Chronofile

Chronofile is a personal time tracking app. All data is saved to a chronofile.tsv file on your device. This app is 100% offline and never accesses the internet - no ads, no telemetry, nothing. - Source code: https://github.com/artnc/chronofile/ - Blog post: https://chaidarun.com/ten-years-of-logging-my-life - Hacker News comments: https://news.ycombinator.com/item?id=29692087
