This Android app does those things (no foto). Its totally free, no registrations and ads free.
there is an Android app which uses Flic as panic button. Try to find "ICE & SOS watchdog". It has also lot of other functions for emergency situations.
I have done that kind of Android app, find from Play Store "SOS ICE watchdog", its free and has lot of functions.
- use Flic to start alarm sequence to max three friends (SMS or phone call)
also other functions for Flic (f.ex use as door switch, start alarm voice,...)
- monitoring motion of the phone, if no motion during x hours then alarm friends
- home location monitoring
- remote control
- ICE info at lock screen
