Уникальное по своей гибкости благодаря тому что много кривых, а не линейные ползунки. Жаль что вы прекратили разработку. Продолжайте! Можно добавить ИИ выделение объектов, кисть усовершенствовать потому что сейчас нет кнопок Undo, Redo… Интерфейс чуть-чуть, обновить, потому что сейчас Home Line мешает. Пожалуйста продолжайте разработку, сделайте версию 2.0! Very good application. Unique in its flexibility due to the fact that there are many curves, not linear sliders. It's a pity that you stopped the development. Keep going! You can add AI object selection, AI objects remove, improve the brush because there are no Undo, Redo buttons now... The interface waiting for update, because now Home Line interferes. Please continue the development! Release version 2.0! ### 5/5 — Best Photo editing app on my IPad Pro *2025-11-13, version 3.1.1* This is truly a fantastic photo editing tool, I use it constantly and I’am a 30 year user of Photoshop, but now my go to is Affinity Photo for desktop editing. But always MaxCurve for my iPad as I said it’s fantastic ### 4/5 — Приложение ТОП, пользуюсь давно и в целом все нравится *2025-02-26* Функционал отличный, обработка фото (с камеры, не с телефона) удобная, инструментов мне хватает полностью. Да и не прям всем пользуюсь. Тут все отлично. Но есть нюанс. Максимальный размер ЭКСПОРТА фото 4096х2732, то есть 11Mpix, не смотря на то, что в настройках экспорта указан пункт «по снимку» а снимок сделан в разрешении 7952х5304, соответственно 42Mpix. ### 3/5 — Нет обновлений *2025-01-11* Нет обновлений ### 5/5 — please update!!! *2024-06-15* 오래 쓰고싶다!!!!! ### 2/5 — Poor functionality *2024-04-26, version 3.1.1* This app used to be great, possibly since an update they make it hard to save photos back to IPhoto, edited, photos, disappearing? Looking for a replacement app… ### 5/5 — Best Photo editing app on my IPad Pro *2024-03-30, version 3.1.1* This is truly a fantastic photo editing tool, I use it constantly and I’am a 30 year user of Photoshop, but now my go to is Affinity Photo for desktop editing. But always MaxCurve for my iPad as I said it’s fantastic ### 5/5 — Schön *2024-02-06* +++++++++ kein abo ## Frequently asked questions about MaxCurve ### What does MaxCurve do?
