Help Me ID this app - Is this snapchat?

My girlfriend's been acting sus lately, and I suspect she might be cheating. I'm too scared to snoop through her phone, but her friend posted a story today showing her using an app that doesn't look familiar to me. Is anyone able to identify the app from this blurry image? It does look like snapchat but chats should have a bitmoji instead of that placeholder. I know I should talk to her directly, but I'm worried about starting a fight if it turns out to be nothing
