Features: > 6 game modes: - Addition - Subtraction - Random (both addition and subtraction questions in the same test) - Fill the gaps (you get given the answer and part of the question and have to complete the question - i.e. 3+?=9) - Tricky questions (the questions you got wrong previously) - Money (add the values of various coins together - choose from either British Pounds & Pence, Euros or US Dollars & Cents) > 4 difficulty levels for each game mode mean this app is suitable for 4 year olds just starting out with adding as well as 10 or 11 year olds who need to practise more complex maths work: - Beginner (answers between 1 and 10) - Medium (answers between 1 and 20) - Hard (answers between 20 and 100) - Very Hard (answers between 100 and 1000) > Difficulty levels can be switched off or on, on a per-child basis, so older children can't just earn lots of rewards for answering beginner-level questions and beginners won't get demoralised by being shown more complex sums. > "Squeeble-cart" mini game gives children a reward for doing well in their maths questions. For each question they get right, they win one turn on the game.

These can be traded for different cars to use in the squeeble-cart game. There are 40 cars to collect, each with different stats. > There are 24 Squeebles to rescue from the Maths Monster, each with their own personality and fact sheet which tells you all about them. > Unlimited children can be registered with the game, meaning this app is suitable for classroom use as well as for home use. > Passcode-protected stats area lets parents / teachers see how well each child is doing. > No in-app purchases, adverts or web links of any kind. > US and UK English options so the Maths Monster becomes the Math Monster etc. As always, if you need any further information or help, please get in touch by e-mailing info@keystagefun.co.uk

Verdict
The clearest difference is price: Readability at Free against Squeebles Add & Subtract's $2.99. Readability also leads on rating (4.6 vs 3.7) and update cadence (fortnightly vs every 7 months). Squeebles Add & Subtract's advantage is review sentiment (100% vs 56%) and in-app purchases (none vs 2). On ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Readability is free to download; Squeebles Add & Subtract costs $2.99 up front. Readability sells 2 in-app purchases, starting at $19.99 per month. Squeebles Add & Subtract asks for nothing beyond the download.
Readability holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Readability has 25K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Squeebles Add & Subtract's written reviews are positive against 56% of Readability's, so the app with the better star average is not the one people write more warmly about.
Squeebles Add & Subtract ships an update every 7 months, Readability fortnightly. The most recent releases landed on October 26, 2026 and October 30, 2026 respectively.
