Lynx. Yes lynx. Via the terminal app of your choice. If you setup tmux to use attach then your terminal looks just as you left it when you connect. Mobile terminal apps on iOS and Android allow pinch and zoom to set terminal font size. Both OS's present you with arrow / ctrl / alt / esc keys. Phlogging on mobile is just like phlogging on PC. Most of my phlog was written on a mobile device, at least four of them, Android and iOS (in fact, I am typing this entry on an iPad via termius, ssh'd into RPoD, ssh'd into SDF). I surf on my Samsung phone via lynx exclusively. When not ssh'd into whatever, I use lynx native on my phone (I have arch installed as a chroot). Much less data usage, and no bullshit javascript ad bling extravaganza.
