General improvements and optimisations for a better experience.

Settings and the code-entry dialog now consistently use “Referral source”. Improved interface wording and stability.

The upgrade plan is now 90 days at the same price. Bookmark questions at any time while practising. Bug fixes and interface improvements.

Added a limited-time notice with a direct way to contact support about extending Pro access, plus usability improvements.

Improved purchase restoration with clearer results and error messages, and fixed retry handling after a restore failure.

New in-app Feedback: type and send your feedback right inside the app instead of switching to WhatsApp; the Report button next to questions is now called Feedback. Faster cross-device sync: after linking a sync code, the app refreshes your other device's records every 3 minutes while open, and answers upload within 60 seconds.

Updated App Store posters for a clearer introduction to the app.

Updated App Store images for a clearer overview of the app features.

Improved home shortcuts and interface presentation. Fixed an issue where processing the same purchase again could incorrectly extend Pro access more than once.

Revision checklist Every one of the nine topics now has a checklist that follows the official curriculum learning outcomes, so you can tick them off one by one. The outcomes that come up most often also carry "How it is asked" and "Scoring points", spelling out where candidates have lost marks, along with the years each was examined. Redesigned past-paper analysis The year breakdown is now a heatmap — one cell per exam, shaded by the marks it was worth — and each sub-topic lists the years it appeared in, so the parts examined every single year stand out at a glance. Also in this update • Chinese and English side by side throughout • Reference-table formulas use proper superscripts, e.g. J kg⁻¹ and ½mv² • Several English interface wordings corrected

• Redesigned practice filter: sorting, per-topic progress rings and a live question count • New wrong-answer and bookmark manager, with its entry restored on the home screen • Fixed a case where "practice data download failed" would never clear • Fixed the "times answered" count: questions you got wrong no longer show as new • Font size setting now applies across the whole app • Colour, navigation and image viewer refinements

• Teaching content fact-checked: quotations, dates and attributions corrected, unverifiable claims removed • Topic filter fixed: choosing a topic no longer pulls in questions from a similarly named topic • Interface text and stability fixes

Expanded Physics concepts, high-frequency points and quick references; added visual guides for stationary waves, diffraction gratings and internal resistance; improved practice.

Fixed curriculum content loading, added image zoom for study materials, and improved WhatsApp support links and error reporting.

Improved Physics quick-reference accuracy for thermal-radiation surfaces, particle energy during phase changes, and H-R diagram examples.

Cross-device sync now carries your per-question history: attempt counts, wrong-answer counts and last-answered dates travel with your sync code, so your practice calendar and "answered N times" badges follow you to a new device.

Removed an expired promotional pop-up and fixed minor issues for better stability.

Fixes an issue where the upgrade page could not load the purchase option. 180-day Pro can now be purchased.
