Please update this app! – Baby Log - Activities, Growth and Milestones Review

I used this app to record milestones for all our children, from infancy. Now, because the developer has not updated the app, I can no longer open it in IOS 11, and all that data is irretrievable. BHI Technologies needs to PLEASE create a fix so that faithful users of the app can retrieve their information about their children. What a disappointment!
