About DGital Apps
DGital Apps is an independent mobile developer studio run by a hobbyist Polish developer who genuinely enjoys building small, useful tools. There is no investor pressure, no growth team, no push notifications begging you to open the app. Each project starts the same way — something the developer wanted to exist, built well, then polished until it is good enough to share with the world for free.
The philosophy is straightforward: tools should solve real problems, respect user privacy, and stay out of the way. That means no forced accounts, no mandatory logins, no data harvesting, no premium tiers that lock away basic features. Ads pay for hosting and development, and everything else is yours to use without friction. If an app does not need an internet connection, it works offline. If it does not need your personal data, it does not ask for it.
PDFinator, the web app you are currently using, is one piece of a growing catalog. It lives on the web because PDFs are most commonly handled on a desktop or laptop during school assignments, office work, or filling in forms. The mobile portfolio, on the other hand, is focused on Android — the largest, most open mobile platform worldwide — and centers on quick, everyday utilities that make small decisions easier and small group activities more fun. Read on to see the flagship of the mobile lineup.
Random-inator
Random Number Generator, Decision Maker and Tournament Manager — all in one Android app.
Get it on Google PlayWhat Random-inator Offers
Random-inator bundles everything you have ever needed a random picker for into a single, nicely designed Android app. Open it up and the first thing you see is your personal daily random number — a fresh integer between 1 and 100 generated every day. Some people use it as a lucky number, some pick a chapter of a book to read, some bet small stakes with friends on whether tomorrow's number will be higher or lower. It is a small, delightful ritual that makes opening the app feel like checking a tiny daily forecast.
Underneath the daily number sits a toolbox of six focused randomization tools, each nicknamed with the "-inator" suffix. Hasło-inator is a password generator that produces strong random passwords with configurable length and character classes. TakNie-inator is the simplest thing in the app — a big button that gives you a Yes or No verdict for any binary question you cannot decide on your own. ListaLos-inator lets you paste a list of items and picks one at random, perfect for choosing a restaurant when no one in the group wants to commit first. Eliminator goes the other direction: instead of picking a winner, it removes items one at a time until only one remains, great for knockout-style choices.
Koło-inator is a spinning wheel with customizable slices — you set the options, the wheel spins with smooth physics and a satisfying click, and whichever slice wins under the pointer is the answer. Drużyna-inator takes a list of names and automatically divides them into balanced teams, which is the kind of thing that saves at least five arguments every time a group decides to play a sport together. Every tool is one tap away from the home screen, and none of them require signing up or sending anything to a server.
Beyond one-off randomness, Random-inator has a ranking system and a full tournament module. Rankings let you track points and winning streaks across multiple sessions for any group of players — family game nights, office table tennis, board game cafes, dorm FIFA championships. The tournament module is a proper league manager: it schedules matches round by round ("Kolejka 1", "Kolejka 2"), records results, computes full standings with played, won, drawn, lost, goals for, goals against, goal difference, and points, and lets you run multiple seasons in parallel. Tabs at the bottom of the screen — Start, Gry, Turnieje, Ustawienia — keep everything organized without clutter.

Perfect For...
Schools and classrooms benefit from Random-inator more than any other environment. Teachers use it to pick students fairly when asking questions or handing out small rewards, to form random teams for group projects where no one feels picked last, and to run PE tournaments where the table updates round by round on the projector. Primary school and middle school teachers in particular love the spinning wheel, which turns any mundane selection into a little moment of suspense the entire classroom leans in for.
Parties, gatherings and family game nights are another natural home. Spin the wheel to decide who goes first in charades. Use ListaLos-inator to pick the next movie when nobody can agree. Let Eliminator slowly narrow down a list of twenty restaurants to the one place the whole group is going tonight. Set up a mini tournament bracket for a round of Mario Kart, table tennis, or backyard badminton, and let the app keep score so the evening does not devolve into arguing about who actually won the third round.
Sports enthusiasts and amateur leagues are possibly the power users. The tournament manager is built to run real competitions: FIFA leagues with six friends and twenty matches, office ping-pong seasons, board game championships, home darts tournaments. Seasons carry forward, rankings track everyone's long-term form, and nobody has to maintain a spreadsheet. The fact that it is free and offline makes it easy to bring to any venue — phone signal or not.
Families with young children use the simpler tools to take the emotion out of everyday decisions. Who picks tonight's bedtime story? Spin the wheel. Who clears the dishes? Eliminator. What is for dinner when every kid has a different idea? ListaLos-inator with the parents' shortlist. It sounds silly, but handing over the decision to a neutral phone app saves more household diplomatic incidents than most grown-ups like to admit.
Workplaces and remote teams use Random-inator to decide the order in a daily standup, to pick the next person to demo a feature at a review meeting, or to draw names for a Secret Santa exchange. The password generator is also useful for developers and IT admins who need quick strong passwords when they are away from their main password manager.
Privacy and Free Forever
Random-inator shares the same DNA as PDFinator when it comes to respecting your data. There are no accounts to create, no social logins, no email signup walls, no phone numbers, and no personally identifiable information collected. All of your tournaments, rankings, saved lists and custom wheel configurations are stored locally on your device — they never leave your phone. The app is supported by non-intrusive ads, and a single lightweight anonymous analytics event tells the developer how many people opened which screen, so the app can keep improving without invading anyone's privacy.
Free means free, forever. There is no premium tier, no "unlock full version" paywall, no trial that expires, and no feature hidden behind a subscription. Every randomization tool, the full tournament manager, rankings, history, and all future tools are included in the version you download today. If the app ever adds something genuinely large and expensive to run, it will be a one-time optional tip — never a recurring fee to keep using the things that used to work for free.
Frequently Asked Questions
Yes, the app is entirely free to download and use. It is supported by unobtrusive ads that pay for development and hosting. There is no premium tier, no paid unlock, and no recurring subscription. Every tool is available from the moment you install.
Absolutely. All tournaments, matches, results, seasons and rankings are saved locally on your device. You can close the app, come back days or weeks later, and pick up exactly where you left off. Multiple seasons can run in parallel without interfering with each other.
Random-inator uses the platform's cryptographic-grade random number generator, which is the same source your phone's security features use. For everyday picks, wheels and team splits this is more than enough randomness — the output is statistically indistinguishable from true randomness for any practical use case.
Sharing screenshots of the standings table already works out of the box. A dedicated export function — CSV and a shareable read-only link — is on the roadmap for a future update, driven largely by user requests from school teachers and amateur league organizers.
Random-inator is currently Android only. An iOS version would be welcome but requires Apple developer fees and additional maintenance that a one-person hobbyist studio cannot sustainably cover right now. If the user base grows enough to support it, an iOS port will be considered.
More from DGital Apps
Random-inator is the flagship of a growing mobile portfolio. You can view the full current catalog, plus any new apps released in the future, on the official Google Play developer page: DGital Apps on Google Play.
Several new projects are in early development — a minimalist habit tracker with no streak-shaming, a focused grocery list app that finally gets sharing right, and a lightweight local-first note-taker. All of them follow the same principles: free, private, respectful, offline-first when possible, and never gated behind accounts. If any of those sounds useful, follow the developer on Google Play to get a notification when the next app drops.
And of course, PDFinator itself is part of the same family — built by the same hands, with the same commitment to keeping your documents on your device and never asking you to sign up for anything. Explore the rest of the site using the navigation at the top of the page.
