Reviewers consistently praise Project Planner! for being easy to learn, cleanly designed, and especially useful for teams already working in Microsoft Teams. They say it keeps planning, task tracking, timelines, dependencies, and collaboration in one place, with Gantt views that make progress and milestones easy to understand. Several also highlight its ability to manage multiple projects without a heavy setup or training burden. Criticism is light but consistent: reviewers want more templates, stronger reporting and customization, calendar and email integrations, clearer notifications, and some automation.
