Sporting 3Trio is a simple, privacy-first planning tool that helps you improve your time estimates by comparing what you expected with what actually happened. Plan your work, record real effort, and use your personal history to make future estimates more realistic.
Estimate Before You Start
Set an expected duration for each task using hours, days, or your preferred effort scale. Create a clear baseline before beginning your work.
Track Actual Effort
Record the time or effort spent after completing a task. Keeping estimates and actual results together makes it easier to understand how your planning performs.
Discover Your Patterns
Review historical estimates alongside actual results to identify recurring differences, improve forecasting habits, and build greater confidence when planning upcoming work.
Organize Your Work
Keep effort records connected to projects and tasks. A clean, focused interface makes it easy to add entries, review previous work, and maintain a useful personal planning history.
Fully Offline
Sportingbent 3Trio works without an internet connection. Your information is stored locally on your device using SQLite, allowing you to access and manage your records wherever you work.
Privacy by Design
No account is required. Your planning records remain on your device, with no uploads, cloud synchronization, background connections, or tracking of your activity.
Whether you are a developer, designer, consultant, freelancer, student, or project manager, Sportingbent 3Trio gives you a practical way to learn from your own effort history. Instead of relying only on intuition, use your previous estimates and actual results to make better decisions.
Start recording your estimates, compare them with real outcomes, recognize your planning patterns, and build a more reliable approach to managing your time and projects—all while keeping your data private and offline.
