Vitals
Vitals organizes Apple Health and AutoSleep exports into daily records, charts, and sleep summaries. It keeps track of which device supplied a measurement and how daytime activity aligns with the following night’s sleep.
I built it to explore my own records over time and compare patterns across the different exports.
wxdecipher
wxdecipher is a macOS tool for organizing my WeChat archive. It works from copies of the local databases and groups messages and media for search and analysis.
Both projects run locally. The underlying health records and conversations are personal, so there is no public dataset or live dashboard to browse.
