best baby monitor?

TtcMommyof1 • Wife to a wonderful man ❤️. Mommy to an amazing 6 year old girl 💕. Due 11/8 with a baby boy after 37m ttc💙
Looking for a video monitor with a good distance range (nursery will be on second floor while master bedroom is on first) to use once baby leaves our room. Would love if it had an app so we could watch from our phones also, but I've read iffy reviews on wifi monitors, and our internet isn't the most reliable 🙄. Any suggestions?
