Very good app. Please include a highlight option to copy and paste, so it can be directly transferred to MS Word. Also, symbols like +, -, *, / , e.t.c, to get should be able to be inputed to know how many places a sign can be in a combination. E.g A+B-C and A-B+C and so on. Also, numbers like 10 and above are splited as 1 and 0. Lastly, once the letters exceed z, signs should be inputed like π, £, e.t.c. I really love this app and appreciate your team!

5 stars because I want to support this app but please 🥺 add a search 🔍 feature that will highlight whatever I search for exactly how it does on Google Chrome. Then I would buy pro. I feel this is essential when dealing with so many combinations or permutations and I just want to quickly get to the section that interests me. Thank you!

This app is exact what I need. There is complete concept that I need to implement. One thing that I missed that user can put only single alphabet not special character and multiple character.

While I appreciate the effort, it does not show part permutations without repeats. Who cares that you can show the same letters in many repetitive ways? IE with "banana" you can show aa in 6 different ways! So what? And there's no choice. Please rectify to make it more interesting and useful. Anagrams show different combinations but only using all the letters. Why can't anybody get it right?

Can't copy combinations! Add copy feature to copy all combinations
