Frequently Asked Questions
Is A Star Science free?
Yes — A Star Science is completely free to download and use. There are no ads, no in-app purchases, and no subscriptions. All 12 topics and 270 levels with 2,850 questions are available from day one.
Do I need to create an account?
No. You can use A Star Science in guest mode without providing any personal information. Your progress will be saved locally on your device. If you create an account, your progress syncs across devices and you can appear on the leaderboard.
What year levels does the app cover?
A Star Science covers Year 7–12 aligned to the Australian curriculum. Year 7–8 topics include Chemistry, Biology, Physics, Earth Science, and Scientific Method (20 levels each). Year 9–10 covers Chemistry II, Biology II, and Physics II with 30 levels each for deeper content, plus Space & Universe with 35 levels. Year 11–12 adds senior Biology III, Chemistry III and Physics III with 15 levels each. Every level is 10 questions.
What happens when I get a question wrong?
Every question has a detailed explanation shown the moment you answer. The question is also added to a review deck for that topic. Open Practice and choose “Review Mistakes” and the app serves you the questions you actually got wrong, hardest first. Each time you answer one correctly it is scheduled further into the future — the next day, then 3 days, a week, a fortnight, then over a month — and after five correct answers in a row it leaves the deck. Get it wrong again and it goes back to the front.
My progress disappeared — what happened?
If you were using guest mode, your progress is stored on your device. Uninstalling the app or clearing app data will erase it. To prevent this, create a free account so your progress is saved to the cloud. If you had an account and your progress is missing, please contact us.
Is there an Android version?
A Star Science is currently available on iOS only. An Android version is planned for a future release.
How do I delete my account?
You can delete your account directly in the app: go to Profile → Delete Account. This will permanently remove your account and all associated data. Alternatively, send an email to privacy@astarlearner.com with the subject line “Delete my account” and we will process your request within 30 days.
