This is the first in a new series of weekly app recommendations, where I’ll highlight something I’ve been using for years or recently discovered and believe is worth showcasing. Some of these apps will have a big impact — like my favorite email service, Superhuman; my preferred search engine, Kagi; or Vivaldi, the browser that should be more popular than Chrome. Others will be smaller tools, such as a way to download any video online or the best calculator app available.
