What is the best "Spy tool" ?

[Kekeli]

Hi everyone,
i'm a beginner in this space and i'm caught up in the information overwhelm disease.
I realized that a lot of affiliates recommend "Adplexity" for spying but i noticed there are different versions for Adplexity;

• AdPlexity Mobile
• AdPlexity Adult
• AdPlexity Native
• AdPlexity Desktop
• AdPlexity eCommerce

Now, as a beginner with a small budget i don't know which version to start with since i cant afford all now ( i'm looking at promoting gaming offers on Peerfly).

Here is the structure i want to follow;
1. Traffic source;
I want to start with Popads
2. Tracker;
i want to start with Testeasily
3. Spy tool;
Adplexity

So my dilemma is, which version of the Adplexity should i start with?

I want to start with the Gaming Offers because it's largely recommended for beginners-(i don't know if you guys think other wise though).
