Well, not "exactly as I mentioned" since there seems to be no location-based results for images and events, tourist attractions
nearby, and detection has to be
automatic. Also there's no mention about results based on social media preferences.
I think it would be beneficial for your app to include the precise description you just mentioned: that the app has a mart tagging search engine which fetches all relevant tags... I'm aware it's in the bullet points in the app description, but a little more than a bullet point would be more convincing for the viewer to actually download your app. Just mentioning "smart" without telling the user why it is "smart" is usually not enough.
I mean, the app is posed as being "Smart", so make the word "Smart" your pivot point in making your app stand out from the rest.
P.S. You may want to fix that crashing issue in lower memory/resolution screens as soon as possible - your app will be smarter if it automatically adjusts its use of resources to prevent such crashing issue.
