There are two outcomes.
1) Hard rejected.
The reviewer thinks the item is too far off the standard to warrant feedback or that it would not be productive to provide.
2) Soft rejected.
This is when an item is closer to the standard and there is something specific which needs addressing. In this case, you would get feedback.
If you get hard rejected then you cannot re-submit the item as it is. If you make significant changes (to the point it could be considered almost an entirely new item) then you can resubmit it. Basic tweaks and updates won’t be enough.
Your item is ok but it’s too basic for here.
there are many others like it
your demo is quite bland i.e. just lists out the features. COnsider alternative colours, layouts, example dashboards
there are some fundamental design flaws in your UI e.g. top-performing elements don’t look great with those shadows and quite spaced apart, ‘congratulations mike’ box is far too much empty space, generally typography could be better
