Sight reading resources

Good link from Prof. Kate Boyd: https://thepianoprof.notion.site/sightreading

Has anyone tried services like sight reading factory? I went through all of Hannah Smith's sight reading exercises in her book and it helped kickstart my reading improvement.

I also try to read old repertoire I haven't touched in a long time, and easy material I come across online. But I'm not as deliberate about my reading practice as I should be.

Any other sight reading resources our (very small, but hopefully growing) community recommends?
