He Was 15 When He Knew Something Was Wrong. At 22 He Built the Solution.

The story of NoGree, a porn blocker and accountability app built in Port Harcourt by a self-taught developer who understood the problem from the inside.

Most people who build products identify a problem by observing it from the outside.

Jeremiah Ogbolosingha is not most people.

He identified the problem NoGree solves by living inside it. At fifteen years old, he recognized that something in his life was going wrong. His relationships were changing. His academics were suffering. His own sense of potential felt like it was slowly draining away. And the thing he could not do, despite wanting to, was stop.

He tried everything. Browser extensions. Porn blocker apps. Self-discipline. Willpower. Prayer.

Everything had the same weakness.

In four seconds, when his resolve meant nothing, he could reach into his settings and turn the porn blocker off. The very protection he needed could be removed before any accountability partner even received a notification.

"The tools that were supposed to help me were designed in a way that still put me in charge of whether they worked," Jeremiah says. "And when someone is in the middle of addiction, they cannot be trusted to be in charge of that."

That realization became NoGree.

THE BUILD

Jeremiah is a self-taught developer. No computer science degree. No bootcamp. Just a phone, YouTube, and an obsession with figuring out how things worked.

He built NoGree completely alone. No co-developer in the same city. No funding. No office. Just the conviction that the porn blocker app he needed did not exist and nobody was going to build it for him.

He taught himself Kotlin and Jetpack Compose for the Android interface. He learned VPN architecture to implement on-device DNS blocking. He studied accessibility services to build real-time on-screen text scanning. He read documentation late into the night and integrated Supabase, Firebase, and WorkManager for background processes.

Every broken build was a lesson. Every error was data.

What he was building was unlike any porn blocker available on the market.

WHY EVERY OTHER PORN BLOCKER APP FAILED

Covenant Eyes, the global market leader in content accountability, has over 1.5 million users and has existed since 2000. It works by taking periodic screenshots of your screen and sending them to an accountability partner. At seventeen dollars per month.

But it can be uninstalled on a mobile device in seconds. On iOS, this porn blocker only monitors within Safari. On Android, it relies on the user deciding not to remove it. The moment willpower collapses, the protection collapses with it.

Canopy, BlockerX, Net Nanny, DETOXIFY, and every other alternative had the same structural problem. They block or they monitor. None of them hold the line when the user decides to break it without giving the accountability partner time to react.

And none of them were built for Nigeria. None send alerts via WhatsApp. None were priced for the African market. None were built by someone who understood this problem from personal experience.

NoGree was built to be architecturally different. Not just another porn blocker. A system that does not need the user's cooperation to work.

THE THREE LAYERS

NoGree operates as a porn blocker and accountability system with three independent enforcement layers running simultaneously.

The first is a local VPN service that intercepts every DNS query on the device before it reaches the network. Blocked domains return nothing. It works without internet. It runs entirely on the device.

The second is an accessibility service that scans live on-screen text in real time across every browser and every social media app. The moment a banned keyword appears on screen, the app closes automatically. Not after the content loads. The moment it appears.

The third is tamper detection watching continuously for any attempt to disable either of the first two layers.

If anyone touches any single layer, an immediate alert fires to a designated accountability partner via WhatsApp or SMS. Before there is time to act on whatever was being attempted, the person who holds them accountable already knows.

The system does not ask the user to be honest. It removes the relevance of that honesty entirely. This is what separates NoGree from every other porn blocker app on the Android market.

WHERE RIL CAME IN

Before Renaissance Innovation Labs, Jeremiah was building in isolation.

RIL, the tech hub at 19B Ada George Road in Port Harcourt, gave him something that changed the trajectory of NoGree entirely. Not a grant. Not funding. A space.

A table to work at. A community of people who were building things. People who understood design, who knew AI, who had been through the grind of building a product and could tell him honestly what he was missing.

"Before RIL I was building alone," Jeremiah says. "You make different decisions when you are alone. You second-guess things you should not. RIL gave me access to people who treated what I was working on with the same seriousness I was treating it with."

The connections, the conversations, the whiteboard sessions, and the feedback made NoGree better in ways that are difficult to quantify but impossible to ignore.

Where a generation begins. That is what RIL says. For Jeremiah, that is not a tagline. That is what happened.

WHO NOGREE IS FOR

NoGree is built for adult men aged 18 to 35 who have already tried willpower and already tried basic porn blocker apps and understand they need external enforcement rather than more self-control.

It is built for parents who want real protection for their children. Not a porn filter that can be deleted from the home screen in thirty seconds. A lock that holds.

And it is built for faith communities across Nigeria and Africa where shame drives people away from group programs and a private, discreet porn blocker is more culturally appropriate than public disclosure.

There are over 200 million people globally whose relationship with pornography has moved beyond choice into compulsion. Children in Nigeria are being exposed to explicit content as young as eight years old.

WHERE IT IS NOW

NoGree is currently seventy-five percent complete. The MVP is active on Android.

The waitlist is open at nogree-tau.vercel.app.

If you need it, or you know someone who does, it exists now.

Jeremiah built it because he could not find it.
