Play two videos simultaneously on your iPhone or iPad. Reviewing your own movements on video is one of the most effective ways to improve at sports — but the real breakthroughs come when you can compare your form side-by-side with a reference video. PairView was built exactly for that. After searching and finding no app that fit this need as of April 2026, that’s why PairView was created. You can import up to 3 videos for free. Unlock unlimited imports with a one-time in-app purchase.
