About: ilo.so is a Twitter analytics tool that takes your understanding of your account performance to the next level. Used by lots of top profiles I've seen.
Top Features:

- A cool feature which I haven't seen many other tools do is analytics for Spaces. Awesome!
- You get daily digest emails, customizable dashboards, engagement charts, and so much more.

Pricing: Great pricing and a good incentive to go on the annual plan with 4 months free if you do (as I write this resource). Plans start from $15 per month ($10 yearly) and add more features such as Spaces (+$5 p/m) and/or Followers plan (+$10 p/m).
