What you will find here

  • Tools grouped clearly so visitors can browse by purpose instead of guessing.
  • Direct access to practical apps, calculators, checkers, and helpers.
  • A shared visual language that can be re-themed by swapping token values instead of rewriting every component.
  • A cleaner layout that works on desktop and mobile without the old colour soup.

How the site is organised

  • Main tools are collected into one directory instead of split into artificial buckets.
  • Some links go to apps.hj.sg; some stay on hj.sg, depending on where the tool lives.
  • Specialised legacy sections remain available where they are still useful.
  • The directory can now inherit the same theme system as newer apps when you settle on a final palette.

HJ & CO LLP focuses on practical tools that solve specific problems quickly and cleanly.
