About

iSober

Read full description

The iSober app is a cutting-edge breathalyser management tool for daily capturing, sharing, tracking and storage of breathalyser test results for personal users, security personnel, health and safety officers and fleet managers. Users can test themselves for the purpose of understanding their breath alcohol concentration and to find out if they are below or above the legal limit in any particular geographic location. Results can be shared instantly. iSober can be used in guest mode or by sign in using your Google or Apple account to save the last 20 test results in the app. Upgrade to Pro to save unlimited test results, enable the export of results and other premium features. Enterprise paid premium users who conduct daily, random or mandatory breathalyser tests on drivers, employees or contractors are able to utilise the iSober app and website cloud service to obtain definitive breath alcohol test results that enables operators to prevent drink drivers from operating vehicles, to prevent intoxicated employees entering the workplace and to gather substantive evidence for disciplinary action. iSober for iOS supports the iSoberS Pro, AL8800BT and the iBlow10Pro (iBlow10D) breathalysers. FEATURES: • Date and time recorded with each test. • Photograph of the person tested together with alcohol test result. • Precise GPS Location and address recorded with each test result. • Last calibration date indicated in App and in the Cloud Portal. • Unique serial number traceability for each test conducted. • Multi-device user access. HEALTH APP INTEGRATION: If you would like to save your breath alcohol measurements to HealthKit (this is completely optional), then iSober can also save your measurements to HealthKit where you can view them using iOS's built-in Health app. ----- Payment will be charged to your iTunes account upon confirmation of purchase.
