Introduction
'How much should I bet?' That's the question BetOptimizer answers: a web application for sports betting bankroll management, with automatic optimal stake calculation at every step.
Alexandre Mallet managed his bankroll and his friends' on an Excel spreadsheet: manual stake calculations, series tracked across tabs, history impossible to analyze properly. It worked, but it was fragile, time-consuming and impossible to share cleanly. His observation: sports bettors have dozens of tools to know what to bet on, but nothing to know how much to bet. No dedicated app, no automatic calculations, no real-time tracking.
The landing page had to convince instantly. I designed an interactive earnings simulator where users enter four parameters (allowed errors, bankroll, minimum odds and number of winning bets) and get six calculated indicators on their potential earnings in real time. The design was crafted to 'blow people away' as the client put it, with smooth animations and dedicated spaces for AdSense monetization.
My approach
BetOptimizer's complexity lay in the user interface. The system handles real-time calculations across multiple simultaneous series, with complex state transitions: winning bet, losing bet, series completed, earnings reinvestment. The challenge was making it all crystal clear to the user. I opted for a system of visually distinct sliding blocks: each series lives in its own space, with a clear separation between configuration and tracking. The transition animations aren't decorative. They guide the eye and visually explain what happens when a series ends or a new bet is recorded.
Bettors don't want to do math. They want to know how much to bet, right now. BetOptimizer gives them the answer at a glance: the optimal stake is automatically calculated at every step based on their bankroll, remaining errors and odds. If they stray from the plan, an alert warns them before they make a mistake. If they win, they choose to reinvest or secure. If they lose, the system instantly recalculates what's next. Their entire history is available, series by series, so they learn from their results instead of forgetting them.
The impact
BetOptimizer reached profitability within three months of launch. The landing page earnings simulator is the main conversion driver: visitors who use it have a sign-up rate four times higher than those who don't. The smart alert system reduced stake entry errors by 60%, directly improving satisfaction and retention. The archive page, initially conceived as a simple history, became an analysis tool that users consult daily to refine their strategy.
I knew exactly what I wanted but had no idea how to build it technically. Opsidius turned my specifications into a smooth, intuitive application. The simulator and series system work exactly as I envisioned, and the smart alerts add a safety layer my users love.
