E ficou ótimo! Então vim mudar minha avaliação… ### 5/5 — New updates made app awesome but stability issue *2026-10-24* You new update has really brought many new features and its really helpful and futuristic. But recent update had made app very sluggish, hanging and even it gets crash sometimes. Although with every updates things are improving, still please focus on improving app stability 1st as its hampering our work. Thanks for your effort. **Developer response:** Hello! Thanks for your feedback! Best regards, Notes Writer Team ### 1/5 — Whyy *2026-10-23* The new actualization doesn’t have an option to make the brush smaller, it has sizes but they dont match to the size I had before the update, and now the text has to be gigantic in comparison to what i had, also if i try with another brush that reselmbles the size i want it looks pixelated and kicks me out of the app ### 2/5 — This was a 5 star app before the new UI update *2026-10-16, version 27.1.4* The new UI/UX update is horrendous!! This used to be a 5 star app for me. Very simple and classic. Now it's too buggy and futuristic. I can't erase handwriting from documents that I've copied anymore. The undo button, opens another undo (or redo) button every single time. I used to be able to just continuously press one undo button times. Now I have to press two undo buttons in two different places for every pen stroke I want to undo. Apple pencil is now suddenly laggy. It's so trippy to write a word and not have a letter show up on the screen until you've finished the next 1-2 letters. I hate when apps ruin a perfectly good thing. ### 1/5 — 悪刷新 *2026-10-08* UIを大幅に刷新！とのことですが、今まで右開き左開き両方に対応していたのが、スクロールしかできなくなりました。 これができることに価値があってお金を払ったのに残念です。 配置なども変わりすぎて本当に使い物にならなくなりましたし、今までお世話になりました。 ### 2/5 — Lack of Support *2026-09-15, version 26.5.0* UPDATE July 2026 - not only no support, for ages now: Issues: BACKUPS If you want to backup your notes, you can not just backup as you can with most notes app. You need to abandon your note organization...because you would need to move notes to a special backup folder. REMOTE STORAGE No way to keep notes on a WebDAV - so your notes consume a stack of room on your phone . Original: Contacted company 3 times over the past three months the - zero reply. ### 4/5 — Add a Tape feature *2026-09-08, version 26.5.0* This app is not that bad, but it would be better if they add a tape feature, just like Goodnotes and other apps for studying purposes. ### 1/5 — Не загружай, не удалить *2026-08-27* Не дает удалить и не работает ### 5/5 — Excelente *2026-08-24, version 26.5.0* Muy útil ### 5/5 — Fantastic !! *2026-07-25, version 26.5.0* Damn good ## Frequently asked questions about Notes Writer ### What does Notes Writer do?
