A few thoughts:<p>It&#x27;s hard to envision meeting every applicant&#x27;s needs with a single webapp. Excel and such may have a lack of depth to them, but at least it&#x27;s easy to add any kind of data you need anywhere. Can you think of everything that any type of applicant might want, and put it all in there without also making it overwhelmingly complex to use?<p>The financial pressures on something like this could become awkward. Your target audience is applicants, but not many of them are going to be willing to spend money on something like that. But hiring companies are also going to be very interested in this, especially if you&#x27;re doing any kind of tracking across multiple applicants over longer periods of time. And they are willing to spend quite a lot of money on the recruiting process. If you get much traction, you may find yourself in a situation where you&#x27;re making peanuts off of ads or something, not even compensating your hosting costs or personal development time, while multiple huge companies are offering you big bucks if only you&#x27;ll do a couple of things the way they want.
