Unusable Without in App Purchase – Geotag Photos Pro 2 Review

I downloaded the app hoping to give it a try. I'd gladly pay for it if I find it useful. Until you buy the full version you can't record a trip. So, there is no trial, useless unless you buy the full version with the in-app purchase. How do I know it will work as expected?
