I've built a simple, but useful Alexa Skill - Find My Phone and I'm looking for a (rewarded) beta testers. It's a skill which can help you to call your lost phone from Alexa. Unlike others, it works with all countries and does not require to install additional apps.
If you are interested to become a beta tester, leave a comment below, or connect with me at voody.co. I will send you an invite.
Also, if anyone is interested to start developing Skills for Alexa, feel free to ask me anything!
