I like tools that doesn’t require internet to work;

Most of the mobile applications now have some offline-viewing mode; To make the app really offline-first, it needs to be able to also create content without having Internet connection.

Offline-first tools I use

  • Managing tasks:
    • I use Trello + Unito + GitHub issues to manage all my todo-lists
    • Details
    • Trello as the offline-first application to view and manage my todo-lists
    • as a system that will synchronize my changes on Trello with other tools as GitHub Issues
  • Bookmarking & Reading:
    • Pocket
    • Kindle
  • Managing code:
    • Git is offline-first natively
    • To improve the chances of not being locked, it’s easy to develop a script that will fetch every cloned repos locally
    • Something like: for git in $(find . -name .git); do (cd $git/..; git fetch -a) &; done
  • Taking notes:
    • Apple Notes is magic but I try to leave it as it only works on Apple devices
    • Google Drive supports creating text, presentations, and spreedsheets
    • I’m still looking for a cool tool to create diagrams, especially on my phone

Offline-first for developers

  • CRDT
  • IPFS
  • Bluetooth Mesh Networking
  • Sidechain/Offchain related things on blockchains
