About this app

The mobile companion for the CellAlert deadline monitoring service.

A CellAlert account is required — this app does not work on its own. Accounts are free at cellalert.app.

Important deadlines sleep in a spreadsheet and only surface once it is 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.

HOW THE APP FITS IN
- Deadlines are created in the CellAlert service from your spreadsheets (Excel, LibreOffice, FileMaker)
- This app shows them on your phone: today, this week, overdue
- Acknowledge a deadline and review the history — audit ready

WHAT TEAMS USE IT FOR
- Inspections and maintenance: safety checks, servicing, equipment tests, maintenance schedules
- Certificates and licences: expiry dates in view before they lapse
- Contracts: renewal and cancellation deadlines on the radar in time
- Compliance and audit: recertification, calibration cycles, proof obligations

IN THE APP
- Reminders and calendar: email plus a calendar subscription for Outlook, Google and Apple Calendar
- Priority and escalation: critical deadlines remind daily until someone acknowledges
- Recurring deadlines, filters for today, this week and overdue, plus a matrix view
- Team: deadlines belong to the organisation, with assigned owners

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

Sign in with your CellAlert account and stop missing deadlines.
