OpenTara v0.1.6 (pre-release)

Pre-release.

Changes since v0.1.5

• 🎯 Editable goal date: the profile editor now has a "Goal set on" field. Progress in the goal ring is calculated from your weight on that day — so you can backdate a goal (e.g. after migrating your data to a new install) and get a correct percentage instead of 0 %.

OpenTara v0.1.5 (pre-release)

Bugfix pre-release.

Changes since v0.1.4

• 🐛 CSV import in LiveContainer: the file picker now accepts any file type, and there is a new "Import from clipboard" option (Settings → Data) that bypasses the file dialog entirely — reliable inside LiveContainer.

OpenTara v0.1.4 (pre-release)

Bugfix pre-release.

Changes since v0.1.3

• 🐛 Fixed CSV import: the file picker now accepts any file, so exported CSVs are no longer greyed out (notably inside LiveContainer). Makes moving your data between installs work reliably.

OpenTara v0.1.3 (pre-release)

Fourth pre-release — smarter trend view.

Changes since v0.1.2

• 🆕 Trend line (smoothing): the chart overlays an exponentially smoothed curve over the raw points, so daily fluctuations don't hide the real direction.
• 🆕 Period selector: 30 days (default) / 90 days / 1 year / all.
• 🆕 Weekly trend rate: shows the change per week (e.g. −0.32 kg/week) for the selected metric and period.
• 💅 Native chart legend and a tidier X axis (compact dates).

OpenTara v0.1.2 (pre-release)

Third pre-release — richer history & charts.

Changes since v0.1.1

• 🆕 Full body metrics per measurement: tap any entry in the history to see its complete body composition (fat, water, muscle, bone, visceral fat, BMR, metabolic age, protein, lean mass, body type, body score) — recomputed from the stored weight + impedance, so nothing extra needs to be saved.
• 🆕 Chart every metric over time: the diagram now has a dropdown for weight, BMI, body fat, water, muscle, bone, visceral fat, protein, BMR, metabolic age and lean mass.

OpenTara v0.1.1 (pre-release)

Second pre-release. The Xiaomi Mi Body Composition Scale 2 is now verified on real hardware ✅ (weight + impedance + full body composition confirmed).

Changes since v0.1.0

• ✅ Mi Body Composition Scale 2 verified on real hardware
• 🐛 Fixed: the "who was weighed?" prompt no longer keeps popping up — the app now respects your pre-selected profile and only auto-switches when the weight clearly matches a different person. Repeated broadcasts of one weighing are merged.
• 🐛 Fixed: switching profiles now always shows that profile's data (the body-metrics card no longer stuck on the last-weighed person).
