Both drill the same twelve tables. The one that works is the one your child opens without being asked.
We make Multiply.Cards, so we're not a neutral party and you shouldn't read us as one. We've tried to write the comparison we'd have wanted when we were choosing — including the parts where theirs is the better buy.
Multiply.Cards
An aquarium they build
Answer questions, earn coins, spend them on fish, plants and decorations for an aquarium that's theirs. The reward is something they keep and come back to look after — quieter, less about speed, and it suits children who lock up against a clock.
A fish needs no translation. Every child on earth knows what one is, whatever language they answer in — and one tap puts the aquarium full screen, so it can sit on the classroom screen all afternoon.
Coins are earned by practising — nothing in the child's app costs moneyTimes Tables Rock Stars
A rock star they become
Race the clock, earn coins, spend them kitting out a rock-star character. The reward is status and a faster time than yesterday — competitive by design, and for a great many children that is exactly the thing that gets them practising.
It assumes the child wants to be a rock star. A brilliant hook where that idea already means something; less of one where it doesn't.
Speed, streaks and a character to show off
Languages and voices
Translation changes the words on a page. It can't change the voice a child hears.

Ask them
Their site publishes no language or voice list, and every voice we came across was English — but we have not confirmed that with them, so we're not going to state it as a fact. Ask them, and tell us if we've got it wrong.

Practising as a whole class

Practise mode, on the class screen
Step through a table one card at a time while the voice says it and the class says it back. With 22 voices across 15 languages, children are copying a clear model — pronunciation practice as much as tables practice, which matters where English is a second language. The same screen works alone on a tablet.
Times Tables Rock Stars
Worksheets and video chants
Printable drill sheets for paper practice, and a set of video and audio chants for skip counting that a teacher can play to the room. As far as we could find, the on-screen activities are built for a child playing alone rather than a teacher leading a class through a table. Ask them.

Find yourself below. Two of these aren't us.
A class that doesn't all think in English
Welsh-medium schools, Gaelscoileanna, EAL pupils. Small communities get localised last — Welsh and Irish are in every plan here, including the free one.
Multiply.Cards
A child who freezes on a timer
Practice without a countdown breathing down their neck, and a reward you tend rather than a score you defend.
Multiply.Cards
A child who thrives on beating a time
If competition is the fuel, theirs has been built around it for years and the children know the format.

A big school that wants no caps

Run both for a half-term with two parallel classes and see which one the children keep choosing.

What children play for
Coins for an aquarium they build and keep. Coins come from practising, and nothing in the child's app costs money.
Coins for a rock-star character, played against the clock.
On the classroom screen
Full-screen aquarium. One tap turns an aquarium into a live display for the class screen or a monitor in the corner — and children will work to get theirs up there.
Not verified — ask them
Practising out loud together
Practise mode walks a table one card at a time, with the voice reading each one aloud — on the class screen for everyone, or alone on a tablet. Children hear the words as well as see the numbers, which matters when English is a second language.
Printable worksheets and video chants for the room. We could find no teacher-led slideshow — their screens appear to be built for a child playing alone. Ask them.
The voice a child hears
22 spoken voices across 15 languages, including Welsh and Irish, with English in US, UK, Indian and Australian accents. Free on every plan.
No language or voice list is published, and every voice we came across was English. We haven't confirmed this with them, so we don't state it as fact. Page text can be machine-translated by a browser; that isn't the same thing.
Getting a child signed in
A printed card with a QR code, made in the app. Build a class, print the cards, done — no IT setup and no integration. The child scans and is playing; the code, like boat.5899, carries no name and no email. Send the card home and practice carries on there.
Printed cards too, with a username and a password or three-symbol picture PIN for the child to type in. QR sign-in appears to need a school-wide SSO integration set up by IT rather than being built in. Ask them.
Finding out how they're doing
Ask in plain English — "How is Year 4 doing on their 7s?" — and get it back written up. Daily briefings arrive unprompted.

The short version, if you've read this far.
