The ‘ProductCheck’ service uses location data to collect survey responses from consumers who have gone into a particular store of their own accord rather than recruited respondents.

Participants are sent in-store surveys about product packaging and visibility through the company’s mobile research app. They can also take photos and videos of products on-shelf via the app.

Chris St. Hilaire, chief executive and co-founder at MFour, said the tool combines "observed location data with event-triggered surveys that measure products’ on-shelf visibility and appeal". 

The launch follows the company’s recent addition of a tool tracking the effectiveness of in-store advertising, which sends consumers an exit survey after leaving the store to gauge brand awareness.
