KTool - Building A $1K MRR Kindle Productivity Tool To Limit Screen Times

Kindle Productivity and Content Management Tool

Summary
Daniel Nguyen founded KTool, a tool allowing Kindle users to send news articles, newsletters, and RSS feeds to their Kindle, bundling content into a daily magazine format. KTool was developed to reduce screen time and provide a convenient reading experience on Kindle. The idea originated from Nguyen's personal concern for his eye health and the limitations he encountered with existing Kindle-related products. KTool achieved $1K in monthly recurring revenue (MRR) and was initially promoted through building in public on Twitter.
