Without realising it, you probably perform certain actions in certain circumstances, such as when you get to work, when you return home, when the battery level falls below a certain level, and so on. Trigger for Android automates those actions.
For example, when you arrive at work, you might put your phone into silent mode to prevent friends from calling you or unwanted beeps and chimes with new social media messages. You may keep the Wi-Fi off when you are out, but switch it back on when you get home. You might use Bluetooth when you get into the car in order to play music or use a hands-free mode, and so on.
It is not a big deal performing these tasks and they are usually easy to do, but why do them at all when you can set up your Android phone to perform these tasks automatically? That is the idea that Trigger is based on and the app can be configured to perform all these tasks and more automatically without you having to do anything.
It is called Trigger because you define a trigger, which is a condition that tells the app to perform a task. The free version of Trigger has a limited number of triggers, but the Pro version has a lot more and this makes it much more useful.
To test the app I set up a simple trigger. When I am out with the phone it is hard to see the screen and they don’t work well outdoors or in strong sunlight. The automatic screen brightness option on the phone, a Samsung Galaxy S4, is just too dim, so I prefer to set the screen brightness manually. I drag it to the maximum when I leave home and when I return I have to manually reduce the brightness because it is eye-wateringly bright indoors.
Trigger can do this automatically. What you do is to create two triggers. One is activated when the phone disconnects from my home Wi-Fi (when I leave home) and the other is when the phone connects to it (when I return home). The action performed is to adjust the brightness of the screen to a specific setting - 25 at home and 80 when I go out.
Now when I leave home and return the phone's screen brightness is set appropriately and I do not need to adjust it. It is really useful, it saves time, and I don’t need to remember to do this task myself.
The triggers in the free version include Wi-Fi, Bluetooth and NFC (you can buy NFC tags and place them in locations and use them as triggers). Upgrade to the Pro version and triggers can also be set when the battery reaches a certain charge level, tasks can be run at scheduled times, when the phone is charging, when a headset is connected, and more.
Restrictions can be added and triggers can be acted upon only on the days of the week you specify, or between certain times. The actions that can be performed are organised into categories and the names are fairly descriptive – wireless and network (on/off), Bluetooth (on/off), sounds and volume (set levels), display (set levels), social media (check in, tweet), messages (send email or text), travel (navigation), alarms, and more.
Trigger is a useful app for performing various tasks, but to get the most out of it you will need to upgrade to Pro, which is reasonably priced. Even in free mode however, it is still quite useful and it is well worth exploring. There are extra modules available that extend the capabilities of the app and extra functions are promised in updates coming soon.
Grab a copy and try setting up some triggers. It is surprising how useful they can be.
