Title says it. Are there any Android app or website (through Windows notification or Android notification) that notifies you when the mempool is under 300MB or when for example the medium priority is under 100 sats/vB? I hate to always check that mempool website so often just to see fees are still high. I've been checking manually for 2 weeks. I just want an app or site notification tell me 'fees are low, go on…'

By the way, mempool website is very beginner friendly and visually friendly.
