StampReady is the exam-prep app built by a licensed P.E. for engineers preparing to sit for the NCEES FE or PE. WHAT YOU GET - Timed practice tests with a pre-submit Review screen: tap any question in the grid to jump back, filter to your flagged or unanswered items, and submit when you are ready. - 5,400+ multiple-choice questions across 22 engineering disciplines, including PE Civil depths (Transportation, Structural, Geotechnical, Water Resources, Construction), PE Mechanical (HVAC, Thermal), PE Electrical Power, PE Environmental, PE Chemical, and all FE disciplines (Mechanical, Electrical/Computer, Chemical, Civil, Environmental, Industrial). - Flag questions during a session and come back to them later. Your marked items persist to your account, not just the session, and surface on your dashboard for focused review. - Readiness diagnostic that scores your weakest topics from a 30-question assessment and feeds them into a targeted study plan. - 50-state licensure checklist with direct links to your state board and to NCEES so you can see exactly what your state requires. - Real-time "weeks to exam" countdown that keeps you on pace. EVERY QUESTION IS VETTED Every multiple-choice question in this iOS app is forward-derived from the published reference handbooks (we compute a realistic numeric answer first, then write the stem around it, never back-fit). PRIVACY Anonymous product analytics. You own your practice history, and you can delete your account from the Profile screen at any time. Questions?

Verdict

The call

The clearest difference is price: StampReady at Free against Mechanical Engineering Lab's $6.99. StampReady also leads on iOS requirement (13.0 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
