We use AppFollow only for customer service, but it has a lot of features that would be great for the marketing and development team. A good bit of the features we do not use, as there is simply not a use case for it. The best feature that we get from AppFollow is the ability to import Apple reviews into Zendesk for agents to respond to. This has been a great time saver for us.
One of AppFollow's core features is their keyword rankings. With both our Android and iOS app I'm able to view the keyword and position of our app for that keyword. I'm also able to toggle the dates and see the history positioning. Not only is this available for US app stores but global app stores. This is extremely helpful when A/B testing.
Another key feature to AppFollow is their integrations. Being able to integrate AppFollow with Slack has been extremely helpful. With this integration, we are able to see reviews in real-time and respond to them right from Slack.
We don't check AppFollow every day. With that said, it's important for us to get daily and weekly reports from AppFollow about our ASO performance. You can easily check which reports you would like, how often, and where to in a matter of seconds.
While App Annie is extremely robust and pulls in data from acquisition channels, app stores, and elsewhere, it can be quite overwhelming at times. If you are looking for more simple and just keyword positioning then definitely look at AppFollow. Apart from the two platforms themselves, I've had numerous contact experiences with both AppFollow and App Annie. The winner is definitely AppFollow with a less aggressive approach and a higher willingness to go above and beyond to make sure all questions are answered. With App Annie I was bombarded with a ton of sleazy, sales emails to purchase their product.
