# Exam Tracker vs ChemSpark

The clearest difference is in-app purchases: Exam Tracker at none against ChemSpark's 5. Exam Tracker also leads on ads (none vs shown). ChemSpark's advantage is update cadence (monthly vs every 38 months) and iOS requirement (17.6 vs 26.2). On price and device support there is nothing between them.

Both are free to download. ChemSpark sells 5 one-off in-app purchases. Exam Tracker asks for nothing beyond the download.

Exam Tracker ships an update every 38 months, ChemSpark monthly. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
