Best iOS pgp solution

I never write reviews for apps but felt the need to in this case. This works great; easily better than anything else for pgp on iOS. I had previously paid for a pgp app but it was unable to verify signed messages correctly despite contacting the developer for help. Everything works properly with Tessercube. Much respect for the developers.

I’m looking for a privacy encryption communication software for a long time. The Tessercube fit my exception perfectly.
