Great app that I use on almost every flight

I’ve been using this app for a few years. I use it on almost every flight out of curiosity to look up certain numbers I hear on frequency. The database had not been updated in nearly 2 years and it was becoming less useful so I reached out to the developer and asked when the update would happen and within a couple days he provided an update. Great response time and follow up.

No longer updated - stale data

Database is no longer updated. Was a great little app, but it is no longer useful. Please consider updating. I would pay for it.
