Your estimates are wrong.
We all know it.

Software teams struggle with estimation because existing tools either oversimplify or overcomplicate the process. You end up with tasks marked as “done” but projects that are never really finished.

Missing Deadlines

Projects consistently run over time with no visibility into why

Poor Team Alignment

Everyone has different ideas about task complexity and timing

Unrealistic Expectations

Stakeholders lose trust when timelines become meaningless

The right balance of structure and simplicity.

Estimation happens in your team, planning happens in our tool, and progress tracking happens in real-time.

Collaborative Estimation

Share a link with your team. Everyone estimates together using T-shirt sizing, then maps those sizes to actual developer days. No more guessing alone.
