It's fantastic for targeting an audience when you know where they will be for a very low CPM. However, it's hard if you are a brick-and-mortar and want to truly measure the results. You need to get creative in ways to attribute site visits and purchases back to the campaign (unique coupon codes, etc.)
For the price and the features available, Localytics is one of the best options. It is more robust in areas that we don't need it to be and overall there could be simpler flows for sending push notifications or performing actions that you need to do every week. Also, the data it sends back on how push notifications perform is basically useless. There needs to be more explanation on the impact notifications have on users. The data would always say that notifications drove less engagement but we would see engagement go up every time we sent a notification.
The biggest thing I would like to see with Localytics is the capability for more correlations. The limited amount of correlations available does restrict the type of analyses that could be done with the data.
An easier interface to move data into Microsoft Excel would be very useful, rather than creating annoying workarounds.
More/better automatically scheduled reporting, as well as an Excel plug-in to access the data rather than being restricted to the Localytics interface.
It would take several weeks to hear back from the billing team. It took 3 months to resolve an invoice last year. Their technical support is very responsive. I would typically get a response in under 24 hrs.
