Another feature you can interact with on Retroplay in regards to TikTok is voting for other TikTok creators or their videos. To do this, you do have to link your Google or Apple account to the app. Then, you can vote for your favorite TikTokers or videos. There are multiple categories in which you can vote for different creators, so you can give credit where credit is due after a year of watching TikTok videos for hours at a time.
