This is a note app with an AI assistant (cat) that makes taking notes fun! We created this app for those who are looking for a note app that's a little more exciting than the standard one. It's designed for those who love to write and appreciate the beauty of text on their iPhone or iPad. It's a note app with a concept of enhancing the beauty of text on iPhone or iPad, so the decorations are kept to a minimum. Do you have a lot of messy notes? Our AI assistant can help you summarize them. Main features: - Pinch in/out (two-finger zoom) to adjust text size. It's incredibly intuitive! - Toggle ruled lines on/off to display them only as needed, without detracting from the beauty of your writing. - Chat with AI assistant. - AI assistant suggests title/summary/tags candidates based on the content of your note. Please note that this feature requires in-app purchases using ChatGPT. However, we offer a free trial, so give it a try! - Sync with iCloud. If you're signed in to iCloud, your notes will be automatically synced with your other iPhones or iPads. For example, you can jot down ideas on your iPhone while you're out and about, then continue writing on your iPad when you get home. Your notes are backed up to your private iCloud account, ensuring security and peace of mind. Even if you switch devices, the app will automatically restore your notes. - Apple Watch compatible. Displays the specified note and appends additional text input. - Widget. It's a unique feature that links the font size and display of the ruled line to the app! - Preview by long-pressing. - Tag. - Favorite. - Quick editing. Edit your notes with minimal effort. - Search for notes. Supports AND search and keeps a search history. - Sort notes in various orders. - Share notes.

These are advanced features for professional writers. - blank Web+. An extension for analyzing web pages and retrieving HTML and text. Please execute it from the Safari share menu. - Import notes from WriteCube. There are some things that our app cannot do. We do not have a folder organization feature, and you cannot add images, tables, or lists to your notes. You also cannot decorate your text, because we believe that the text itself should be the focus of our app. You cannot remove our AI cat assistant either. Lastly, please note that using the ChatGPT API will incur charges. We cover the cost of your free usage, but we would appreciate it if you could consider supporting us by paying for additional usage. Think of it as treating our AI cat to some snacks! With your support, we can continue to develop and improve our app. Thank you for reading until the end. Have a nice day!

Verdict
The clearest difference is rating: Calculator₊ at 4.7 against blank* note's 4.0. Calculator₊ also leads on ratings volume (1.7M vs 1) and chart position (#96 vs unranked). blank* note's advantage is review sentiment (100% vs 63%) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model 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
Both are free to download. Calculator₊ sells 12 in-app purchases, starting at $0.99 per month and blank* note sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
Calculator₊ holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Calculator₊ has 1.7M ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 63% of Calculator₊'s written reviews are positive against 100% of blank* note's, so the app with the better star average is not the one people write more warmly about.
Calculator₊ ships an update fortnightly, blank* note every 3 weeks. The most recent releases landed on October 18, 2026 and October 7, 2026 respectively.
