[NEW TOOL] RangerPro: range editor + LeakFinder + quizzes for beginner MTT /looking 4 feedback

Hey 2+2,

I am solo dev and I wanted to introduce RangerPro (rangerpro.fr), a tool I'm building for beginner MTT 6-max players. Main goal of this post is to gather feedback: does the product resonate, what's missing, what's off. There's a promo code at the end of the post if you want to try it for free. Here are the 4 modules:

1. Ranges at every stack depth

- 1,300+ preflop ranges preloaded for MTT 6-max and Trident 3-max
- 6 positions (UTG, HJ, CO, BTN, SB, BB) × 14 stack depths (from 10bb to 100bb, every increment between 10 and 20bb, then 25 / 50 / 100bb)
- All standard scenarios: opens, vs open, vs 3bet, vs 4bet, vs allin, vs SB limp, vs BB limp-raise
- 13×13 visual editor with drag-paint, mixed frequencies (raise 75% / call 25%, etc.) and modifiers to build and save your own ranges

2. Preflop quiz

Preflop mode: the app pulls a random spot (position / scenario / depth), you click the action, instant feedback with the recommended range and correct frequency if mixed
Postflop mode: currently in development

3. LeakFinder: automatic preflop leak detection

You upload a Winamax hand history (.txt or .log) and 9 specialised detectors run through it:

- opens out of range, missed opens
- 3bets out of range, missed 3bets
- over-folding vs 3bet
- 4bets out of range, 4bet calls out of range
- open calls out of range, 3bet calls out of range

Each leak is ranked by severity and linked to the source range for that spot + an animated replayer of the hand. You see exactly where, against whom, and with what you deviated. 50 analyses/month on Pro.

4. KO / SKO Token calculator
For PKO/SKO players: the calculator converts the value of a bounty token into BB, euros and chips at any blind level.

Very useful for adjusting your shove/call ranges when you cover a short stack and dead money changes everything
