Free AppAbout Sentry
Tired of accidentally leaving your WiFi running all day and wearing down your device's battery? Tired of being home for hours and forgetting to turn on your WiFi? Sentry can help!
Sentry is a fully automated WiFi manager that only requires a simple configuration to start. It packs many features into a simple-to-use application so you don't have to waste any time on setup.
Sentry operates by cycling your WiFi. If it gets a connection or was already turned-on and connected, it remains on, otherwise, it turns the WiFi off to save battery.
Even if Sentry is activated you can still manually connect to WiFi or turn your WiFi without interrupting.
Sentry can be configured to run in any or all of three ways.
First, Sentry can be configured to run on a polling interval, e.g. 30 minutes, and check the WiFi status periodically.
Second, Sentry can set to check WiFi status every time the screen is unlocked.**
Last, Sentry can be set to run every time the phone boots up. Used in conjunction with the other two functions, this can either be used to make sure Sentry is always running or to simply check for WiFi every time the phone reboots.
Does Sentry running in the background use up my battery life? Nope! Not one bit! Sentry is actually only ever truly running when it's cycling the WiFi, which depending on the timeout you set, shouldn't be for much more than a minute, so no, it shouldn't negatively affect your battery life.
Please don't hesitate to e-mail me if you any questions or problems.
If you find this app useful, please consider buying the 99 cent adfree version. I chose not to remove or hide any features in this version because I think everyone should have the full experience and be able to try a product without spending any money on it. However, if you like the app, I'll hope you'll consider spending a buck. It really encourages me to actively maintain the app.
Permissions: Sentry requires five permissions.
1) ACCESS_WIFI_STATE: Used to check if WiFi is on/off
2) INTERNET: Used to load ads - check out Sentry Adfree!
3) CHANGE_WIFI_STATE: Used to cycle WiFi
4) RECEIVE_BOOT_COMPLETED: Used to restart Sentry on reboot
5) ACCESS_NETWORK_STATE: Used to check if WiFi is connected
6) CHANGE_NETWORK_STATE: Needed on some devices to toggle WiFi
**Note this is only when the screen is unlocked. Sentry will not cycle your WiFi is the screen is simply turned on. You can check the time, etc, without activating Sentry.

Checks less often and uses less battery than stock Android wifi search.

Pretty darn good if I do say so myself. Have had this for a good while now and haven't had a single issue with it. Checking the battery stats, I do see that the WiFi interval is consistent and connects when in range of a known hot spot.

App doesn't turn off wifi after I turn on my phone. I don't have any unlock screen or any swipe screen enabled, is that why? Or is it because I'm on jelly bean?

Seems to do something to my WiFi that forces me to actually turn off my phone to be able to connect to my home WiFi after sentry has shut down the previous connection.

Samsung Galaxy SIII When I need my connection it's shutoff & I have to reboot the each time to connect to my WiFi. Does not work well on this phone with ice cream OS.

I'm usually very picky about these types of apps, they gave to be absolutely perfect and do exactly what they have to do and it works very well.

I'm trying to love Android OS and this app helps. My battery use has improved when I'm out and moving around. No more hot phone due to wifi searching. Good work on this app!

I purchased this paid version a while ago. Today it found a upgrade. Upon upgrade it is not enabled in setting, if enable it ask for payment.

I had to write up a review, this app works great, but what makes it stand out is the updates. It's been a long time since I've seen a developer give daily updates and detail them out. It's good to know there are developers that really care about their products, even the free ones.

Author was very responsive and fixed the problem. Program is fantastic and my WiFi is active when I need it.

Sometimes makes Wifi stop working entirely until reboot, cuts off Wifi when I am connected to a hot spot already, and sometimes if I try to forcefully turn Wifi on it will go into an infinite loop of turning on and off. An interesting idea if implemented better, but in all honesty I don't really see much point. Wifi hardly uses any battery compared to Bluetooth/GPS/4G in the first place.

Never turned over wifi on the HTC, had to reboot Xoom to get wifi to work again. Great concept, perhaps a little work on compatibility is in order.

I stumbled across this while looking for another app and I was amazed at how simple but necessary it is. I've got a bit more testing to do with how it effects battery performance, but it seems to be helping so far.

Perfect way to control wifi to save battery and data. Must HAVE if you don't have unlimited data. Works as described!

This is a great idea, and AT&T offers a similar program for their users. I really wanted to like this one, since it offers a few more configuration tweaks. Unfortunately, I could not get Sentry to work on my Samsung Galaxy S2 Skyrocket running ICS. Sentry would not let me turn WiFi on at all. I had to uninstall and reboot to get my WiFI connection back.

For the size of this app it is amazing. And a great idea too this should be way more popular. :-)

have been using this app for a long time now and it does its job perfectly! there is just one thing i would like for it to be complete: preventing wifi to turn on when i've set airplane mode without needing to manually turn off Sentry!!!
