Mastt Schedule

Mastt Schedule is a browser-based construction scheduling platform for project owners, developers and project management consultants. It suits teams that need to create or track project timelines and review progress across linked projects. Its strongest case is combining schedule tracking with client sharing and program dashboards; teams needing a mobile app should look elsewhere.

Overview

Teams can build schedules from scratch or use templates to set standard phases and milestones. Importing Microsoft Project XML and Primavera P6 XER files gives teams a route to track and report on schedules created in those tools. Gantt views show activity timing, while task checklists provide a way to follow activity progress.

Progress dashboards summarize schedules, and invited clients can view schedule information through read-only links or PDF downloads. Program dashboards consolidate information from linked projects, which is useful for reviews across a construction program rather than just one timeline.

Key features

Scheduling and reporting

Imports are useful for organizations with established Microsoft Project or Primavera P6 schedules; templates suit teams seeking more consistent phases and milestones, while building from scratch allows a different structure. Gantt charts and checklists cover both schedule-level visibility and activity tracking. Client sharing is deliberately view-only, so it supports reporting without providing clients an editing route.

Security and support

Mastt says it uses TLS 1.2 or higher and conducts regular penetration testing with NCC Group. It hosts customer data in Microsoft Azure data centers in the US for the Americas and in Australia for Australia and other customers. Support ranges from self-service tutorials and resources to phone, email or help-center support, with priority handling for Enterprise customers.

Pricing

The free Starter plan costs nothing, is billed month-to-month and includes the first project with no credit card required. Its one-project cap makes it a sensible way to start a single schedule, but not to manage a broader program.

Professional costs $165 a month, billed month-to-month at an average cost per project. It includes unlimited users, and project licences can be added or reduced as needed. Cost, Risk, Schedule and Dashboard modules are included, making it the more suitable choice for teams that need multiple projects or broader project visibility. The price is tied to project licences rather than a stated user cap.

Enterprise has custom pricing and includes unlimited projects, programs and portfolios, ERP and business-system integrations, SSO and dedicated customer success. It fits organizations needing those integrations or portfolio scale, though the move from a free single project to custom pricing is a substantial step. Agent is also custom pricing and can be added to any Platform plan or bought standalone; it includes AI agent features, workflows and integrations.

Platforms

Mastt Schedule runs in a modern web browser and requires no special software or hardware. There are no mobile apps, so teams that need a dedicated phone or tablet app should consider alternatives with mobile support.

Who it's for

This is a focused option for construction owners, developers and project management consultants who need schedules, progress reporting and client visibility in a browser. The free plan suits one-project use; Professional is better for teams scaling project licences and using several modules; Enterprise is aimed at organizations that need unlimited program and portfolio scope or business-system integrations. It is less suitable for people who require mobile apps.

Pros and cons

• Pros: Microsoft Project XML and Primavera P6 XER imports help teams bring existing schedules into a tracking and reporting workflow.
• Pros: Gantt views, activity checklists, client sharing and program dashboards span activity tracking through portfolio review.
• Pros: Professional allows project licences to be adjusted and includes unlimited users, avoiding a stated per-user cap.
• Cons: Starter is limited to one project, so multi-project use requires a paid plan.
• Cons: There are no mobile apps; access is through a browser.
• Cons: Enterprise and Agent use custom pricing, which makes their cost less straightforward to assess than Starter or Professional.

Alternatives

Browse Construction Scheduling Software for more options in the category. Consider usBIM.platform if you want a free basic configuration with 10 GB of cloud storage and online applications, or need support for Android, iOS or Windows as well as web.

Open Planner Studio is a better fit for readers seeking free, open-source software with Gantt charts, critical-path analysis and resource planning across Linux, macOS, web or Windows, and no per-seat licence fees. Trimble Quadri is worth considering if a free read-only model-viewing tool with commenting and measurement is the priority, or if self-hosted and API options matter.

Asta Powerproject may suit a single Windows-PC user prepared to pay £695 a year, excluding VAT, for its single-user subscription. LookAhead is another paid option with Android, iOS and web platforms.

Nialli Visual Planner offers a 30-day full-access trial with no credit card required and a single-plan subscription at $1,400 a year; it is an option for readers who want a trial before committing. Oracle Primavera Cloud is a paid alternative with Android, iOS, API and web platforms and named-user monthly services.

TeamGantt is worth comparing if a web, iOS and Android option with a free plan is more useful; its Personal plan is limited to one user, one project and 40 tasks.

Verdict

Mastt Schedule is a strong match for construction teams that want browser-based schedule creation, progress reporting and project-level or program-level visibility, especially when they already use Microsoft Project or Primavera P6. The free plan is a practical single-project start, and Professional adds adjustable project licences and broader modules. Look elsewhere if mobile apps are essential or if the single-project free tier is not enough and a custom-priced Enterprise plan is too large a commitment.
