The developers at Supertop, makers of Castro for iPhone, write:

Castro 1.0.4 had received 10 App Store reviews in the first three days of its release. After three days 1.0.5 had 48.

We wondered if the dramatic increase was a coincidence so when 1.0.6 was released we left the request out. Three days later we had only 4 new reviews, after a week we had 8. It took three weeks to get 24 reviews, half of what we had after three days for the previous version.

It’s good to know that asking for something nicely on the Internet can still produce satisfying results. Castro’s audience is certainly used to reading release notes, so until Apple changes how App Store reviews are reset for each app update, this might just work as a viable alternative to review prompts.
