The lite version lets you really try out the capability and design of the app before you have to pay for the full version. I love it as it goes from auto everything all the way to full manual in easy stages. Also one of the few, maybe only, app that lets you drop the resolution when you just want to record where you parked or the details of something in the shop to maybe send to a friend. Can split the auto focus and exposure points simply with a double tap (like camera+) - a mode I often use. I also prefer their auto digital zoom when in manual focus adjust to focus peaking often seen elsewhere. Another unique feature is naming & saving your own pre-sets. So once you have found your best settings for a sunset, save them for quick recall in the future. Finally not just stills but time lapse and full video. The video even has digital zoom whilst recording. Think it won’t be long till I buy the full version (lite is limited in resolution )
