To win the grand prize, all 6 numbers on your ticket (5 plus your Powerball) must be drawn.
If you took the annual annuity payments it would be 30 payments (1 payment for 30 years) for a total of around $626 million. If you took the lump sum, that would come out to around $550 million after taxes and fees. The current Powerball jackpot is the 3rd highest ever at $1.2 Billion. However, the app is convenient as you can make quick picks, pick your own numbers, and do anything else you would want to do at an in-person lottery location all from your phone. Note there is a service fee added to lottery purchases on the Jackpocket App, making it slightly more expensive than buying them in person. You will need to set up an account and add money to it to play Powerball, as well as several other lottery games. You can also play online with the Jackpocket App, which is free to download.
