Desafio €0,01 Rumo aos €10.000



A 20-fortnight savings challenge with goals, tracking and a planner
Desafio €0,01 - Rumo aos €10.000 is a Portuguese-language personal finance web app built around a simple progression: start from one cent and double the target every two weeks across twenty fortnights, reaching a mathematical goal of €10.485,76. After entering a name and start date, the app generates the twenty milestones automatically. Users record what they actually managed to set aside rather than what the formula requires, then follow their progress on a dashboard and a timeline. Supporting tools include a doubling calculator, a seven-tab digital planner with printable PDF export, an expense tracker with eight categories, a per-period financial journal, achievements, a calendar and a JSON data export. Everything runs in the browser with no account, bank connection or payment inside the app.

How to Use
Create your challenge
From the landing page open the welcome screen and start the challenge. On the setup page enter a name in the field and confirm the start date, which defaults to today. The right-hand panel previews the start date, the next target and the date of the next review. Submit the form to generate twenty fortnightly milestones and land on the dashboard.
Register a saved value
On the dashboard press the register button to open the form. Choose the period from the dropdown, which lists all twenty fortnights with their target values, type the amount you actually saved and optionally add a short note. After submitting, a panel reports the target, the saved amount and the difference, and the dashboard progress and timeline update accordingly.
Explore the tools
Use the sidebar to move between sections. The journey view shows the twenty cards with completed or locked states, the calculator takes a starting value and a number of doublings and also works backwards from a desired amount, the planner groups seven tabs including a habit overview and a calendar, and the expense tracker keeps running and monthly totals by category.
Review, export and reset
Open the journal to write one reflection per period, check the achievements page to see which milestones are unlocked, and visit the profile to edit your name, export your data as JSON, read the legal pages or reset the challenge if you want to start again.
