I Built an Offline Personal Finance Tracker Using Only HTML, CSS & JavaScript

Short summary

The author built P-Tracker, an offline personal finance tracker using vanilla HTML, CSS, and JavaScript—deliberately avoiding frameworks to reduce friction for non-technical users. Developers tend to over-engineer for portfolio appeal while real users prioritize simplicity and ease of use. Shipping a practical product that real people actually use taught far more about product design than any tutorial.

  • •Built offline finance app in vanilla JS, deliberately simple for real users
  • •Developers over-engineer for portfolio/peers; users want simplicity
  • •Shipping real products teaches more about product thinking than tutorials

Generated with AI, which can make mistakes.
