Streaks, past interviews and a lot of fixes. - Your daily streak now actually counts up. It used to reset instead of growing. - Past interviews: every AI mock interview report is saved and listed, so you can look back at your scores. - Practice tests and study guides now unlock exactly as their cards show. - Section times and question counts now match the real battery layout everywhere in the app. - Clearer messages if a purchase or an answer can't go through. - Stability: if a screen hits an error you can try again instead of the app closing, and we now hear about it so we can fix it.

Mechanical section upgrade, plus fixes. - 51 mechanical diagrams redrawn so the picture matches the question: meshing gears actually touch, hydraulic pistons connect, and ropes run over their pulleys. - 229 new mechanical questions (130 to 359): belt and chain drives, block and tackle, friction on ramps, hydraulics, springs and more. Your practice batteries and drills now go much further before repeating. - New mechanical drill topics: heat and expansion, balance, and structures. Fixes: - Send Feedback now reaches us. Before this update, messages sent from inside the app never arrived. If you wrote to us, please send it again. - The optional email step in setup now works. Before, the address you entered was never saved. - Terms and Privacy links now open pipeprepai.com.

Subscriptions now work. If you tried to go Pro before this update and the purchase failed, that was our fault, not yours — the subscription products were never finished on our end, so every attempt failed no matter what. Nothing was ever charged. This update fixes it, and the paywall now tells you plainly when plans can't be loaded instead of showing a button that can't work. Application-window reminders now work properly too. Setting a reminder for your local previously only scheduled a notification on your phone, using the date the app had cached. Now your local is registered with our tracker, so if a window opens early, closes late, or opens unexpectedly, you hear about it — even if you haven't opened the app in weeks. Turning the reminder off removes you. Already subscribed? Tap Restore on the paywall or in Settings.

Question bank accuracy pass. Every answer key in the math and mechanical sections was re-verified against the math itself rather than spot-checked. A small number of items had the wrong choice marked, offered two answers that were mathematically identical, or showed a correct value that wasn't among the choices at all. All corrected, with those explanations rewritten to teach the method cleanly. Answer choices were also rebalanced. The correct answer now lands on A, B, C and D about equally often, so practising here trains the material instead of a guessing pattern. Your history is protected: where a question's choices changed, that item's old answer is cleared rather than re-scored against options you never saw.

The UA locals directory grew from 50 locals to 220 — nearly every plumber, pipefitter, steamfitter, HVAC-R, and sprinkler-fitter local in the country, each with how to apply, what its selection process looks like, and its application window when the local publishes one. Set your local and the app paces your study plan to its deadline. Also fixed: the in-app "leave a review" link and the support contact address.
