Currently working on expanding TheLifeSigns service
Living solo is great. But there is a chance that someone gets incapacitated and can not call for help. TheLifeSigns service sends a daily email with a lifesign button. In case you are not able to press the button, TheLifeSigns automatically sends requests to your buddies to check in on you. This can be life saving.
Comments on the site and suggestions on how to grow it outside the Netherlands are very welcome.
