Tell us more things you'd like to see the app/service do. I'm willing to try to iteratively build this out, it would start off very bare bones and eventually hopefully be something really cool. In the beginning I'd envision it as something that just reminds you there is a meet tomorrow and as you build on the skeleton it would become reminder-by-event and depending on how hard the information is to get, it could highlight which athletes are featured in the race, where you can view the event, etc.
Give me a list of features and assign a priority 1 to 5 (1 = most important)
I can only promise to try. There are roadblocks (bulk notification requires a business license, which costs $). The technical side to get notifications going is simple. Gathering the information about meet schedules is labor intensive, likely to be inaccurate, and something that must be done constantly. Regardless of who creates this, if you want it to survive in the long run, it would have to be by subscription or someone will eventually get tired of doing the work for free. I'm willing to try since I'm looking to apply things I've learned, which will help me for other business I am trying to generate.
