Please enable true black Oled mode – Pocket: Save. Read. Grow. Review

Came from android to iOS I used to love the way this app looked and worked on Android. On iOS black is simply grey so it looks not nearly as good/wastes battery to read. Please enable true black mode!!! There can be three options if your user base seems to like grey.
