Need Enter button analog ### 4/5 — Super Useful - Some Very Annoying Hitches. PLEASE FIX THIS I BEG OF YOU *2025-11-17, version 2.1.8* This app is awesome to use in place of a scratch pad for doing any sort of math problem. I’m doing calculus and haven’t run into any equation that this app couldn’t write out for me to help solve. The only complaint I have - and it’s a big complaint - is that it is not at all easy to go in the middle of your equation to make edits. You tap to get the cursor somewhere and it goes nearby but not to it, for example, tapping on the denominator of a fraction usually puts the cursor on the numerator and there’s no way to edit the denominator without retyping the whole thing usually, and if you are editing a fraction or an exponent, the keyboard doesn’t give you the option to jump to a different line like it does when you’re first typing things out. If this was fixed, this would be the best app in the world for doing algebraic manipulation. ### 5/5 — Type setting *2025-11-01, version 2.1.8* The best app to properly typeset mathematics formulae. Textbook quality. And there’s really no other app that does it. ### 5/5 — スマホで使える数式エディタ *2025-02-02, version 2.1.8* スマホで手軽に数式が打てるエディタです。 latex等の知識が無くても、キーが用意されてるので簡単に打てます。 作った数式の写真も簡単に出力できるので、人に共有する時重宝します。 ちょっとフォルダの使いづらさを感じますが、それを差し置いてもかなりのメリットがあるので入れ得のアプリだと思います。 あと強いて言うならAndroid版も作ってくれたら嬉しいです。 ### 5/5 — Es muy intuitiva *2024-06-17, version 2.1.8* La aplicación es concisa y fluida. Muy buena ### 1/5 — Wasted money *2024-03-15, version 2.1.8* Complicated to use, buggy (like the return from superscript only works sometimes), copy & paste destroys formula, must be sent via test or email to get an image of it. ### 3/5 — Great app *2024-01-20, version 2.1.8* It’s good to practice but you can’t copy and paste them elsewhere ### 3/5 — It doesn’t really tell you anything… *2024-01-14, version 2.1.8* For my case I don’t know how to make a new line in the same equation, as it never tells you It has potential, but if they gave a little tutorial for some of the features, like how to make lines it would be a 4-5 star rating. Edit: I finally found out the multiple lines feature, but doesn’t elaborate much, which confused me, which is why I rate it a 3 now ### 5/5 — Great app *2024-01-08* Great app, you can write equations, formulas, save them, copy and paste them, I wish it was a proper keyboard but is a great tool anyways. ## Frequently asked questions about Nuten ### What does Nuten do?
