Quick Proto

This free sketching app lets you do quick-and-dirty prototyping to try out (and share) user-interface ideas.

- Sketch a series of screens using your finger or a stylus.


- Link them together with hotspots.


- Hit "Play" and try out (or demo) your rough UI.


- Share your prototype as clickable HTML by email, Dropbox, etc.*

The goal of Quick Proto is to let you draw rough ideas as fast as possible
- sketch, link, share, done.

Works on all screen sizes (phone, small tablets, big tablets). Better with a stylus, particularly the Samsung Note series.

This app is FREE and has NO ADS. I hope you find it a useful addition to your design toolkit. Feedback is very welcome; let me know how I can improve it to suit your workflow.

Permissions: Photo/media/files (external storage)
- This is needed for sharing prototypes (see below).


* Sharing a prototype requires an SD card. Most recent devices include either an SD card slot or a "virtual" SD card (e.g. Samsung S3, Nexus 7, etc.), so this is probably only an issue on older Android devices.

It does what it says. Install it and start prototyping. Best part, one can create links. The only 2 things I felt it needed was the functionality to create geometric shapes and canvas size adjustment. That is why I have 4 stars, else it beats other tools.

just started using the app this week and its a great ui sketcher. Im a noob to ui design and found this is simple and process is sweetly streamlined. functionality beats alot of desktop ui builders which are so time consuming and complex to add elements. drawing solves layout nightmares. the app has been kept lite, which is brilliant. thanks also for no ads.

Simple, and does what it says. I wish that sharing handled a bit differently. If this was a paid app and had a limited number of enhancements it would beat every commercial prototyping offering on Android that I have tried.

Are you kidding me??! THIS IS PERFECT! Honestly my hopes were quite low but I was surprised by the ease of use and how easy it is to produce a sharable HTML lo-fi prototype. I love that it doesn't lock you into and platform.

Can you give a option to insert image rather with drawing board . As i made good ui in other vector app and need your image linking system to work. Then it won't be dirty any more. It is a very good app, love it 😊

Super nice and eco-friendly hehe, made me a nice little sketch for less than a day. 20 pages and 60 interactions. Really nice for quick on the go ideas!!!

Simple and effective. As an aspiring ux/ui designer, this is exactly what I need to begin creating low fidelity wireframes. Excellent app!

Noa. M. Mar 23, 2020     

Just as simple as I had hoped! Perfect for quickly getting a rough sketch of an app or website wired together with links from one page to another.

Simple, powerful, easy-to-use app for brainstorming ideas and flows. Pen support is awesome for on the go design and eureka moments!

Simplicity wins over everything else. Please add a few more simple options: Add geometric shapes. Add text tool. Import image & resize it to fit

Ira. S. Jun 17, 2020     

I haven't tried exporting or sharing yet, but it's very helpful. doesn't get in the way of thinking with cumbersome tools.

Kun. J. Jul 6, 2020     

Very easy to use. Question - after I have shared the wire frame via email and extracted the folder with html and png files, how do I run them on my PC. Do I need a software to run these files together as a prototype?

Very helpful for quick quick prototyping. Would love to see line and box tools to make drawings cleaner.

Smi. C. Aug 14, 2020     

Wow. I really2 love this. As an experienced software developer, I had tried many tools. This is super simple and super easy to use.

Cyr. I. Apr 22, 2022

Rob. E. Sep 21, 2020

Would be nice to have an endless white page where u can pinch-zoom in and out to have a bigger screen.

Gid. A. May 24, 2020     

Great app, just what I wanted, one suggestion would be adding the ability to input text. Thanks for the app

Tim. B. Jan 17, 2021     

Great tool no frills tool to get a feel for a rough design. (if you can write so you can read it afterwards!)

Dan. Z. Jan 29, 2020     

This is exactly what I wanted to fast prototype board games. And it's freeware, so, amazing.

Bah. S. May 28, 2022     

Why no image import? I got ready images from photoshop but no way to import

Bar. C. Nov 9, 2021     

Great prototyping app! The possibility to add a picture as a background would make it a 5 star app ;)

Man. V. Dec 7, 2019     

Just Right. It helps me get those screen ideas that come to me when on the bus or train . It's a great app.
