work :)

the ads will not let me set up

This is the best app I've managed to find that shuts off my screen when I close the cover, then wakes it up when opened. It would be 100% perfect if there was a "sleep" mode that simply turns off the screen without locking the phone, or is there already a setting for that? The settings menus and various modes don't seem to make much sense to me,

App is really good but have a problem on my phone I think. I look forward to have it fixed soon for me. Also, will be happy to buy the AD free version of this in that case.

Odd behavior Odd behavior and adds right after install.easy deinstall not possible.

Way too much ads. Don't install. Ads appear one after another, I can't even use the app because one stupid ad jumps right over the settings and options. Don't bother installing this.

Annoying ads. Ads are getting ridiculous, I can't even see half of the app!

Gr8 app I tried many of them but they stuck after sometime but it's gr8 app, it is the best app under the proximity sensor lock or unlock

only if you could club the pocket accelerometer settings with the lock/unlock feature.. would have been great!!

Ads The ads are way to intrusive

Perfect...! There are many apps like this on Google play, but this works best for me.

It's my Heart! I love it. Really it's very good app! Thanks to this app Developer!! "H"

awesome! works well with my cheap starmobile dual core...
