Non vs Permutation Combination
Price, ratings, monetisation and update history for both apps, side by side โ with what reviewers say about each.
Non
This utility helps users create groups of people without duplicates. Input group sizes with hyphens for uneven numbers, and the app automatically generates groupings. It also allows checking for overlaps with previous groupings and can be set to avoid duplication.
- Continuous grouping without duplication
- Automatic grouping based on input
- Handles uneven group sizes
- Checks for overlap with new groupings
- Option to avoid duplication

Ideal for those who want to do continuous grouping without duplication. We will respond to the needs you want to group easily in various scenes. If you enter the number of people for each group(โป) and the name you want to group, it will be automatically grouped. โป If the number of people in the group is even, please enter only that number. (Example: If you want to group two people at a time, enter "2") If the number of people in the group is not even, please input each number by a hyphen. (Example: If you want to group 3 people, 2 people and 1 person, enter "3-2-1") Once you can leave a fixed grouping, you can check the overlap with the new grouping. Also, by setting "avoid duplication" ON, you can combine as much as possible to avoid duplication when new grouping is done.

"Permutation Combination Calculator" is an application that makes it easy to perform calculations for permutations and combinations commonly used in mathematics and statistics. By using this app, even those who are not good at mathematical calculations can easily perform calculations. The app is equipped with functions for performing permutation and combinatorial calculations. In permutation calculations, you can find the number of cases where r elements are selected from n elements. Combinatorial calculations, on the other hand, allow you to find the number of cases where r elements are selected from n elements, disregarding the order. In web-based examinations with strict time limits, reducing the time spent on calculation questions can free up time to answer other questions. By allocating your time appropriately and using the "Permutation Combination Calculator", you can take the web-based examinations efficiently and accurately.

Verdict
The clearest difference is ads: Non at none against Permutation Combination's shown. Non also leads on review sentiment (33% vs 0%) and monetization model (free vs ad-supported). Permutation Combination's advantage is update cadence (every 2 days vs every 2 months). On price, in-app purchases and device support there is nothing between them.
