Propwash (formerly Cleared) is a study app for the Part 107 remote pilot knowledge test. It is built for short sessions: answer a few questions, read why the right answer is right, and see how ready you are.
Email tomnguyentpm@gmail.com and you will hear back within a couple of days. Telling us your device and what you were doing when something went wrong makes it much faster to fix.
Please tell us. Email the question text and the answer you expected, and we will check it against the source document it cites. Corrections ship in an app update.
On your device only. There are no accounts and no cloud sync, so deleting the app deletes your progress. See the privacy policy for the full picture.
The knowledge test is booked through the FAA and its testing centers, not through Propwash. Check the FAA's own pages for the current process and fee.
Propwash is independent study material and is not affiliated with or endorsed by the FAA.
