+### Accessing app analytics (only for paid users)
+
+Paid users can access analytics data for a particular app. Currently the following analytics endpoints are supported:
+- overview
+- noresultsearches
+- popularresults
+- popularsearches
+- popularfilters
+- geoip
+- latency
+
+#### Example
+
+By default the command will ping the overview endpoint
+
+```sh
+> abc app -a MyCoolApp
+
+Analytics(Overview) Results:
+No Result Searches
++-------+------+
+| COUNT | KEY  |
++-------+------+
+|   1   | blah |
+|   1   | gurr |
++-------+------+
+No Result Searches

+|   1   |     gru      |
+|  ...  |     ...      |
+|   1   | wonder woman |

+Search Volume Results

+To ping other analytics endpoints the `endpoint` flag can be used. For example
+
+```sh
+> abc app -a --endpoint=latency MyCoolApp
+
+Analytics(Latency) Results:
++-------+-----+
+| COUNT | KEY |
++-------+-----+
+|   2   |  0  |
+|  ..   | ..  |
+|   0   | 10  |
