What paid software or subscription did you replace?

A developer replaced a paid iOS weight tracking app called Trendcurve with their own version, built with the help of Claude. The original app smoothed out daily fluctuations and showed actual trends, but the developer desired additional features and proper German localization. Their custom-built app is now available on the App Store, prompting others to share what paid software or subscriptions they have replaced.

This report highlights a specific instance where Claude's assistance enabled a developer to replace a paid app with a custom solution, unlike general discussions about AI's impact on development.
