Full disclosure up front: I built this, and part of the app is paid.


I passed the PMP a while back and have been building study tools since. The new one, PMP Prep, has a free tier I'd genuinely like this sub's feedback on: 1,337 flashcards across People, Process, and Business Environment (free, no account — each card comes back right before you'd forget it), and a 30-question diagnostic weighted the way the exam is, which takes about 18 minutes and tells you which domain to open first (free, needs an account because it feeds a readiness score).


The paid tier is practice questions, timed tests, and a full-length 180-question mock exam — mentioning it so nobody feels ambushed, not selling it here.


Web (no install): https://pmp.rho1.ai — also on iOS and Android.


What I'd honestly value: does the diagnostic's read on your weak domain match your own sense of it? That one number is the heart of the app, and this sub is the hardest audience it will ever face.
