Solid

Tried several others. Easy to use, smooth flow, stable, reasonably priced. Solid.

Overall, great

Doesn’t what you’d expect. A nice multi platform option to share notes. Highly recommend.

Great App!

Love this app for the privacy and cross platform ability!

Secure and and well-designed.

Beats every secure note app I ever tried. Easy to use for one’s private thoughts and ideas, out of reach of a steadily more intrusive Government. Europe takes privacy seriously - unlike the “Land of the Free”.

Security behind a pay wall

Such a shame. Devs have put security features behind a pay wall. And a very expensive tier as well (app lock). Just too expensive for basic notes.
