Features
Read full description

For all invitees to the CATCheckpoint Defects Identification and Remedial Management system. This App is a companion App and requires you to be invited. This app allows Main Contractors to initiate and create defects inspections and assign to the relevant subcontractor and quickly update results during re-inspections. The subcontractors can update finished work on the fly and notify the main contractor when remedial work is completed. Defects status can be updated on the App by a main contractor, consultant or subcontractor so information is always live. If you are a consultant you can initiate inspections using our pre-emptive defects lists.

Verdict

The call

The clearest difference is ads: CATCheckpoint at none against App Lock's shown. CATCheckpoint also leads on iOS requirement (12.0 vs 16.0). App Lock's advantage is update cadence (fortnightly vs every 2 months). On price, in-app purchases and device support there is nothing between them.
