CellAlert: Deadline Reminders

CellAlert is the companion app for the CellAlert deadline-monitoring service. A CellAlert account is required to use this app (free to create at cellalert.app).

Important deadlines often slumber in a spreadsheet and only surface once it's too late: a missed inspection, an expired certificate, a forgotten contract renewal. CellAlert turns those dates into monitored deadlines and reminds you in time — by email, in your calendar and in this app. With the app your deadlines are always with you, on the go.

How the app works with CellAlert:
• Deadlines are created in the CellAlert service from your spreadsheets (Excel, LibreOffice, FileMaker).
• This app shows them on mobile: today, this week, overdue — and reminds you in time.
• Acknowledge and review the history — audit-ready.

WHAT CELLALERT IS MADE FOR
• Inspections & maintenance: safety checks, servicing, equipment tests, maintenance plans.
• Certificates & licenses: keep expiry dates in view before they lapse.
• Contracts: renewal and cancellation deadlines on your radar in time.
• Compliance & audit: re-certification, calibration cycles, proof obligations.

APP FEATURES
• Reminders & calendar — email plus calendar subscription for Outlook, Google and Apple.
• Priority & escalation — critical deadlines remind daily until someone acknowledges.
• Recurring deadlines, filters (today, this week, overdue) and a matrix view.
• Team — deadlines belong to the organization, with assigned responsibilities.

Hosted in Germany, GDPR-compliant. Only the deadline is stored — never your file.
