I think your software is excellent! I needed to compare 2 Access files and your software was able to identify differences and the information was presented in a very useful manner. You saved me a lot of time and effort.

I always use this to compare Access objects, table data, and code. The developer is great at offering support and fixing any issues I have had with previous versions of his software.

After testing numerous of data sync and merging tools in the market, this tool is the most intuitive and also the powerful one. I am using it for sensory data merging with time series data and also disaster recovery merging because of highly vulnerable end points in our test cases. I wish it has also support on non-Windows OS's but every beauty has own beast.

It was a great experience using your tool trying to recover a db even though the recovery was cancelled. Your tool is amazing.

In my job, I use different builds of my Access database, and I need to constantly go back and forth between them to determine what has changed. For me, this can be table data, queries, forms, and code. AccdbMerge makes it so easy to see the changes between different access databases. I use it multiple times every day. Konstantin (the developer) is always responsive and offers great support whenever I have questions. I love this software!

I used the tool to propagate changes made in one Access DB to its copies distributed across departments of my company. With the tool, I was able to do it effortlessly. It was a timesaver for me.
