I’ve experimented with using Databricks SQL Warehouse as the backend for a web app, and it has its advantages, but like any tool, it depends on your specific requirements.

From my experience, it’s great for handling large datasets and performing heavy analytics. If your web app involves complex data analysis or big data, Databricks could be a solid choice. The SQL integration is smooth, and performance is generally strong.

On another note, have you checked out the latest trends in mobile app development? I came across an insightful article called 'Mobile Apps Future: Unveiling the Top Trends Shaping the Next Generation'. It covers the shifting landscape of mobile apps and could provide some useful perspectives for your project.

As for Databricks’ own view, they’ll obviously promote its scalability and analytics capabilities. But like with any tool, it’s important to recognize its best use cases.

One thing to keep in mind: be cautious of costs as you scale up. Sometimes the pricing can be a bit of a surprise. Also, the learning curve might be steep for your team, so make sure they’re comfortable with it.

I recommend testing it out on a smaller project first to see how well it aligns with your needs.
