### 2/5 — Getting rid of pages

*2026-08-11, version 3.45.0*

I loved the app, after I bought premium many of the page options got paywalled and just completely disappeared. I wanted to use them. 😫😢

### 3/5 — Stickers

*2026-08-09, version 3.45.0*

Apparently, you now have to pay for stickers, even if you have premium? Stickers used to be included a month ago? I’ve been using kilonotes for over two years now and have loved it, but this is seriously affecting my experience.

### 5/5 — Best note taking App ever

*2026-08-07*

It’s been over a year that I downloaded this app and let me tell you is the best app ever because not only help me take notes easily but also I get a lot of benefits from the memberships and new designs that I can add or create a journal with also they have a lot of stickers in it. I love it so far. The only thing that I would like them to add is when you scribble with a pencil, it will be awesome that they can’t erase it as well without using the box text or clicking on it the whole time so it’s better to scribble down to delete it. It will make them have more success on it.

**Developer response:** Your positive feedback gives us more motivation. Thank you very much for your positive review.

### 5/5 — Literally the best

*2026-08-06, version 3.44.1*

Just finished my first quarter of nursing with this app and it’s truly a lifesaver. 
-Recording feature 
-Customizable pens/pencils/fonts/paper/notebook covers/you name it
-Can upload your PDFs or pictures and write on them (SO helpful for labeling models)
- If you minimize your photos app (on iPad), you can just drag whatever picture and it will automatically make a sticker and place it in your notebook (great for book diagrams that are directly embedded into your notes)
-So many free and cute stickers!
-ONE TIME PAYMENT for unlimited premium access. In this economy? SENSATIONAL. Goodnotes and most other apps have a stupid monthly/yearly subscription but not Kilonotes. Pay once, get it all.
-Actually there are some things you have to individually purchase but those are like, special stickers or templates. Almost everything else is free or included with the lifetime membership though.

Overall, 100/10.
Only thing I would ask is for the folders to be customizable as well. Fingers crossed it will be included in an update soon 🤞🏼

### 3/5 — 광고가 너무 많아짐

*2026-08-04*

안녕하세요? 킬로노트 잘 쓰고 있는 학생입니다. 킬로노트는 애플팬슬 인식도 잘 되고 AI 기능도 있어 너무 편리하고 좋습니다. 그런데 최근 들어 광고가 심하게 많아진 듯 합니다. 과연 광고를 보는 사람들이 공부와 필기에 집중을 할 수 있을까 싶은데요..	그리고 굳이 하나만 더 말하자면 꼭 애플팬슬이나 	블루투스 펜으로만 그릴 수 있는 게 편리할 때도 있지만, 불편할 땐 매우 불편합니다. 한 번은 애플팬슬의 베터리가 없어 손으로 간단히 적으려다 안되서 당황한 적도 있습니다. 만약 이 두 부분을 고쳐주신다면 킬로노트는 굿노트 뺨 치는 필기 앱이 될 것으로 기대 중입니다.

### 1/5 — Not free…

*2026-08-02, version 3.44.1*

I have been looking for a free note taking app and this one looked particularly hopeful looking at the reviews in the App Store and online, however this is yet another app that has a hidden paywall; *after* you download the app. In order to use this app for any more that 5 notes you must pay. The search for a free note-taking app continues…

### 5/5 — So far, LOVE IT!

*2026-07-29, version 3.44.1*

Ive spent 2 days on this app and it’s incredibly easy to use, the second i downloaded it I could start writing! It has aesethic free themes which i love because it gives me motivation to write,if you love pastels and cute stuff and want a free, cozy notes app, THIS IS FOR YOU!

### 5/5 — No ICloud Sync

*2026-07-27, version 3.44.1*

Favorite notes app by a mile EXCEPT.. I really wish I could have iCloud sync to different devices as I normally use on iPad but sometimes it’s not accessible!

### 5/5 — A little tricky, but worth it all.

*2026-07-22, version 3.44.0*

It’s a really good app, a little complex and intricate, but it does everything you need to. it’s perfect, literally.

### 1/5 — Device Sync & Improve Hyperlinks

*2026-07-10, version 3.43.1*

The biggest problem is hyperlink support. When duplicating pages in digital planners, internal links break, and external links are unreliable. This makes the app much less useful for planner users.
Another major issue is the lack of device sync. If I update my planner on my iPad, I can't access the latest version on my phone unless I manually export and download it every time. That's incredibly inconvenient.
Kilonote has amazing potential, but these essential features have been ignored for far too long despite repeated feedback from loyal users.
