TangoRisto is a companion app to NHK News Easy which I believe lets you toggle the furigana on or off (it also gives you on-click lookup and the ability to study words).
You could also try something like Satori Reader - it is a paid service but a reasonable number of their articles are available to read for free, and they also let you toggle furigana.
If you check ‘free online resources’ in this post you should find a few more ideas too - oh, ‘online readers’ might also be helpful to you.
