About this app

Quantum Harbor is a freelance delivery command center for independent professionals managing multiple clients and projects at once. Track active project value, delivery risk, milestones, and billing readiness — all offline, all in one app.
Built for freelancers who need more than a to-do list — a full operational view of their business.
Projects — start from ready-made templates: brand launch, website build, automation sprint, retainer, or audit. Each template auto-creates milestones and invoice checks. See progress, due dates, risk score, and latest estimate at a glance for every active project.
Clients — keep local records for every client with hourly rate, payment terms, and delivery notes. Know exactly what each client expects: Friday demos, PO on every milestone, upfront payment, or grouped change orders.
Milestones — move deliverables through planned, active, blocked, and delivered states with a single tap. Each milestone shows estimated hours, due day, and watch items so nothing slips through without an approver.
Finance — calculate project estimates with hours, buffer percentage, and client rate. The invoice checklist ensures every bill goes out with signed scope, milestone evidence, expenses checked, and a follow-up date set. Save estimates and compare across projects.
Reports — offline health summary across your entire business: delivery health score, billing readiness, blocked milestones, and total saved estimates. Know your risk index before it becomes a problem.
Quantum Harbor is for freelancers who want to run their work like a business — with clear delivery commitments, clean client records, and invoices that are always ready to send
