Hi Guys, My app jailbreak VPN is in the app store for about 1 and half years now, It has 100k+ download. Some investor wanted to buy it with 250k recently. After that, I tried my best to keep my app at top 10 for the keyword "VPN". But I failed. The most of top 10 apps are Chinese app. My App has more server and better UI than Chinese apps. Still, I could not rank it well. How can I rank my App?
