OK Video is a free app available for iOS that lets users take quick videos by simply tapping and holding the screen. After taking the initial video, users can add more shots by repeating the process. Once the video is complete, it can then be sent to and shared on your different social media account, like Instagram. Designed with short videos in mind, OK Video the perfect compliment to Instagram and Snapchat stories. Without even opening those apps, you can record the video and save it for posting later instead of being limited to recording and sharing in one specific app.
