Alert 2020
Read full descriptionHide full description
Simple, secure and robust major-incident management for shopping and retail centres. Shop Alert is widely recognised as a generic term within the UK shopping centre sector and remains the major incident-management system of choice for many centres and arenas nationwide, equipping them with the ability to communicate instantly with retail units. It is a simple, speedy, secure and powerful system. Huge challenges continue to face owners and managers of crowded places in coordinating their resources in the event of major incidents such as a bomb or firearms-related terrorist attacks, as have been experienced all too often in recent years. It is the efficient way to communicate with centre-staff and tenants. Invaluable in a major incident but also day-to-day within seconds you can receive notifications about lost children, shop lifters, counterfeit money circulating, upcoming events, recycling targets, inspections, audits, information and even the odd fun interaction.

Verdict
The clearest difference is update cadence: CleanOnn at every 5 weeks against Alert 2020's every 5 months. Alert 2020's advantage is iOS requirement (9.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
