Spotlight: Qualcomm's Trepn Profiler app spills the beans on your chipset's workings, hunts down misbehaving apps
Qualcomm surprised us this morning by launching an Android app that wears its geek insignia with pride. It's called Trepn Profiler, and its job is profiling devices powered by Qualcomm's Snapdragon processors! But what kind of profiling is that? Well, Qualcomm designed Trepn with both casual and power users in mind. 

For starters, the information it shows you can help pinpoint apps that overwork the CPU, eat away at data, and drain your device's battery - which is great if you just installed a new messenger app or whatever, and your device has been acting up since. And if you are a developer or just love testing custom kernels, roms, and apps from the crafty bunch at XDA Developers, Trepn can help you measure performance and optimization on Snapdragon devices.

As part of its key functionality, Qualcomm's tech-enthusastic app offers real-time view of individual CPU cores' load, GPU frequency and load, network usage, and battery power in mW. This information appears on top of applications being profiled, so you can be always in the know if you have to.

When it comes to its "Advanced Mode" features, Trepn has an offline data analysis feature, which lets you save profiling data to analyze at a later time. It can also output absolute or delta battery power measurements in mW or mA units. Users can choose among 33 different data points, viewing two in a single overlay and saving them for quick access. Additionally, the data collection interval can be adjusted to lessen the load and allow for prolonged profiling sessions.

Developers can enjoy some special functionality made with app-making in mind. That is Android Intents, External control, and Per-rail power measurements. The first displays markers from your code alongside other data points to help identify power and processor spikes. The second lets you start and stop profiling from an external script or another Android application. And the third displays the power consumed by individual components such as CPU, GPU, LCD backlight, camera, storage & SD card, Wi-Fi/Bluetooth, and more.

If you feel like trying out some quality Qualcomm software, Trepn is free to download from Google Play. It does what it says on the tin and it's made by a respectable company, so there you go!

I am so happy but I don't think is coming to WP anytime soon.

Since I'm getting the Edge I won't have this app for long

The CPU profiling features in Trepn should work fine with your Edge and most other ARM processors. - Rick

I wanted everyone to know that we WILL be adding support for different languages later this year. This seems to be the #1 request and we will address it ASAP. - Rick

How many permissions does this app ask for? Qualcomm apps demand ridiculous amount of permissions.

That's a good question. Like you, I hate apps that ask for large numbers of unneeded permissions, so I insisted that we only use permissions essential to making the app work. On Google Play we have a "Permissions Explained' link that shows why we use each and every permission. I tried to include the link here, but don't have enough posts to do so. Perhaps someone else could post the link. Let me know if you have any feedback on this. - Rick

Nice to have you here, Rick! I can't hook you up with permissions, but I'll post the link you're referring to:https://developer.qualcomm.com/trepn-profiler-permissions-explained Keep up the great work!

Thanks Luis. The response to your article has been amazing. We're shocked by the number of download and reviews we've received over the past 24 hours.

Hey Luis, I wanted to let you know that we just released a new title called 'App Tune-up Kit' that evaluates any Android app in five key areas in only 60 seconds and rates it against the most popular apps in Google Play. Would love your feedback on this app. It includes a new power estimation feature that is really cool.

Qualcomm has another app called Battery Guru. I was abled to get an additional .5 days of usage after installing it. My battery which lasted 2 days in my Note 4 went up to 2.5 days before I charged. Now the app doesn't work in the Lollipop update. I hope they fix. The above app seems good too.
