Hey cgenuity, Great to see the simplicity, I am working on a very similar product, launched couple of days back on HN (https://send.rest). Best of luck.

But have added couple of extra features in send.rest

1) Calling external APIs ( Think : pull data from Facebook while running this task in future and post data on my API or send SMS )

2) Reports and retries ( Try 3 times or send me sms its failing )

3) Recurrence ( Call this task every Monday 9:00 pm )

4) SMS and Emails comes along with them ( Send SMS or Email , pick any service as your backend )

I guess without some extra features it will be difficult to get a market acceptance.
