I have no idea why it's not more well known in the Jewish world.
Well I went on their website and the creators of the accountability2you are christians. They start their mission statement by saying how the creator is a believer in jc and they of course foolishly claim as if that nonsense is the word of Hashem when in fact it's the words of a few jews who wanted to take the yoke of heaven off of themselves. See here for if want to find out more of why I'm disgusted by the obvious shecker of this nonsense:
Jews for Judaism
And its nothing personally against them in particular, although they did steal our Torah and filled it with mistranslations and now arrogantly claim jews are in the dark of the truth on top of all the times they censored the words of the sages (most hilariously tractate avodah zara from the talmud) and even on top of all the times these people censored their own false testament from their fellow idol worshippers by keeping it in a language only the priests can understand (and I know most of this is from my education in a secular high school in America). The same stands true for all the false religions of the goyim whom aren't observant bnei-noach (like islam also). But here's why I can see why it's not popular in the jewish world and I personally wouldn't want to get just for that.
Please don't take this personally though, from what you and others say I would hope there's software similar to this from other sources that aren't associated with people like this. I just can't stand people like that whether they're non-jews or jews.
