The opening roll

Picture this: you’re sitting at a coffee table somewhere, smack dab in the middle of an intense, whoever-blinks-first showdown of a game night.

Maybe you’re surrounded by a group of friends. Maybe you’re amongst family. Either way, they’re all opponents now. You open your phone, tap an app for a quick dice roll, and await your fate.

That kind of a no-fuss-no-muss quality is exactly why an app like Dice Roll SNS succeeds: people just want to roll, and move on.

As Sergey Senyuk puts it, the app resonates because it’s “simple, fast, reliable, easy to use during tabletop, board and dice games.”

It’s also become the signature trademark of indie developer Sergey Senyuk, namesake founder of the app business Senyuk, who after years of freelancing and contracting for other companies, decided in 2019 to start making apps of his own, each beholden to a singular design philosophy: make things that are useful, but make them clean.

That posture is a rather deceptively simple one when you think about it. It means that someone just like Sergey has to dedicate a significant amount of time and thought to what exactly gets left on the cutting room floor.

And when you look across all of Sergey’s other titles, they sort of fall neatly into line. Radio Explorer SNS offers straightforward listening. Sudoku SNS gives you clutter-free puzzles. And Candle Light Relaxation delivers clean, minimalist tranquility.

“My mission is to build simple, free-to-use, useful apps with a clean UI,” he says.

Even their names bear another one of Sergey’s trademarks, many of them stamped with his initials “SNS.” That, in a way, makes sense because, the way Sergey tells it, he was simply setting out to make something he himself would use, and that he personally would find useful. “That has been the driving force behind all my apps.”

But in building for himself, Senyuk has managed to also help people from all walks of life. Casual Android users looking for a quick tool. Tabletop gamers needing a dice app. Some want calming audio. Others are rather niche — gymnasts and coaches that use his Gymnastics Judging Symbols app, for instance.

Dice Roll SNS has become Sergey Senyuk’s flagship app, built for quick and reliable dice rolls.
Playing the long game with ads

To that user opening up Dice Roll SNS during a game, the experience is seamless: the app is there, it works, it’s free.

But for Sergey, keeping it that way required making one more big design choice. Rather than throwing up a paywall or charging a subscription for his apps, Sergey went with an ad-supported business model instead, and by doing so, has been able to keep his apps free and accessible to users all over the world, across different countries and markets.

And for Senyuk, advertising has been central to the business ever since. In fact, Sergey reports that 95% of his revenue comes from ads these days, revenue that’s given Sergey a way to keep his apps broadly available, while still turning them into a real business.

A user gets a free app for game night; Sergey gets to keep maintaining and growing the business behind it.

Sergey also mentioned that he chose Google AdMob for his ad provider because of its diverse ad format options, detailed reporting and analytics, and stronger brand-safety controls, especially compared to other options he’s considered.

For a solo publisher like himself, that feature set really matters: yes, good monetization is important, but the tools also need to be manageable, they need to stay trustworthy, and not at odds with the experience his users came for.

That’s also where AI has started to play a small but meaningful role in Sergey’s process, by helping him make sense of data faster. Case in point, Sergey leans on AI now to help him analyze all his AdMob data and reporting, especially for identifying trends on “what’s performing well, and what’s not.”

“Sergey went with an ad-supported business model instead, and by doing so, has been able to keep his apps free and accessible to users all over the world, across different countries and markets.”
What the next move has in store

At the moment, Senyuk still counts itself as a one-person business, with Sergey handling everything himself: development, design, support, and marketing.

One benefit from this structure, though, is how the feedback cycle between user and publisher has remained an unusually tight one. As a matter of fact, Sergey reads and replies to each and every review himself, and, if that weren’t enough, he regularly ships updates that include the most requested improvements and features.

“The most rewarding part is when users thank me for a requested feature or fix after I’ve implemented it,” he says.

Senyuk has changed Sergey’s life too. Running the business has given him what most freelancers, past and present, spend years chasing, and that’s freedom: the freedom to work how he wants, to take time off when he wants, and to work on ideas that actually interest him.

Meanwhile, Sergey is still building, working on one thing at a time. His latest focus: a weight-loss management app called Hunger Mind that he’s recently launched. Beyond that, he plans to keep moving through new ideas as they come.

But the simple, dependable formula behind the apps will always remain the same: build something useful, keep it free with ads, listen carefully, improve it… and roll again.
