Filmic Pro has gotten very greedy over the years. Now they have change from one time fee to weekly fee to a year fee. Its not worth the money. I found one butter then Filmic Pro, Its called Cinema P3 Pro Camera app it only cost less then 11.00 for life time with all updates and its only one time payment and it has a lot more features then Filmic Pro. They have lost a lot of customers over there greed..
