GfK Radiometer

Downloaded after completing a survey. Battery heavy with no real indication as to its purpose. Also good to know that it uses your data but you can set it to wifi only. I have no confidence I will receive an incentive as promised by MySurveys so uninstalling.

Installed as part of a survey. Survey says i never installed the app, and all app does is cause my phone to crash constantly. Complete scam to collect personal data.

Only installed it as part of a survey. It runs in the background, is always on but is a big battery drain.

Drains battery dead every day access's your video camera. worst of all its been a month and they never paid me. dont install!

Ok eventually got my rewards. (About 7 weeks after said end date, beforehand it said 2weeks but after asking the survey site i was referred by they said 6-8) Never got email telling me i could uninstall. Dont know what ppl going on about heavy battery use lol. You can change preferences to use wifi only.

Not a good feeling with this one

Absolutely useless. Nothing happens. Empty promises.

The app runs longer than needed and drains your battery. You don't get paid either.

FORGET IT, THEY DONT EVEN PAY YOU TO USE THE APP.

Others mentioned audio problems, none found. Battery consumption is average for an on the fly program. Will uninstall as soon as I receive my incentive (or in 7 days, whichever comes first). Have no clue as to the purpose of this app.

I could not down load the app to my phone!!!

If an app I'm using is playing audio, it will eventually become muted when the GfK Radiometer is active. Apps only unmute themselves if I re-open them, or if I launch YouTube. Even the stock Clock app is affected, yes, it muted my alarm this morning. It also prevents microphone access, very annoying as I am normally a heavy user of Google Voice Search and voice typing as a matter of convenience. (Android 4.4.4 Nexus 5)
