Done scrolling their chats for clues? Paste their username.
LockVade app is a Snapchat lookup that pulls up their Best Friends list from a username, and never asks you to download or log in.
Free, and it runs in your browser.
The long way: wait for their phone to sit face up and unlocked, scroll their chats in a hurry, then ask and get a shrug. With LockVade app you skip all that and type their Snapchat username instead.
What opens is their Best Friends list, the people they snap, their snap score and the memories kept in My Eyes Only. The load can take a moment, and sometimes it asks for one quick step first.
