你哋近期喺社交平臺睇過嘅手機應用程式廣告入面覺得最深刻嘅係邊一個英文

"You guys" is the most appropriate translation for "你哋" in English. However, if you're asking about the most memorable English-language mobile app advertisement, you would need to specify which social media platform you're referring to, as different platforms may have different ads. If you can provide more context or details about the ad, I would be able to better assist you.
