What it does
Libra records weight and other body metrics with text notes, detailed entry history and trend views. The official page offers an ad-supported Free plan and Pro access with additional chart sharing, an API and ad removal.
The detailed history is useful when a chart prompts a question about the original entry. You can review recorded values and notes rather than relying only on a smoothed line. The product also supports several body metrics within the same record.
Sharing is a separate decision from personal tracking. Free access includes limited sharing, while Pro lists unlimited chart sharing and API access. Decide whether another person actually needs to see the record before enabling that part of the workflow. The tool visualizes information you enter; its chart is a different view of those measurements.
Strengths
- Entry history and notes retain context behind the trend chart.
- Free and Pro access make the sharing distinction explicit.
Watch out for
- Unlimited chart sharing and API access require Pro.
Best for
- Keeping measurement history and choosing how much of it to share.
