lost my App

I hadn’t been on this forum for a number of months until yesterday. Today I tried to update my profile and somehow lost my App. Tried Apple Apps but it doesn’t seem to be there any more.

Has anyone got any ideas how I reinstall it please

I rather think the app was abandoned - it seemed to have a lot of problems. I never managed to work it out so stopped using it many moons ago. I confirm there is nothing on Apple App store.

It just stopped working on my iphone months ago. I tried to get it back but couldn't find it so am back on my desk top. If nothing else it is easier to read than my iphone.
