There isn’t a dedicated “TikTok Kids,” but you can lock down the regular app with TikTok’s Family Pairing (screen-time limits + content filters). On iOS I’d lean on Screen Time’s Downtime schedules, App Limits and Content & Privacy Restrictions to whitelist only age-appropriate apps and block mature content—Apple’s reliability and privacy make that super straightforward. If you want something more curated, YouTube Kids or Messenger Kids both offer strong parental controls and vetted videos. Android can be more fragmented when it comes to timely security updates and unified screen-time tools, so you’d end up juggling multiple third-party apps to get the same level of control.
