Great app but definitely needs an update – NOAA Buoy and Tide Data Review

I use this app almost daily and have for years. When it's working it's great. I'm using a 6s and it doesn't seem to be updated to function like it should. It's laggy. I frequently have to close it out and re-open. Hoping it's fixed soon or I'll be shopping around. Please update!!
