A calculator webapp without ads.

Adless Calc(ulator)

Tired of cheesy ipad apps with ads? Me, too.

Too cheap or principled to pay Apple for the privelege of letting them judge your app worthy? Me, too. (Cheap, that is.)

A beautiful solution: web-app's on the home screen! An educational experiment as well.

TODO

  • replicate ability of calculator to repeat computation by pressing =
  • shiny keys
  • Add buttons in landscape mode
  • memory indicator
  • display/clear error conditions
  • Better version indication (dedicated button? info panel?)
  • Sync version in app/manifest? (read/parse manifest via js)
  • icon
  • better perf: hit keys rapidly
  • Alert user of process to save webapp on home screen if not window.navigator.standalone: http://cubiq.org/add-to-home-screen
  • keyboard input (use form text field for display instead of simple div? catch operation keys?)
  • test, deal with floating point precision problems (return 1 instead of 0.9999...)
