Inaccurate

I paid for the year and have yet to have a measurement accurate. I asked for a refund but heard nothing back

Response from developer

Hi, thank you for the feedback, and I'm sorry for the frustration this has caused. First — please check your spam folder. We reply within 24 hours, and we already responded to your refund request yesterday, about 5 hours after you emailed us. Our reply was very likely filtered there. On the refund itself: we sent clear step-by-step instructions on how to request one. Refunds are processed by Apple, not by us, so we're unable to issue it directly — but we're glad to walk you through Apple's process. On accuracy: our app is designed to reach 5–15mm accuracy when the phone is held straight, so following the in-app guides makes a real difference. We're also about to release a new version that achieves ~5mm accuracy and stays industry-leading even when the phone is tilted. We're proactive in every way about helping users get accurate measurements and resolve refunds. Please do check your spam folder, as a filtered reply is the most likely reason you haven't heard from us — and feel free to reply to that email anytime.

Worked great… for a while

I downloaded this app with the hopes it would speed up posting clothes on eBay and other platforms. It worked great for about a week, but recently it has stopped reading tags. I’ve downloaded a new version and tried everything. Forget getting help because it just isn’t intuitive. Disappointed.

Response from developer

Hi, thank you for giving the app a real try, and I'm sorry the tag scanning let you down. The tag reader is working normally on our end, so the most likely cause is an internet connection issue — the scanner needs an active connection to read and process labels, and it can quietly fail if your signal drops or Wi-Fi is unstable. Please try again on a strong connection; in most cases that resolves it right away. If it still doesn't work after that, email us directly at support@sizeai.co — we reply within 24 hours and can look into your account and get you sorted quickly. Getting help should be easy, and if it felt like it wasn't, that's on us to fix. We're also improving the scanner and its guidance in our next release to make issues like this clearer and easier to solve. We'd really like the chance to turn this around for you.

My whole team uses it now

Started using it myself then showed my partner and now our 3 employees use it too. We do about ~200 items a week, plus the ghost mannequin shots keep everything looking consistent which was not the case before.

Way faster than my old process

I used to lay everything out, measure with a tape, take photos, then edit backgrounds in a separate app. Now, I just scan and it does all of it. I'm impressed! The mannequin shots are a nice bonus I didn't expect, went from maybe 12 listings a night to like 30ish

the mannequin photos tho

ok I was not expecting the ghost mannequin thing to actually look good but it does?? I used to pay someone on fiverr to edit my photos and honestly these look just as clean. saves me like $80 a week easy. The only complaint is I wish I found this sooner lol

Won’t measure

It won’t measure your listings unless it’s not wrinkled

Inaccurate measurements

I’m not canceling yet because the app is well on some measurements. However, I’m struggling to get accurate pit to pit measurements on sweaters, jackets, button ups, clothing, with sleeves. The sleeve seemed to interfere with the AI detection, making this measurement difficult to capture consistently.

Response from developer

Hi Vassi1972, Thanks for the feedback and for continuing to give Size AI a try. Pit-to-pit measurements can sometimes be tricky, especially on garments with long or wide sleeves. Size AI can only measure what the camera clearly sees, so if sleeves are folded, overlapping, or covering the underarm area, the AI may not detect the pit correctly and has to guess where the edge of the pit is. To improve accuracy, try spreading the sleeves so the underarm area is fully visible. Taking the photo from a bit farther away, or using Landscape mode, can also help ensure the entire garment fits clearly within the frame. We’re continuously improving detection for long-sleeve garments, and feedback like yours really helps. We’re also working on adding more examples and guidance to show how to capture accurate measurements across different garment types. If you’d like, feel free to share an example with us at support@sizeai.co. We’re happy to take a look and provide suggestions. Thanks for helping us make Size AI better.

great app for beginners

I’m new to reselling and this app made the measuring part so much less scary. The capture guide walks you through everything. Once you get the hang of the angle and lighting, the results are very accurate.

Response from developer

Hi Carlisle_Knollf, Thanks so much for the kind words and welcome to the world of reselling. We built Size AI to make measurements simple and stress-free, especially for beginners, so it’s great to hear the capture guide helped you get comfortable with the process. You’re absolutely right, once the angle and lighting are dialed in, the results become very consistent. Wishing you lots of success with your business, and thanks for using Size AI!

Export Feature Is Perfect

I love that I can export the measurement image in one tap. It puts everything in a clean format that looks good on every marketplace. No extra editing needed.

Response from developer

Thanks so much for the great feedback! We’re really glad you’re enjoying the one-tap export. Making sure measurement images look clean, consistent, and marketplace-ready was a big priority for us, so it’s awesome to hear that it’s saving you extra editing time. Appreciate you taking the time to leave a review!

Helpful For High Volume Sellers

My partner and I run a small warehouse and we process hundreds of pieces a week. Size AI has helped us standardize everything. The measurement images look uniform and professional across the whole catalog.

Response from developer

Thank you for sharing this! It’s great to hear that Size AI is helping you standardize measurements across a high-volume workflow. Consistency and speed are exactly what we aim for, especially for sellers handling large catalogs. We really appreciate the trust and the thoughtful review.

If You Sell Clothes, Download This

I’ve been reselling for years and this is hands down the best measurement tool. Background removal, model photos, tag reading, fast LiDAR measurements… it’s honestly crazy how much this app does. And it does it well.

Response from developer

Wow, thank you for the kind words! We’re thrilled that you’re getting value from so many features, from LiDAR measurements to background removal and tag reading. Hearing that experienced resellers consider this their go-to tool truly means a lot to us. Thanks for being part of the Size AI community!

Crazy Fast Measuring

Honestly shocked at how fast it measures. It takes less than a second on my phone. I list a lot of inventory and this has cut my workload down massively. My whole workflow feels smoother.

Response from developer

Thanks for the awesome review! Speed is a huge focus for us, so it’s great to hear that the measurements feel instant and that it’s cutting down your workload. Making inventory listing faster and smoother is exactly what Size AI was built for. Really appreciate you sharing your experience!

Makes Me Look Like I Have a Studio

I don’t have a fancy photo setup at home but the background removal plus TrueShape makes it look like I do. Buyers actually cọmpliment my photos now which has never happened before. I’m listing faster and selling faster. Great app.

Response from developer

Thank you so much! We love hearing that the results feel studio-quality, that’s exactly the experience we want to deliver. Making professional listings possible without extra equipment or setup is a big part of our mission. We really appreciate the review!

Happy I Found This App

Been reselling for a couple years and didn’t even know something like this existed. It’s made my listings so much easier to do. The time saved is amazing and my photos look way better now. The capture guide really helps too, didn’t realize how much angle matters.

Response from developer

Thank you for sharing that Denis. Yes, once you have a good handle on how to take the captures it’s becomes quite straight forward in how to take accurate clothing measurements.

Super Consistent When Using LIDAR

I bought an iPhone 16 Pro recently and the LiDAR accuracy on this app is insane. It picks up the width, length, sleeves, all correctly almost every time. I still check with a measuring tape but it’s usually extremely close.

Response from developer

Thank your Christopher. Our goal is that measuring via tape is a thing of the past 🥳

Warehouse Approved

We process hundreds of items every week so efficiency matters. This app is incredibly fast. The LiDAR reads measurements instantly and they’re very consistent. Once I trained the team on using the capture guide, everything became extremely uniform. This literally saved us hours every day.

Perfect for cross platform sellers

I sell on Depop, Grailed, Poshmark and Mercari and this app works great on all of them. The exported pics fit perfectly and the measurements are easy for buyers to understand. I don’t get nearly as many “what’s the pit to pit” messages anymore.

Response from developer

Thank you Mao. Yep we are platform agnostic 🙃

Worth it

Hands down the most helpful reselling tool on my phone. Way better than doing everything manually. Plus, I love the model pictures that it generates, I'm already getting more views on my products.

Response from developer

Thank you, we are shipping more updates to model shots soon ;) Happy generating meanwhile 🥳

Label Scanner Is SO Helpful

This might be my fav part. I hate typing label info because the text is tiny and my eyes get tired. Size AI reads the brand, fabric, size, everything in one tap. It even picks up on old faded tags. I just paste it into my listings and move on. Such a time saver.

Saves Me So Much Time

I batch process clothes now which I could never do before. I lay out 10 items and snap them one by one. The app measures everything in under a second. Exporting is super fast too. I think my listing time is cut in half and my buyers love the consistent look. Great for anyone selling lots of inventory.
