I just found another awesome Rank Tracker tool after many days (Another awesome tool was AccuRanker). Thanks goes to Appsumo & RankTracker. They did it for us. Thank you.

The most important part of this tool is: This is not only a simple Rank Tracker tool, but also a Keyword research tool. Specially I loved its Keyword Finder, SEO Checklist, & SERP Checker features. Anyone can easily find a rankable keyword with its LSI.

Pros:
- Very easy User Interface. Anyone can add domains & keywords easily.
- Unlimited Domains.
- Keyword Research such as Keyword Finder, SERP Checker features are awesome.
- On-Page Technical checking SEO Checklist is another awesome feature.
- Competitors domain adding feature is another awesome system.
- Very reasonable price according to other LTD.

Cons:
- No email notification system for the up/drop keywords.
- 100 Keywords limit is very low. And when add both of Desktop & Mobile it goes to half.

Overall, so far so good. I bought one code. But after seeing the UI & other features in the Dashboard, I immediately decided to stack maximum code.
