On the bottom left of your RepricerExpress Dashboard is the Price Changes panel which shows the number of recent price changes on your account.
You can see the number of products which have been repriced in the last hour, last 24 hours, and last seven days.
The dropdown menu allows you to filter the results by all channels or a specific channel. The number of SKUs is clickable and will take you to a list of SKUS whose price has changed recently.
Please note: The number of price changes is not the number of products, as the same product may be repriced more than once.
If you do want to check the last reprice time for a specific SKU, you can easily hover on it to show the 'Last repriced' time. More info here.
Our Youtube channel also provides a video guide.
