### 5/5 — 修修bug

*2026-08-04*

在此软件里裁剪图片，当时是正常的，但到了下一次点开的时候，被裁减过的图片就会回到未被裁减的整张图片，同时被横向或纵向拉伸/压缩成裁剪后的长宽比，连再次裁剪都做不到

### 1/5 — 体验很差

*2026-07-23*

经常整个文件夹图片都消失掉，严重影响体验可以快点修一下这个bug吗

### 3/5 — Ничего хорошего, дешевое и минимум функций за эту цену есть.

*2026-03-15*

Нельзя организовать изображения красиво, так как нет направляющих. Кнопка Sort для меня бесполезна, потому что там только один вариант, а не несколько сеток, чтобы выбрать наиболее подходящую. А если добавить ещё	 пару изображений то кнопка Sort перетасует всё ещё раз совершенно по другому. И то как приложение выстраивает изображение никак не привязано к моей задумке. Мне нужно чтобы в центре было одно ключевое изображение, а остальные вокруг, а кнопка Sort никак это не понимает. Если рисовать карандашом линии очень корявые. Чтобы приложение на iPad так плохо работало с карандашом - это «выдающийся» результат. Для iPad качество просто неприемлемое. Я не ставлю одну звезду только потому что дешевое, если людям хватает просто доски за 100 руб. куда можно накидать несколько изображений, пускай пользуются и радуются.

### 4/5 — Love this app

*2026-02-18*

I love this app so much, but now there is a problem - some of my boards become empty, the folder image shows pictures, but when you go into it - there’s nothing there😭

### 4/5 — Easy to use

*2026-01-27, version 1.0.9*

Love this app use on daily but wish there was an export feature to return the image back into the gallery.

### 4/5 — 希望出图片复制功能和标尺功能

*2026-01-12*

虽然再倒入一次也可以，但是还是麻烦，希望直接有个按钮复制，并且希望可以有吸附对齐功能，自动排序不一定是自己希望的排列，挪动时候又不能完全对齐，标记除了三个大小选项，还希望加入滑块调整笔刷大小功能

### 5/5 — 希望可以增加多图框选缩放大小的功能！

*2025-11-23*

特别好的软件！！但是不同批次间导入的图片大小不一样，一张一张调整大小好麻烦😖😖

### 2/5 — A gesture!!!

*2025-11-05*

The gesture is difficult to use, and it is depressing to require a three-finger swipe to start over.

### 4/5 — Almost perfect!

*2025-04-28, version 1.0.9*

Simple and it works! Great for storing reference pics for art projects. And it will allow you to mirror images if needed. The one thing I’d change if I could would be to have the option to sync folders to icloud. I’d love to be able to sync backup these folders. Even just an option to download them would be great. But thanks for making a reliable app that fills a need!

### 5/5 — 有些需要改进的点

*2025-03-06*

1. 多张图片可以一起缩放大小 2. 插入的图片位置希望能显示在当前画布所在区域，而不是固定在某个位置，方便查找和手动排版 3. 多一个在锁定图片的情况下能移动画布的功能 4. 可以复制多张图片，方便重新调整图集 5. 导出功能 6. 图片或者画布旋转  希望开发者能看到QAQ 放很多图片还不会闪退真的很喜欢了！希望越来越好 比心❤️
