Question 1

What platforms does The Grammar Index support?

Accepted Answer

The Grammar Index is available as a web application, a Windows desktop app, and native mobile apps for iOS and Android. Your license key works across all platforms — buy once, use everywhere.

Question 2

Is there a quiz?

Accepted Answer

Yes — every edition includes a built-in five-question multiple-choice quiz. Open the topics you want to revise, then tap the Quiz button: the app builds a tailored quiz from the entries you have actually studied, with randomised questions, randomised answer options, and freshly chosen distractors on every retake. Score, feedback, and a 'try again with new questions' button.

Question 3

Is there a spelling test?

Accepted Answer

Yes — the Key Stage 2 & 3 edition includes a Spelling Test (on web, Windows, iOS and Android). Each round gives 20 sentences with a word missing and a row of 3-5 spellings where only one is correct; the pupil spots the right spelling and types it in, which reinforces both visual recognition and recall (device autocorrect is switched off so it can't spell the word for them). It draws on 1,000 curriculum spelling words — high-frequency words, homophones, commonly misspelled words, the Year 3-6 statutory lists, and Science, Maths, Geography and History vocabulary — with age-appropriate, often funny sentences. Words, options and distractors are re-rolled every round, and a tiered result tells pupils how they did and which words to practise. The free preview includes a fixed 20-word sample; a licence unlocks the full bank.

Question 4

Can teachers choose which topics pupils see?

Accepted Answer

Yes — the Key Stage 2 & 3 edition has a Custom list. Tap Custom, tick the topics you want, and only those appear on the home screen; the choice is saved and reappears next time the app opens. A teacher can curate a focused set — this week's topics, a revision list, or the trickiest areas — so pupils return to the same directed list each lesson instead of the full catalogue. The selection is stored per device (it doesn't sync across the class automatically), so it's set once on each pupil's machine. Used well, it turns the reference into a guided learning plan rather than a free-for-all.

Question 5

Is there a version for younger pupils?

Accepted Answer

Yes — the new Key Stage 2 & 3 edition is a child-friendly version designed for ages 7-13 and built for use across the major school platforms: Google Classroom, Microsoft Teams for Education, and Apple Store for Education. The content is aligned with the UK National Curriculum English programme of study (DfE glossary, DFE-00184-2013), so it covers every grammar term schools are expected to teach at Key Stages 2 and 3 — including main, subordinate (dependent), relative (adjective), adverbial, and noun clauses, plus a full Phonics section. Vocabulary and examples are written for younger readers; each topic includes right examples, a wrong example with an explanation, and a little grammar joke. It also includes a quick quiz and a Spelling Test built on 1,000 curriculum spelling words. It lives at keystage.grammarindex.com and is unlocked with a Gift / Sponsorship licence (see the pricing page for school, class, and district tiers).

Question 6

Is there a free version?

Accepted Answer

Yes! You can access 10 grammar entries for free on the web with no registration required. To unlock all entries, purchase a license.

Question 7

How does licensing work?

Accepted Answer

When you purchase The Grammar Index, you receive a license key (e.g., GI-XXXX-XXXX-XXXX). Enter this key to activate the app on your devices. Each tier allows a different number of device activations.

Question 8

Can I use my license on multiple devices?

Accepted Answer

Yes. Every paid licence covers 2 devices per seat. Individual is 1 seat (2 devices); Team is 10 or 30 seats; Institution is 100, 500, or 1,000 seats; Gift / Sponsorship goes up to 10,000 seats.

Question 9

Is the payment a one-time purchase or a subscription?

Accepted Answer

All payments are one-time. Once you purchase a license, it lasts forever on your activated devices. There are no recurring fees.

Question 10

How do I log in to the web version?

Accepted Answer

Go to the Login page and enter the email address used during purchase along with your license key. No password is needed — your license key is your credential.

Question 11

How do I activate the desktop or mobile app?

Accepted Answer

Launch The Grammar Index app on your Windows PC, Android device, or iOS device and enter your license key when prompted. The key is stored locally on the device, so the app works offline once activated.

Question 12

What happens if I reach my device limit?

Accepted Answer

You've reached the device limit on your licence. If you're replacing an older device (new laptop, new phone), visit grammarindex.com/my-devices to free up a seat — enter your email and key, we'll email a verification code, then you can deactivate any device you no longer use. If you genuinely need more seats than your tier allows, additional licences are available on the pricing page.

Question 13

Can I transfer my license to a new device?

Accepted Answer

Yes, and you can do it yourself. Visit grammarindex.com/my-devices, enter your email and activation key, and we'll email a 6-digit verification code. Once in, you'll see every device currently activated against your licence and can deactivate the old one in a click. The new device can then activate normally with the same key.

Question 14

I lost my activation key — can I get it resent?

Accepted Answer

Yes. Visit grammarindex.com/my-devices, click the “Lost your key?” link at the bottom of step 1, and enter the email you used to purchase. We'll send the key to that address again. (For security we don't tell you whether or not the email is registered, but if it is, the email arrives within a minute or two — check spam if it doesn't appear.)

Question 15

What counts as a new device?

Accepted Answer

A “device” is a single OS install. The same hardware can count as a new device after some events — every one of these consumes a seat on your licence: reinstalling or reformatting Windows; resetting an iPhone or iPad to factory settings, or uninstalling every Grammar Index app; clearing your browser's site data, or switching browsers on the web edition; and buying a new computer or phone. If any of those is about to happen, visit grammarindex.com/my-devices first to deactivate the existing device — that frees up the seat for the fresh install.

Question 16

What happens if I'm offline for a long time?

Accepted Answer

Once activated, The Grammar Index apps work fully offline. The app rechecks your licence with our server occasionally when it has internet; if you've been offline for more than 30 days the app will ask you to reconnect to verify your licence. Activations that haven't checked in for 6+ months are automatically released back to your seat pool, so a phone you sold or a laptop you reformatted years ago doesn't permanently occupy a seat. If your licence is auto-released and you come back online, the app re-activates silently if a seat is available, or asks you to deactivate another device if not.

Question 17

Do you offer discounts for large institutions?

Accepted Answer

Yes! Volume pricing applies automatically: $2.00/seat at 10 seats, $1.75 at 30, $1.50 at 100, $1.25 at 500, $1.00 at 1,000. The Gift / Sponsorship tier drops to $0.75/seat for district-scale purchases of 10,000 seats. For orders above 1,000 seats outside the sponsorship tier, contact sales@grammarindex.com.

Question 18

What payment methods do you accept?

Accepted Answer

We accept all major credit and debit cards through our secure payment provider, Stripe.

Question 19

Is my payment information secure?

Accepted Answer

Absolutely. All payments are processed by Stripe, a PCI Level 1 certified payment processor. We never see or store your card details.
