3 stars: Interface: 3/5, Comfort: 4/5. All in one app for payback applications. Understandable user friendly interface. Restricted to one language (German) is a disavantage. Limited options , so not heavy in terms of information to go through. Good app. Recommendation: Medium (if you are concerned a lot about privacy)
3 stars: It takes so long time to open the barcode. At the cashier things should be fast and lean.
4 stars: A good app for the service, but it uses high RAM, it counts as a game in some platforms and needs to improve. Please develop its security with utilizing less RAM
3 stars: keeps popping up and asks for login while I am doing something else on my phone. very annoying. also the space required is huge for this purpose and still the app often does not work when using coupons for online shopping via the app. points get lost due to this.
4 stars: I'm looking forward to the implementation / fix for the use in Android q. since I'm using Android beta this app isn't working anymore. it's constantly crashing when i try to start it.
5 stars: really nice idea to collect points with huge variety of shops, you can always gain 3 to 10 times of points with online coupons while shopping. great App !!!!
4 stars: it is good but so slow and complex. Because of this I have typed the gewinnspiel code but it has gone without something because the app has stucked.
3 stars: some crashes during Gewinnspiele, so no real chance to win. Happens in every gewin...
