Liquify
Arms, chin, waistline — sorted in 30 seconds. An iOS app.
A photo editor that does one thing: nudge the one part of a photo you are not happy with. No sign-up, no ads, no subscription. Everything runs on your iPhone.
The problem it solves
You just took a photo you mostly like, but an arm looks heavier than you remember, or the angle gave you a second chin. You want to fix that one part and be done in half a minute.
Almost every photo app has a liquify tool, but it is buried in a long pipeline — sign up, watch an ad, three menus deep, and then pay every month. Liquify cuts that down to: open, pick a photo, adjust, save.
Two ways to work
Auto adjust (once a face is detected)
The app finds the face by itself and gives you five sliders:
- Slim face — narrow the face shape
- Slim chin — tighten the jawline
- Bigger eyes — enlarge the eyes
- Smaller nose — narrow the nose
- Smooth skin — even out skin while keeping edges
You never have to decide where to push or how hard. If no face is found, the app says so plainly.
Manual brush (body, clothes, background — anywhere)
Drag with a finger. Four modes:
- Push — move pixels in the direction of your finger
- Shrink — pull inward
- Grow — push outward
- Restore — gradually undo an area you painted
Brush size and strength each have a slider. At any point, hold "Original" to compare against the untouched photo and release to go back — the thing you need most when you have gone too far.
What it deliberately does not do
Knowing what a tool refuses to do matters as much as knowing what it does:
- No filters, no colour grading, no styles
- No background removal, no stickers, no text
- No skin whitening, no face swap, no AI generation
- Not a full photo editor. If you want a complete retouching workflow, this is the wrong app — use Lightroom or Photoshop
Privacy
Your photos never leave your device. The editing is done by the iPhone's own graphics chip, and no image data is transmitted at any point. It works in airplane mode.
The app does not ask for photo library access. It uses the system photo picker and only ever receives the single photo you chose. Even if it wanted to read your other photos, it has no technical means of doing so. Saving uses the "Add Photos Only" permission and nothing else.
From version 1.4, the app reports anonymous usage data — which features were opened — so I can decide what to build next. You can turn it off in Settings, and once it is off nothing is sent. Everything that does get sent is listed, item by item, in the privacy policy.
Price
One payment. Not a subscription. No auto-renewal.
The free tier exports two photos a day with no other limits — no watermark, no restricted brushes or sliders. Unlocking removes the daily limit and includes future updates. The actual price is shown in your region's App Store.
Export
Full original resolution, no recompression, no watermark. Capture date and camera information are preserved.
Who it is for
- People who want to quickly adjust one part of their own photo
- People who do not want a monthly fee for something they use occasionally
- People who do not want their photos uploaded to anyone's server
- People who find existing photo apps too complicated to relearn every time
Who it is not for
- Anyone needing a full retouching workflow (grading, masking, compositing)
- Anyone who wants filters and stylised looks
- Android users — iOS only
- iPad users — it installs, but the layout is designed for iPhone
Requirements
iPhone, iOS 17.0 or later. Available in English, 繁體中文, 日本語 and 한국어.
Questions people ask
- Are my photos uploaded anywhere?
- No. Everything runs on your iPhone. It works in airplane mode.
- Do I need an account?
- No. There is no account system.
- Is it a subscription?
- No. One payment, no auto-renewal.
- Does the free version add a watermark?
- No. The only limit is two exports per day. Quality and features are identical.
- Can it edit bodies, or only faces?
- Both. The automatic sliders are for faces; the manual brush works anywhere in the photo, including arms, waistline and clothing.
- What if I overdo it?
- There is undo and redo, and you can hold "Original" to compare at any time. Your original photo is never overwritten.
- Is there an Android version?

推肉肉小工具
手臂、雙下巴、腰線，三十秒調好。iOS App。
一個只做一件事的修圖 App：微調照片裡你不滿意的那一小塊。 沒有註冊、沒有廣告、沒有訂閱。所有運算在你的 iPhone 上完成。
它解決什麼問題
你剛拍了一張還不錯的照片，但手臂看起來比記憶中粗一點，或者角度讓下巴多了一層。 你想調的就是那一小塊，三十秒內結束。
現有的修圖 App 幾乎都有液化功能，但它被包在冗長的流程裡 —— 要註冊、要看廣告、 選單三層深、最後還要你每個月付錢。推肉肉小工具把那條路砍到只剩： 開啟 → 選照片 → 調整 → 存檔。
兩種做法
自動調整（偵測到臉之後）
App 會自動找到五官，然後給你五條滑桿，拉到剛好為止：
- 小臉 —— 收窄臉部輪廓
- 瘦下巴 —— 收下顎線條
- 大眼 —— 放大雙眼
- 縮鼻 —— 縮小鼻翼
- 磨皮 —— 讓膚質平滑，但保留輪廓
不用自己判斷該推哪裡、推多少。偵測不到臉時這一頁會明白告訴你。
手動筆刷（身體、衣服、背景都可以）
手指直接塗抹，四種模式：
- 推移 —— 把像素往手指移動的方向推
- 縮小 —— 朝中心收縮
- 放大 —— 往外擴張
- 還原 —— 把塗過的地方慢慢還原
筆刷大小與強度各有滑桿。任何時候按住「原圖」就能跟原始照片對照， 放開回到編輯後的版本 —— 修過頭的時候這個最有用。
它刻意不做的事
知道一個工具不做什麼，跟知道它做什麼一樣重要：
- 沒有濾鏡，不調色、不加風格
- 沒有去背、沒有貼圖、沒有文字
- 沒有美白、沒有換臉、沒有 AI 生成
- 不是全功能修圖 App。如果你要的是完整的後製流程， 這個不適合你 —— 去用 Lightroom 或 Photoshop
隱私
照片不會離開你的裝置。修圖運算使用 iPhone 本身的繪圖晶片完成， 過程中沒有任何影像資料被傳送出去。開飛航模式也修得動。
這個 App 沒有要求相簿讀取權限。它使用 iOS 系統的照片選取器， 只拿得到你主動選的那一張。即使它想讀你的其他照片，技術上也做不到。 存檔時只用「加入照片」這一項權限。
從 1.4 版起，App 會回報一份匿名的使用統計（哪些功能被打開過）， 用來決定接下來該做什麼。可以在設定裡關掉，關掉之後完全不送。 送出的內容逐條列在隱私權政策裡。
價格
一次付清，不是訂閱，不會自動續訂。
免費版每天可以匯出兩張，功能完全不打折 —— 沒有浮水印，不限制筆刷或滑桿。 解鎖之後匯出不限次數，未來版本的更新一併包含。 實際價格依你所在地區顯示，以 App Store 為準。
匯出
以原始解析度輸出，不壓縮、不加浮水印。拍攝時間與相機資訊一併保留。
誰適合用
- 想快速微調自己照片裡某一小塊的人
- 不想為了一個偶爾用的功能付月費的人
- 不想讓自己的照片被上傳到任何伺服器的人
- 覺得現有修圖 App 太複雜、每次都要重新找功能在哪的人
誰不適合
- 需要完整後製流程（調色、去背、合成）的人
- 想要濾鏡與風格化效果的人
- Android 使用者 —— 目前只有 iOS
- iPad 使用者 —— 可以安裝，但目前是 iPhone 版面，沒有針對 iPad 設計
系統需求
iPhone，iOS 17.0 以上。支援繁體中文、English、日本語、한국어。

- 可以調身體嗎，還是只有臉？
