Plan your IB Chemistry revision, week by week. ChemPlan IB builds you a personalised study schedule based on your exam date, your level (SL or HL), and the topics you have already covered. It takes about 60 seconds to set up. How it works Select your exam session (May or November) and choose SL or HL. Tick off any topics you have already studied. Tap Generate. The app divides the remaining topics across your available weeks, weighted by difficulty, and adds dedicated revision weeks before your exam. That is it. No account needed, no subscription, no ads. What you get A week-by-week study plan covering all 22 IB Chemistry topics across Structure 1-3 and Reactivity 1-3. Daily task breakdowns so you know exactly what to study each day. Progress tracking: tap to mark days complete and watch your overall percentage climb. A built-in Pomodoro study timer with streak tracking to help you stay focused. Three topic ordering modes: Chronological (syllabus order), Recommended (builds concepts logically), or Custom (drag and drop your own order). Adjustable revision weeks (1-4 weeks) before your exam for past papers and final review. Daily push notification reminders at your chosen time, telling you exactly which topic is scheduled. Data backup and restore: export your entire plan as a text file via the iOS share sheet, and import it on any device. Light and dark mode. What this app does not do ChemPlan IB is a planning tool, not a textbook. It organises your revision schedule but does not contain lesson content, practice questions, or marking schemes. Each topic links to free study material on chemistrymadeeasy.com if you need it. The app works entirely offline and stores all data on your device. Nothing is uploaded to any server. Who it is for IB Chemistry students sitting their exams in 2026 or 2027 who want a clear, structured revision plan without the guesswork. Built by a chemistry teacher.

Verdict

The call

The clearest difference is in-app purchases: ChemPlan at none against ChemSpark's 5. ChemPlan also leads on ads (none vs shown) and iOS requirement (15.0 vs 17.6). On price and device support there is nothing between them.
