good but the connection to Sleep As Android just prompts me to install the app when I already have it

Developer Response

Hello Dexter, the integration with Sleep will automatically sync your sleep durations and regularity. If you now change the numbers and then tap the integration again, will the integration update the values to your data in the Sleep app? Could you please contact support@urbandroid.org and give us more details?

doesn't work won't connect to sleep app

Developer Response

Hello DJ, what exactly happens, if you link the apps? Do you see any error messages? When you allow sync, the Sleep app automatically tells LifeWatch what your regularity and average sleep duration are. What version of the Sleep app do you have at the moment? If you reset the values, and tap sync, is the data synced?

Just to confirm, the displayed time is 'remaining time', correct? At 34yrs old male, the absolute max remaining time for all possible positive factors provides the value 51, thus giving 85 at a max life expectancy. Does none of the scientific research show a path to 90+ years old? A nice add for the app: a toggle to show total life expectancy 'current age+remaining time' giving the actual year; then a margin of error, like a +/- years to account for outliers.

-3, damn it. Looks like I'm living on borrowed time. Well I'll keep at it, there are definitely some sliders I can improve. For the time being I'm just glad I'm not living in a Black Mirror episode because it really would have sucked to have entered the data and died the moment my number went negative.

Developer Response

Hello Michael, many thanks for your review :).. Well ignoring all the statistical errors in the process and all the unknown, having -3 actually means you are doing very well compared to the average peers :)..also I'm sure you can improve on the sliders as well..lots of greetings! Petr
