What the free tools on this site already do
The generator asks about your platform, brand, model, memory, refresh rate and finger count, then calculates General, Red Dot, 2X Scope, 4X Scope, Sniper Scope and Free Look from those answers. It is a deterministic formula: the same answers always produce the same six numbers, and nothing is uploaded or stored.
Around those numbers sit the parts that actually decide whether a set works for you: 24 written guides on testing, refresh rate, touch sampling, HUD layouts by finger count, drag headshots, per-scope tuning and troubleshooting. These public tools and guides are not gated; a subscription is not required to use them.
What a paid, manual setup can genuinely add
A formula works from your device class. A person working on one exact model can go further: check the frame rate the game really holds on that handset, watch how it behaves once it warms up, position the fire button around a specific screen size and bezel, and iterate over several sessions instead of once. That is real work, and it mainly buys you the testing time you would otherwise spend yourself.
What it cannot do is change how the game works. No paid setup gives you aim assist, faster drags than the panel can register, or a rank. If any seller claims a guaranteed headshot rate, a guaranteed rank, or values that work identically on every phone, treat that as a reason to walk away.
