Yo launched in 2014 with a concept so minimal it seemed like a joke: users could only send the word “Yo” to each other. No images, no emojis, no chat features. Yet the sheer simplicity turned it into a social experiment that captured millions of downloads. Investors poured in over a million dollars, and the media couldn’t stop talking about it. The app even inspired spin-offs like Hodor, allowing users to send only the character’s iconic line from Game of Thrones. The success of Yo proves that sometimes minimalism when pushed to the extreme becomes the very reason people pay attention.

In 2008, I Am Rich shocked the tech world with a price tag of $999.99. Users who bought the app unlocked only a glowing red gem and a short “motivational” mantra nothing else. Despite its absurdity, eight people purchased it before Apple removed it from the store. The app sparked global debate about digital value, consumer behavior, and the limits of app store oversight. It became a symbol of digital vanity: a luxury purchase meant only to show that the buyer could afford it.

Nothing delivered exactly what its name promised: a blank screen with the word “Nothing.” No buttons, no functionality, just digital emptiness. Yet the app became a viral curiosity and surpassed a million downloads. Hidden Easter eggs added to the fun entering the famous Konami Code unlocked a long looping animation of a dancing banana, while shaking the phone changed its background before displaying a sarcastic “Stop shaking, do nothing!” message. It was a playful reminder that even nonsense can become entertainment in the digital age.

iFrenchKiss stood out as one of the strangest apps ever released. It claimed to help users “improve” their kissing technique by asking them to kiss their phone screen and receive feedback. The concept was amusing but raised serious hygiene concerns, especially after studies showed that phone screens can harbor extreme amounts of bacteria. Despite the criticism, the app attracted tens of thousands of downloads before it was eventually taken down. Its brief moment of fame reflected the digital world’s fascination with bizarre experimentation.

Amid all the strange and pointless apps, RunPee actually offered value. Designed for movie lovers, the app tells users the best moments during a film to take a bathroom break without missing anything important. It even provides a summary of what happens while they’re away. The straightforward, problem-solving approach made it popular with cinema-goers around the world. RunPee proved that not every unusual app is useless some are simply solving a problem no one thought to address.
