iPhone
Pick your state, role, project type, and last work date. Three lien deadlines instant. Add to iPhone Calendar with one tap. Pin to Lock Screen.
LienClock is the deadline calculator for U.S. mechanics liens.
WHAT YOU TAP AND WHAT YOU GET BACK
Pick your state. Pick your role (general contractor, subcontractor, supplier). Pick project type (private, public federal Miller Act, public state Little Miller Act). Pick last work date. Tap Calculate. Three deadline cards appear: Preliminary Notice, Mechanics Lien Filing, and (for public projects) Bond Claim Notice. Each card shows days remaining, the actual due date, and the published statute reference (for example, Cal. Civ. Code SS 8204-8216).
Tap Add to Calendar to write the deadline straight into your iPhone Calendar with alerts at 30, 7, and 1 day before. Tap Set Reminder to schedule local notifications you control. Tap Save to Projects to track the job for the duration of the work.
DAY ONE FEATURES
- 50-state + Miller Act deadline calculator with the actual statute reference on every result.
- iPhone Calendar direct write - deadlines become real Calendar events with built-in alerts.

50 STATES + FEDERAL MILLER ACT
Pro covers all 50 states plus DC and the Federal Miller Act, each with its published statute reference. The free tier covers six anchor states - California, Texas, Florida, New York, Illinois, and Pennsylvania - plus the Federal Miller Act.
CALCULATOR-FIRST. PHONE-FIRST. NO LOGIN.
Open the app and start. The app stays on this iPhone - no account, no signup, no email, no cloud sync. The deadline math is rule-based, no analytics. Calendar permission is requested only when you tap Add to Calendar; Notifications permission only when you tap Set Reminder.
STRICT UPL BOUNDARY
LienClock calculates deadlines from publicly available state and federal mechanics lien statutes. It does not recommend specific filing strategies, draft actual lien claim forms, predict outcomes, or substitute for a licensed construction attorney. For lien filing decisions or complex disputes, consult a construction attorney in your state.
IPHONE-ONLY BY DESIGN
LienClock is built exclusively for iPhone. iPad and Mac are not supported. The field tool belongs on the phone in the contractor's pocket.
DATA STORAGE
LienClock stores all project data locally on this iPhone. The app does not include built-in JSON export, JSON import, or in-app archive backup. Your saved projects are included in standard iOS Backups when iCloud Backup or Finder/iTunes Backup is enabled. Deadlines you write to your iPhone Calendar persist independently of LienClock - even if you delete LienClock, the Calendar events stay in your Calendar.
