5 stars: I'm a little surprised about the moderate feedback as it works very good for us. It started on Amazons Fire TV stick as I wanted to stream TV over WiFi. App there works really nice and on Android too, picture-in-picture is supported, performance is great and I get all important channels in HD. Note: used Zattoo only with premium or ultimate subscription features.
5 stars: Works absolutely fine. Might even consider a subscription for better resolutions. It does what it promises. After work I sit down, plug my phone in and I'm watching some TV. Yes, seems a bit of a boomer thing to do, but sometimes I just want to see a set program. Good job, Zattoo
4 stars: Very good service (using Ultimate), BUT: Dolby 5.1 setting doesn't save (!), some jitter, picture not perfectly smooth sometimes. Using Nvidia Shield. Also the app version on the Shield is older (.. 42) than the one on my Android Smartphone (.. 44) Why is that? It's both Android right?
4 stars: What's going on? I have been a paying customer for 4 years, have 800 recorded programs but now can't find them. Screen says I'm using the free version but pay 12CHF a month!
3 stars: Cannot use it on Nvidia Shield because it get disabled at every reboot (premium account in Switzerland). Also cannot be found in Google Play if you have Android in English. Stay away! I discussed the above problem with support and it is related to my Google Play account being registered in a country where Zattoo is not available...
