I use a lot of SEO tools and especially tools to track keyword positions on Google. So I hesitated for a long time before taking this deal, especially because of the low number of competitors expected at the start. But now with 10 competitors for 3 tier, I think True Ranker is a good choice which looks very promising to me.

The strong points :
-Easy to understand use
-Project sharing mode (I would like the competitor and Visibility modules to be also integrated)
-Quickly add keywords via the Google Search Console
-SEO Analysis which is generated quickly
-Number of keywords per day / price
-Visibility Index
-Mobile app

Points to improve :
-Adding keyword by CSV (does not work for me)
-Very succinct SEO analysis without specific action aid
-Project creation (when adding I have a screen that gets stuck on a spinning gif, I have to reload the page)
-Graphics are quite dull
-No graphics for the competitor view

Weak points :
-Not as thorough and precise as Nozzle on the SERPS view (but it's more general public too)
-No classification by Tag or group of keywords in native (you have to go through the filters and it does not seem retroactive)
-Limited overlaps and filters

Overall the interface is clear and easy to use which makes it an ideal tool for customers especially via the share link, which is a great idea (I would like to have also the competitor and the visibility view into this share-link). The limits are generous with the 3rd tier. The team seems to be very attentive to users.
