I started a fitness tips page and the metrics inside the app are super vague. Yesterday my stretching routine reel did ok but the saves dropped and I do not know what that means for future posts. If someone here uses a detailed Instagram analytics tool that explains audience behavior, recommend it please.

Hey! So saves dropping isn't necessarily bad - it just means people watched and used your stretching routine right away but didn't need to bookmark it. Simple content often gets fewer saves than complex workout plans people want to reference later.
I had the same panic last summer when my trail safety reel got views but barely any saves. Turned out it was just straightforward info people didn't need to revisit.
For better insights beyond IG's vague metrics, I've been using viewverio.com - it actually breaks down audience behavior patterns, best posting times, what content types perform better, etc. Way more useful than the native analytics. Don't stress one dipping metric too much.
