I really like this app I downloaded this app few days ago and since that day I really like this app.i downloaded it first on my lenovo vibe P1 then I sold that phone now I am having mi a1 and I downloaded this app in my mi a 1 too and it works very well. There is no problem of crash or there is no problem of lagging.the idea of developers is very good and the look of the app is also impressive. I even recommend this app to my friends too and they liked it too.it worked very well on low memory phone too.i really appreciate developers move and keep making this type of apps.
