Each reel is a 9:16 vertical walkthrough of one free WOWHOW tool or one guide from the blog — roughly thirty to sixty seconds, no narration required, built to be watched without sound. They exist because a calculator is faster to understand watched than read: you see the inputs, the result, and the edge case that usually trips people up.

Every reel is downloadable. Nothing here is gated, and none of the tools shown require an account — they run entirely in your browser, and the numbers you type never leave your device.

Tools covered most often: JSON formatter, GST calculator, income tax calculator, regex tester and the YouTube thumbnail downloader. The full set lives on the tools page.
