Read full descriptionHide full description
Die BB-Level App nutzt das Bluetooth-Broadcast-Signal deiner BlueLevel oder BB-Tank Geräte, um automatisch Tankfüllstände und Libelle anzuzeigen – du musst nichts koppeln, die App „hört einfach zu“, sobald das Gerät sendet. So erhältst du sofort aktuelle Werte, und mehrere iPhones/iPads können gleichzeitig mithören und sehen denselben Status.

Verdict
The clearest difference is price: Life at Free against BB's $5.99. Life also leads on update cadence (fortnightly vs every 2 months). BB's advantage is in-app purchases (none vs 8) and iOS requirement (16.0 vs 18.0). On ads and device support there is nothing between them.
