TweetControl App will be discontinued on August 15, 2018 | Announcements | Forum

As an alternative, the following will recreate the functionality of TweetControl.

1) Log in to https://www.IFTTT.com
2) Log in to https://www.twitter.com
3) Go to https://ifttt.com/twitter and click the 'Connect' button and authorize IFTTT to access your Twitter account
4) On https://www.ifttt.com on the top right, click your name and select 'New Applet'
5) On the page that shows up, click '+this' and search for Twitter in the services
6) Click the 'New tweet by you with hashtag' option
7) Enter the hashtag you want to fire the ThingHTTP, for example I use '#pseudoTweetControl'
8) The click the '+that' and on the 'Choose action service' page that shows up search for 'Webhooks'
9) On the page select 'Make a web request'
10) In the URL field, paste the URL of your ThingHTTP, set the content type to 'text/plain' and click 'Finish'

Now, whenever you tweet #pseudoTweetControl your ThingHTTP will be executed. Note that rate limitations imposed by Twitter, IFTTT or the service you are interacting with using your ThingHTTP may result in success of the ThingHTTP at a different rate than your tweets.

At this point it is not clear how IFTTT will be affected by the Twitter API restrictions. You may want to keep an eye open around August 16th, when Twitter API restrictions go into effect.
