Maxr1998

Welcome to my Website! // About Maxr1998

Hey there! I'm Max Rumpf, a 19-year old student & hobbyist Android developer acting under the pseudonyme Maxr1998. I am Recognized Developer and Contributor on xda-developers.com.
In my free-time, I create apps and mods for powerusers, like MaxLock, an applocker, or HassDroid, a client for the Home Assistant home automation platform. View a list of my projects here.
I'm also active on various other sites, check out the links below (if not blocked by your ad-block). You can contact me via Telegram, as specified below.


My stuff

Hardware & Software I use, like and can recommend:

  • Dell XPS 13 9360, i7-7560U, 16GB of RAM (powerful, extremely good-looking device, with an insanely good screen and battery life)
  • Arch Linux, on the above laptop
  • i3wm, a fast and powerful window manager once you learn it - Link to my current config
  • fish (much smarter auto-completion than bash, and a lot of cool additional features, but scripting in it is kinda weird)
  • Vim, link to my config (I never thought I'd actually use this one day. I don't even now recommend anyone to use it, if you don't want to spend more than 20 mins learning and configuring a FILE EDITOR, but damn, if you do, it's FAST)
