Unless you’ve been living under a rock, you are well aware of the trending #SeinfeldTaughtMe trending right now on Twitter, the seminal NBC sitcom Seinfeld is a surprisingly good source of life hacks. In celebration of the globally trending #SeinfeldTaughtMe trending on twitter, I came up with a list of apps that are offered equally valuable life hacks.

1. WeTap: Are you thirsty after those pretzels? This app is to your rescue every time you’re in need of a water tap. The app also serves a higher purpose as by promoting access and use of public drinking fountains, WeTap improves the awareness, reducing dependence on single-use plastic, while improving public health. The WeTap app is now available for iPhone and Android coming soon.

2. Annoy-A-Teen Lite: We all know how annoying teens can be and this app is perfect for your revenge. The sounds (did I mention highly irritating) created by a compatible device, are at such high frequencies that only teens and adults who are fortunate or unfortunate enough to still have a teenager’s hearing. In the lite version, only one high pitched tone is available and only one mode is available. Other modes can be used at a low frequency, but it’s not outside the hearing range of nearly anybody. The app Requires iOS 4.0 or later and is compatible with iPhone, iPad, and iPod touch.

3. Bowel Mover Pro IBS Tracker: The app fills a primary void in tracking a key aspect of one’s health and fitness- Bowel Movements. The app has been awarded by Award by Healthline in the category of The Best Crohn’s Disease Apps. With its latest update it now also provides the Bristol Stool Chart for new users. This app is designed for both iPhone and iPad, compatible with iOS 10.0 or later in Apple devices.

4. Cry Translator: One of the greatest mysteries of this universe is clearly the reason behind a baby’s cry. This app has surprisingly found the answers for us. This award-winning program reliably analyzes and diagnoses your baby’s cry, to find out if the baby is hungry, sleepy, annoyed, stressed or bored, then recommends helpful solutions through The Cry Translator. It’s no surprise that the app is an award winner of Gold at Salon des Inventions de Genève 2010.

5. Drunk Dial NO!: How many times have you drunk dialed your ex or worse your mom? This app ensures you have a regret-free weekend (almost). Drunk Dial NO! hides a contact’s phone number(s) and email address(es) for between 1 and 48 hours with no limitations on how many contacts you can lock. The latest features even let you club all your “dangerous contacts” into a group and block them for the Friday night. You can even send yourself a message. The app is my personal biggest life hack and the reviews by thousands claim the same.
