The app has 10M+ downloads, and is already filled with ads as it is. I DO NOT want and WILL NEVER want ads as push notifications.
I'm quite sure this isn't allowed on the playstore according to the Play Console Help page. Which states:
Ads must not simulate or impersonate the user interface of any app feature, such as notifications or warning elements of an operating system. It must be clear to the user which app is serving each ad.
And shows this picture:
I now consider GPS Speedometer malware, immediate uninstall.
For simple apps like that I usually check out F-droid see if any open source versions exist. Might not be as feature rich but there's two GPS speedometer apps on there
When it comes to android apps I always look for open source stuff first. Literally just save the headache of dealing with bot-reviews, ads in app, etc.
I think this is outrageous and I fully support uninstalling this app and leaving a bad review.
However, if you really cannot go without this app, android has a very easy-to-use notification control system. Depending on the app, you may even be able to only turn off ad-notifications while keeping all the other proper notifications working. Just long-press on any notification from the app to access the settings
That app is definitely malware, be careful when donwloading stuff!
If you want an additional layer of protection I strongly suggest using a private DNS like Nextdns.io or adguard-dns.io, which are basically system-wide adblockers. Less ads and less risks to your privacy/security.
If you end up using them I strongly suggest enabling only the regional lists and the OISD list, nothing else (since too many lists could slow down your navigation and/or block stuff you need)
