Questions, answered plainly.

You buy time in packs, and each pack is a single payment: 1 month for US$9.99, 3 months for US$24.99 or 12 months for US$83.99. Everything is included, with no tiers and no add-ons.

Your price is set by your region at checkout. UK, EU and India prices include VAT/GST; US and Canada prices are before tax.

Your price is set by where you are when you buy, so you see the currency for your region. Each pack is priced at the time you buy it.

Payments are processed by Link, a service of Stripe, which is the merchant of record for every purchase. Your card statement will show LINK.COM* STRAVORIS SA, and your receipt comes from Link.

Yes - 14 days, one free trial per email address. No card is taken to start, so there’s nothing to cancel: when the 14 days are up, practice locks until you buy a pack. We’ll email you 3 days before it ends, so it doesn’t catch you out.

No. You start the 14-day free trial without entering any card details. You only pay if you decide to buy a pack, during the trial or after it.

No. A pack bought while you still have time left starts when that time ends, so the rest of your trial is kept and the pack’s full length is added after it.

Practice locks until you buy a pack. Your progress and history are kept, so when you buy, you pick up exactly where you left off.

No. Each pack is a single payment and nothing renews automatically, so there’s nothing to cancel and no lock-in. When your time runs out, practice locks until you buy more. We’ll email you a week before, and the day before, your time runs out.

Yes. We email you 7 days and 1 day before your access ends, and 3 days before a free trial ends. Every reminder has a “Stop reminder emails” link, and you can turn them off or back on from your Account page.

Yes, within 14 days of buying a pack. A pack that hasn’t started yet is refunded in full. A pack that has started is converted to a 1-month pack, and we refund the difference. A started 1-month pack isn’t refundable. After 14 days, packs aren’t refundable except where the law requires it. To ask, email support@stravoris.com from your account email address. The full rules are in our Terms.

Yes. Every account has an invite code on its Account page. When a friend adds your code, they get 15 days straight away, and you get 15 days two weeks after they buy their first pack. There’s no limit on how many friends you invite.

20 subjects across the undergraduate medical curriculum, from preclinical foundations through to clinical specialties - 160,000+ questions across 1,100+ topics. You can work through a subject, or take a hospital unit and practise across every subject it draws on.

It’s the second way to study. Instead of picking a subject, you pick the hospital unit you’re heading to - Emergency & Trauma, say, or Nephrology & Dialysis - and your session is built from the knowledge that unit’s work draws on, across every subject involved. Between them the units draw on more than 123,000 of the questions. When the answer is revealed, it also tells you why that question matters on that unit. It’s included in every pack; there’s nothing extra to buy.

Thirty-two, curated to cover the placements you’re most likely to be sent to and grouped into seven areas of care - emergency and critical care, perioperative, medical and surgical specialties, women’s and children’s health, mental health, diagnostics, and outpatients and hospital pharmacy. Units are named differently from one hospital to the next, so each carries its other names as well - 163 in all, so A&E, ED, ER and Casualty all point to the same unit. You can browse the list and read about each unit inside the app.

No. The choice is made each time you start a session, so you can work through a subject one day and a hospital unit the next. Your review and progress are kept for both.

Yes. Answer 10 questions in a day and it counts towards your streak, in your own time zone. Study sessions and sessions built for a hospital unit count; exams don’t. Miss a day and your streak survives: you have two rest days in any 30, used automatically. You’ll find it on your Home page.

You earn badges as you practise. In most subjects, badges come at 25, 250 and 1,000 different questions answered, and each hospital unit has the same, earned in sessions built for that unit. There are also milestone badges for the questions you’ve answered overall, the questions you got wrong and later got right, and your daily streak. Exam answers don’t count.

Study mode shows the answer and explanation as you go, so you learn in the moment - and, where hospital units draw on the question, which units those are and why it matters on each. The units draw on more than 123,000 of the questions between them; on the rest, no units are shown. Exam mode is a sealed, timed paper with no feedback until you submit, so you can test yourself the way a real exam works. Exam mode is on the subject path; a session built for a hospital unit is always study mode, because the point there is to arrive knowing how the knowledge gets used.

There is more on both in how it works.

They are pitched at the undergraduate medical level - the material you cover across your degree, from preclinical foundations through to clinical specialties. So whatever year you are in, the questions match what you are actually studying.

Yes. Explanations teach the reasoning behind an answer, so you understand why it is right rather than only that it is.

We keep this straightforward and explain it in full in our Privacy Policy. In short: your account, your practice history, the time zone we use for your daily streak, and billing details handled by Link, a service of Stripe. You can turn off reminder emails at any time.

Email privacy@stravoris.com from your account email address and we will remove your account and data. Deleting your account forfeits any unused time, so if you’re within the 14-day refund window, ask for your refund first.
