Скачать или смотреть Preflop Resources- Poker- Range-Reference

I'm reviewing the Poker-range-reference app. This is pretty basic and useless, except for a corner case. You choose a position and number of players, and it gives you a range. It gives you the option to click next so you can quickly see all the positions' ranges. The ranges are all blocky and linear heavily favoring broadway cards. They don't give you the stack depth but based on the ranges I'm guessing pretty shortstack?

Good for- Beginner. The first time you ever play poker at a casino. If you follow its ranges, It will keep you from playing trash but nothing more.

It is free. Is it worth its value? Its worth the time spent downloading the app only for the player described above.
