App is free, but it’s $9.99 per year.
Response from developer
Thanks for taking the time to write a review! To clarify, the app has a 7-day free trial, after which it costs $9.99 per year. It has an easy-to-use full-text search function of NTSB and international accident report data, notifications when new reports are published and a view optimized for the iPhone/iPad, none of which can be found elsewhere. If you'd like to give the app another try, please let me know via email to support@accidents.app, I'd be happy to set up an extended trial for you.
