Pivo uses the phone's internal storage. Depending on your smartphone model and the internal storage capacity, the maximum length you can record varies.
iOS users can record a video as long as the phone storage can save them. While Android users can record up to 4GB files each time due to Android's restriction. Please note that the length of the video can differ depending on the resolution used, the higher the resolution the faster it reaches the 4GB limitation.
