Shot Tracer 5.6 update for iOS focuses on performance improvements and adds a number of productivity enhancements:
CROP REFERENCE When you add Name & Score to your video, you can now turn on square video reference lines in order to better position the pop up window for Instagram exports. This wont crop the exported video rather position the name & score pop up so that you can then manually crop it when importing a square video into Instagram.
FULL SCREEN VIDEO RECORDING The header bar was removed from the video camera in order to give a full field of view.
