If using apps2SD do I need custom rec

I'm planning on using this app so I can install any game I want without worrying about my storage I have a UHS 1 class 10 card and was wondering do I need a custom recovery does it mess up the boot if the card was to fail after me switching the partitions or what ever it does

Thanks
