Usually good, sometimes misses it, but if it wants to do the pro upgrade ad thing (I'm sure you know what I mean) then it causes the alarm to continuously run until the screen is unlocked which in my case takes a while to put the password in which makes it super awkward. Solution: Stop showing that pro upgrade ad thing if the alarm is going off!

Nightmare ui, lots of permissions and upfront payment demand before anything. Didn't last 2 minutes installed Edit; in no way I'm paying for an app that uses free version only as a vending machine, has such an awful, useless UI and demands so much permissions for nothing. At the point you get to the actual app, you see it's not worth at all. There're better options around, I found one faster than typing this. But this is such an offensive excuse for an app that I'm compelled to make it.

It worked, but I'm only giving 2 stars. I had the sound turned down on the battery full alarm. When it alarmed it was blaring loud. I checked the volume and it was back up to 15. I am going to test this one more time. If it does it again I will leave the 2 stars. UPDATE- Still not working correctly. 1 star now. They got back with me and said they were sorry that I " might" be experiencing issues. Might? Sounds like they just don't want to take responsibility. App is now uninstalled.

My charger cord comes out easily from the phone so the Theft Alarm let's me know. Also, I have it set to go off at 50% for The Low Battery Level. I also use the Battery Temperature Warning with the Level set to 41° C so I can cool the phone down with a fan. I have it set for Unrestricted in the App Info page under Battery. There's a plethora of Notification options that become available after the first notification by the app is triggered. This is a feature rich application that works very well.

The filthy intrusive ads that have sound are completely unnecessary. I will give you five stars as soon as you remove these idiotic ads. I understand that having ads make it free but to have these loud obnoxious ads with sound is inappropriate. I like the adjustability of this app for battery percentages and different alarms and I don't mind ads as long as they don't have invasive sound. I'm on the hunt again for another app that is not so intrusive.

Good Day ! I am a user of your app, FULL BATTERY AND THEFT ALARM I just would like to ask what 'Charge Time' means in your app. Does it mean -the actual time it took to charge the phone up to 100% (meaning it should have the same value even if i charged it for a longer time)? Or -the length of time my device was plugged in? That is all, thank you. Very useful app by the way. -Vince

App does what I need it too. It alerts me when battery is charged, and when it reaches the % limit I set, it tells me with an alarm that I need to charge the battery. 11/15/21} Today the alarm feature that alerts me to stop charging when the battery level reaches 80 % charge, the level I set, it stopped notifying me. No sound or alarm emitted from the phone. I hope to find a remedy to correct this. It was a good app before this happened. I hope the developer will offer me some help.

This app incorrectly showed low battery voltage which I checked with a digital multimeter. Set it up for the free trial, but when I scanned the QR code on the back of the device it was tagged as a malicious website. Immediately cancelled the subscription and deleted the app. I downloaded another version of the app and it appears to be working so far.

This is brilliant although it's a little frustrating that I seem to need to access/open the app to make it run rather than it automatically working in the background. It would also be useful to be able to set the charge alarm to 65% (instead of only 60 or 70) as 65-67% is the exact charge point for my smartphone. Very useful! Thanks

I have been using this app for many years. After many many updates, I found that my phone could hardly charge and the battery was draining very fast! I find that this app was giving me problems. Prior to uninstalling I deleted many apps and the problem still the same. After uninstalling, I could charge at a very fast rate. Now my headache is gone!

It's just a battery alarm but with every update, the developer keeps on adding app permissions. Every time the app opens, it bugs you for location permission, storage permission, etc... It didn't require so many permissions years ago and it worked fine. I do not understand why an alarm app requires so many access to your phone. It won't allow you to access the main app until you agreed to all permissions to access you Google account, storage, location, etc... I purchased remove ads long ago.

Hello Developer, your application is so useful. However there is a problem that is not what I wanted to expect, because during alarming after my phone battery is full it keeps alarming after I unplug it. It only works with opening with the password but not unplugging which that's not I expect that, it should be "stop the alarm when it's unplug" so I hope you understand this problem right now. Thank you.

I've had this app on at least 5 different Android phones, probably more & it has always run flawlessly. I especially love to be able to leave my phone unattended while charging (anti-theft alert). After trying at least 9 other apps, this app is the only one that has both anti-theft charging & charged alert, both of which have NEVER failed, even if I haven't updated. Customer service has a very quick response time & even added my suggestion.

Would be zero stars, I give you one star because my phone didn't brick. Couldn't install without setting google payments, so no access to the free trial. This is usually a scam which relies on the fact that you will forget to cancel your subscription after the free trial period ends. This kind of app is simple in concept. I'm gonna write one and make it free on GitHub.

Scam - they say it has in app purchases. BUT when you open it for the first time it prompts to pay to use. If you don't it only displays useless information such as battery level that you already have displayed and it beeps when the battery level reaches 100%. So it's useless and not free.

Have been using it for months. Will continue to use it for years to come. One request though, please make the app in a way so that when it is unplugged the alarm stops ringing. That would make the app perfect. Thank you. Update- This app is now perfect. I asked the dev. to make the app in a way so that it stops ringing when unplugged if the phone is locked. That way it wont become a problem for others. And he did, I am soo happy. Point is, APP WORKS, DEV LISTENS TO REQUESTS! USE THE APP!

Update. Sometimes it works and the alarms sound off as they should, sometimes they don't and instead it only pushes notifications, after clicking on the notification THEN the alarm goes off, so if I miss the notification the alarm won't sound off until I see the notification and click on it to launch the app. The theft alarm sometimes it goes off only after entering my password, not before, it should be the other way around.

Works for a battery alarm with several options, but it would pop up ads with audio when the alarm went off, which got annoying. I was going to pay to remove the ads, but it wanted a subscription plan not a one time payment. Not worth it. Found another app that does all I need with good options. It has ads, but they were much less intrusive. I went and paid for it anyway because it was not subscription and it does a good job. ****Reply to developer: I said I would pay, but not a subscription.

Updated review (1 month usage): it stopped working. It no longer rings for some reason. Cancelling my subscription. Lots of notifications, but none that are useful and can't be dismissed. Mostly functional. The only issue I have is that sometimes the alarm doesn't stop after unplugging and turning off the alarm. It happens about 20% of the time. I paid for the ad free version because it's worth it if it saves my battery lifespan.

The battery drain was a real issue. If I kill the app due to either the battery drain, or the annoying ad that pops up at the end, the alarm doesn't trigger the next time. I have both "Start automatically" and "Enable automatically" checked in the Settings which are clearly not working. Also, if the app moves from the subscription based model to a reasonable one-time payment, many other users like me will probably consider purchasing it to get rid of the ads. Just a suggestion.
