Periscope now lets create account using just phone number
Periscope is one of the fastest growing communities where you can broadcast live video to the world. Once you go live, your followers are notified and can join the stream and add comments and send you hearts in real time. Twitter had earlier acquired Periscope and users had to use twitter account to register on Periscope. With the new update, users can sign up for Periscope using the phone number. Other udpates include taking a new profile picture or uploading one from camera roll, tap on comment and click on reply to compose new message. Below is the full description and key changes for version 1.04. 
Description
Periscope lets you broadcast live video to the world. Going live will instantly notify your followers who can join, comment and send you hearts in real time. The more hearts you get, the higher they flutter on the screen.
Other features:
[+] REPLAY: When your broadcast is over, you can make it available for replay so viewers can watch later. Viewers can replay your broadcast with comments and hearts to relive the full experience. Replays currently last 24 hours. You can delete your replay at any time.
[+] PRIVATE: If you want to broadcast to specific people, press the lock icon before going live and choose who you want to invite to your broadcast.
[+] TWITTER: You can choose to share your Periscope broadcasts on Twitter by tapping the bird icon before you start broadcasting. When you go live, you’ll tweet a link so that your Twitter followers can watch on the web (or in the app)
[+] MANAGE NOTIFICATIONS: Periscope will suggest people for you to follow based on your Twitter network. You can always follow new people, or unfollow them if you don’t want to be notified when they go live. You can also adjust notification preferences in Periscope Settings (in Profile)
[+] HEARTS: Periscope keeps track of how many hearts you get from your viewers. The more hearts, the higher you get in the “Most Loved” list.
