May slow down phone? – Instant: The Polaroid Instant Camera Review

After purchasing this app I get a prompt telling me that it may slow down my phone because developers need to update it. I have an iPhone 7s and seems that some older apps say this after download. Please update for newer phones. I give it 3 stars for just purchasing an app that may or may not work properly because it hasn't been updated for newer phones.
