A Free Device Mockup Generator for App Screenshots That's Actually Good
If you build apps, you've probably been here: the feature you've been iterating on is finally ready for the App Store or a promo post, and then you look at the screenshot:
A raw screenshot.
Messy background, wrong proportions. In the store it looks like a random screen grab, nothing like a "proper" product.
Ask someone to make framed mockups? Once or twice is fine, but every update means waiting for their schedule, explaining, revising... It takes ages, and after a while you feel bad about bothering them.
Do it yourself in Photoshop? Honestly, most developers aren't designers. Cutting out images, finding device templates, adjusting angles: that alone can eat half a day.
Framed screenshots aren't a huge deal, but they aren't a small one either. They directly shape users' first impression of your app, and that impression often sets the starting point for conversion.
Why framed screenshots deserve real attention
Some people think it's just showing off, but framed screenshots are a low-cost, high-return investment in looking professional.
Imagine a user swiping to your screenshots in the App Store and seeing a phone frame, the screen content and just the right shadow and reflection. The message is: "This is a team with taste who take things seriously. The product can be trusted."
With a raw screenshot, no matter how great your features are, the bare look subconsciously lowers users' trust in the product itself.
That's not superstition; it's real user experience.
Comparing the common options
| Option | Pros | Cons |
|---|---|---|
| Do it yourself in PS/Figma | Very flexible | High skill bar, time-consuming |
| Hire a designer | Great results | Slow and expensive |
| Third-party online tools | Quick and simple | Many charge or add watermarks |
Honestly, online tools are the best fit for indie developers and small teams: good enough, fast enough, and no need to rely on anyone.
The tool I'm recommending today is the one I use all the time: AppShot Maker's free device mockup tool.

Trying out AppShot Maker's device mockup tool
Core features
-
Completely free, nothing to download It runs in the browser, takes no local space, and never expires.
-
Lots of devices The full iPhone range (from SE to the latest), iPad, MacBook, Android phones... pretty much every mainstream device you need for app work.
-
Choice of colors and angles The same device comes in different colors and display angles, such as landscape or portrait and silver / space gray / gold finishes on different models.
-
Dead simple to use Just upload your screenshot and it's detected and framed automatically. Three steps:
- Pick a device → upload the screenshot → download
-
HD export The exported images are plenty sharp for App Store screenshots, blog and social media images, website showcases, Xiaohongshu (Little Red Book) posts and more.
My experience
What surprised me most was the automatic fitting.
Tools I'd used before either made me position the screenshot by hand or produced harsh edges. AppShot Maker is smarter here: once the screenshot is in, it rarely needs any adjustment, which saves a lot of hassle.
Also, device templates are updated promptly. New iPhone models are usually available quickly, with no long wait.
Real-world uses
Framed screenshots have a lot of uses:
- 📱 App Store / Google Play screenshots: look more professional and lift download conversion
- 📣 Promo images for WeChat articles or Xiaohongshu: content with context gets more attention
- 🌐 Product showcases on your website: visitors see at a glance how the app works
- 📊 Business materials: demo decks for investors and partners
- 📱 App store ASO: screenshots for more devices and sizes cover more keywords
Make it once, reuse it everywhere. Great value.
Final thoughts
Indie developers have limited energy. If a tool can do it, don't spend human hours on it.
I've been using AppShot Maker for a while now: stable, free and good enough. I've handed my app mockups over to it entirely.
If your app needs good-looking framed screenshots too, give it a try. It's free, there's no download or sign-up, and it works as soon as you open it.
