Life and economy simulation in your browser
In LEONIS you take a job, budget your money, invest it on a fictional exchange, move home, travel and meet friends. Wages, rent and instalments follow fixed dates and carry on while the app is closed. What you own and experience comes back later in the game.

Status: LEONIS is under active development, and the team switches some areas on step by step. Depending on settings you may need an invitation code to sign up: through a friend's invitation link or by email to support@leonis-app.com. What is new
How it works
There is no fixed path and no final level. Someone who starts frugally and builds step by step experiences LEONIS differently from someone who takes big risks early.
Create an account, choose your home town, €15,000 of starting capital in play money. An optional guided start suggests your first steps.
Take a job, for example in a café. Wages arrive on Mondays. Training and experience open up better-paid positions.
Choose your living standard, save, invest or take out a loan. Every decision has ongoing consequences: instalments, interest, running costs.
Find a home, travel, eat out, play sport, meet friends. What you experience later appears in your life story.
Preview, no sign-up needed
This is how the start really goes, shown with real captures from a test save. The order is a suggestion; apart from your account and home town nothing is required.
First
Create an account, choose your home town (the first choice is free) and receive €15,000 of starting capital in play money. An optional first chapter suggests work, daily life or the world as a direction; “Play freely” skips it.
What to watch: Your home sets tax rate, price level and local time. Moving later costs €900 of play money.
Next
Under My life › Work you see open positions and what you would earn. Better jobs require experience, passed lessons or further training.
What to watch: Wages arrive once a week, on Monday for the previous week, even when the app is closed.
Same day
In My day you plan what happens before and after work. Game time is real time: a dinner or a course lasts as long as shown.
What to watch: Overlapping plans can't be booked at once. The app tells you what clashes before you book.
On the first Monday
On Mondays your wage arrives and living costs are deducted: housing, food, transport, leisure and other, each at the level from frugal to comfortable you chose. Everything is listed under Money › History.
What to watch: Rent, loan instalments and insurance are added once you take them out. The payment calendar shows what is due when.
In the weeks after
An emergency fund of a few months' spending is a good start before you invest on the fictional Leonis exchange or buy bigger things. Life planning works out where a savings rate can lead.
What to watch: There is no second starting capital, and play money can be neither paid in nor withdrawn.
The areas of the game
Five areas form the app's navigation: Overview, My life, Money, Possessions and World. Behind them is everything that makes up a life in LEONIS.
Daily life & work
You start small, for example as a café assistant. Your wage arrives every Monday, and living costs are deducted weekly too. Stay with it and you move up four career levels, train further or change profession.
Money & decisions
With €15,000 of starting capital in play money you decide how much to spend and what to invest. On the Leonis exchange, companies, prices and news are invented. The countries carry real names; their economies, rates and events are simulated and move prices together with quarterly results.
Property & living
First renting, later owning: you buy property outright or with a mortgage. Live in it and you save on housing costs; let it and it brings in rent, along with vacancies, service charges and upkeep.
Vehicles & travel
From bicycles to motorhomes: vehicles from fictional brands have running costs and lose value. For a car you first need a driving licence. Trips lead to real countries and cities, by plane, train, coach or car.
Places, leisure & culture
From snack bars to fine dining, with menu, opening hours and price up front. A visit takes real time.
Check in, room, minibar, restaurant and spa. The hotel remembers your earlier stays.
Boutiques in world cities. You buy on site and during opening hours, with advice, made-to-measure orders and waiting lists.
Golf courses with range, lessons, 9 and 18 holes, clubhouse and membership. Plus leagues of fictional clubs with tickets.
Concerts, museums, exhibitions, sights and festivals through the year, in your city and on your travels.
Get-togethers, evening receptions and events, from boutique evenings with a dress code to garden parties.
Style & collections
Clothes, watches, art and collectibles are not decoration. They have a value that changes, and some events call for a dress code.
Contacts & friendships
Friendships start with a link or QR code. Then you plan trips and get-togethers together, from games nights and garden parties to car meets. For shared activities everyone pays their own share.
How it connects
Possessions, relationships and experiences interlock. These five examples come straight from the game's rules.
Driving licence→Further training→Car
You can only buy a car once you have passed the driving test through further training. A bicycle or e-scooter works straight away.
Own home→My home→Get-togethers at home
A games night or garden party “at home” requires a property you own and live in. You decide who may look around.
Career level→Contacts→Business meeting
You can host business meetings with a company of your own or from level 3 in your job.
Trip→Boutique on site→Life story
In the shopping district you can only buy when you are in that city. Trips and big steps later appear in your life story.
Wage on Monday→Living costs→Payment calendar
Wages, rent, instalments and living costs follow fixed dates. If your balance will not cover the next few days, “My day-to-day” warns you in advance.
Stories & memories
Short moments happen during a flight, a dinner or a concert. At the end comes a reaction that fits the booking: a long-haul flight in economy feels different from one in a private jet.
Inside the interface
Real captures from a test save with a made-up name. Swipe the gallery sideways or scroll it with the keyboard.
Devices & access
LEONIS runs in the browser. On large screens the app switches to its own desktop layout with a sidebar and two columns. Your progress lives in your account and is the same on every device.
Open in Safari › “Share” › “Add to Home Screen” › “Add”. Notifications only work this way (iOS 16.4 or later).
Open in Chrome › menu (three dots) › “Install app” or “Add to Home screen”.
In Edge or Chrome choose the install icon on the right of the address bar › “Install”.
Safari (macOS Sonoma or later): File › “Add to Dock”. Chrome or Edge: install icon in the address bar.
Note: all images are real screenshots of the app, taken in a browser (Chromium) at the respective screen size and device profile. They were not captured on the physical devices shown; the frames are schematic. Automated tests run on Chromium (Chrome, Edge), so LEONIS is best tested in Chrome and Edge. Safari and Firefox are supported but not tested automatically.
Latest
Sign-in is better protected against misuse, private profile images can only be reached by the intended people, and an account can be deleted even with open player loans. The loans are settled in the process.
You decide whether anyone may send you a friend request, can mute friends and see the status of your reports.
When an action is not possible, LEONIS explains what prevents it, what is missing and which next steps exist. Failed actions get a reference number you can give to support. Search understands intents such as “find a flat”.
Frequently asked questions
More answers sorted by topic, from account to exchange: all questions. For problems with connection, loading or bookings: Problems & support. New here? First steps and game time. Personal help by email to support@leonis-app.com.
A life and economy game: you work, budget, invest, find a home, travel and meet other players. Companies, prices and news are fictional, and only play money is used. LEONIS is not investment advice.
For anyone aged 16 or over who enjoys life, building and economy simulations and would rather use play money to find out how wages, fixed costs, loans, property and a stock exchange interact. You do not need to be online all the time: much of it carries on according to fixed dates, and a short look each day is often enough to make decisions. You need no prior knowledge of money or markets; the lessons explain the basics.
The game is free. There are no purchases with real money, and play money cannot be paid out. Google ads are only loaded after you consent.
Create an account on leonis-app.com. You must be at least 16. Depending on the team's settings, you may need an invitation code. Afterwards €15,000 of starting capital in play money is in your account, and an optional guided start helps with your first steps.
In the browser on iPhone, iPad, Android devices, Windows PCs and Macs. LEONIS is a web app: you can add it like an app via “Add to Home Screen” (iPhone, iPad) or “Install app” (Android, Chrome, Edge). There is no app in the App Store or on Google Play.
In your account on the server. You sign in on any device and carry on there. In settings you can download all your data or delete your account.
Yes. LEONIS runs in real time: wages arrive on Mondays, deductions have fixed dates, and a restaurant visit or a flight takes real time. There is no mode that pauses payments. Notifications remind you if you turn them on. On iPhone and iPad they work once LEONIS is on the home screen (iOS 16.4 or later). What happens while you are away
Yes: friends via link or QR code, groups with an invitation code, duels, leaderboards, a moderated chat, shared trips and get-togethers. For shared activities everyone pays their own share.

The idea behind LEONIS
LEONIS grows out of Fabi’s passion for games, economics and the small details that bring a world to life. His idea: a game in which you go your own way and discover what your decisions lead to.
