This type of logical puzzle was first seen in the Japan Puzzle Championship 2006 and is sometimes known as Doppelblock, or Smashed Sums. When played with pencil and paper, these puzzles can be hard work to solve. Sumaddle changes that by transforming the puzzles into interactive brain teasers that unfold before your eyes. Each puzzle has a unique solution. Finding the solution involves fitting the number combinations to the clues. The app makes it easy to view the possible combinations, you don’t need to do any sums in your head. Instead, you are able to focus on using logic to narrow down the combinations and find a fitting arrangement. The puzzles come in a range of sizes and difficulties, to suit all levels of skill and puzzling purposes. Choose a small puzzle to idle away a minute or two while waiting in a queue, or a big puzzle to give your brain some exercise during a coffee break! Some reasons why you will enjoy playing Sumaddle: • more than 150 puzzles are included for free • all puzzles can be solved with pure logic, no mental arithmetic required • the sophisticated built-in help can explain the logical reasoning at each step and also fix mistakes if you go wrong • the built-in help is completely free, use it as much as you like • works offline (great for long journeys) • a high standard of accessibility, including comprehensive support for VoiceOver • ad-free play - there are absolutely no ads!

Verdict
The clearest difference is ads: Sumaddle at none against Flow Fit's shown. Sumaddle also leads on review sentiment (95% vs 69%) and update cadence (every 3 weeks vs every 2 months). Flow Fit's advantage is ratings volume (6.7K vs 769) and iOS requirement (10.0 vs 17.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Flow Fit sells 4 one-off in-app purchases and Sumaddle sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for Flow Fit against 4.9 for Sumaddle. That said, the two scores are not equally well evidenced: Flow Fit has 6.7K ratings behind it against 769, so its average is the more settled of the two. Written reviews are what separate them: 69% of Flow Fit's written reviews are positive against 95% of Sumaddle's.
Flow Fit ships an update every 2 months, Sumaddle every 3 weeks. Both last shipped on November 3, 2026.
