For Shopify stores selling products priced by size, area or quantity
Your price depends on the size.
Most apps can add $10 for a finish. They can’t take 14 feet by 9, work out the area, drop the rate after 25 units, and stop at a $95 minimum.
That’s not a choice from a list. That’s math. Appify was built to do the math. Pick the product closest to yours and watch it price.

Why the search took this long
Options apps are easy to find. Ones that do the math aren’t.
The search gets stuck on one of these four.
Most apps add $5 for a finish. Yours needs 14.375 inches against a rate card, 22% off at 25 units, and a $95 floor. That’s a formula, a table and a rule at once. Most apps can’t say it.
Nobody spends $600 on something they’re imagining. Show it at true scale. Let them drop their artwork on it and approve it before they pay.
Options apps stop at the order confirmation. Somebody still has to make the thing. Every order lands with the measurements, an approved proof and a print-ready file with bleed and a cut line. Nobody retypes specs into Illustrator at 8am.
Most apps get close, so you settle and build the whole catalogue that way. Fixing it later means rebuilding every product, option and rate. Here, the hard product works on day one.
How the app store actually splits
One kind of app adds choices to a product. The other puts a price on a choice.
Neither can price a measurement, show it at scale, or hand production a file.
Appify was built for all three.
Sell complex products other apps canât price, preview, or produce.
Every app lists the same features. Swatches, text fields, uploads, conditional logic.
That list tells you nothing. What separates them is the pricing underneath.
Ask these before you install the next one, Appify included.
Eight yeses is rare. Take the list to whichever app you look at next and get an answer to each one before you commit to it. Or get started with Appify and stop searching.
What your sales reports don’t show you
Someone was ready to buy, hit something the page couldn’t do, and left without a word.
Nine ways it happens. Under each one, the thing that stops it.
Install. Build a test product. Enter a real measurement. Find out it can’t. Uninstall. Then do it again with the next one.
→ Eight questions that rule an app out in two minutes, without installing itYour price list has rates, breaks and minimums. The app couldn’t, so sizes went into buckets with one price each. Every bucket overcharges someone or gives margin away.
→ Your actual price list on the page: rates, breaks, minimums, and sizes to the eighth of an inchThe app couldn’t handle the way that one is priced, so it came off the page. Somewhere along the way you decided it isn’t something you sell.
→ Price adjustments, fixed fees, quantity discounts, limit and value rules, and a price built from any option or variableThey wanted a number. You offered a form and a promise to email them back. The shop down the road gave them a number in four seconds.
→ Any price calculated instantly, however complex the productA quote builder on the home page. A landing page that ends in a price, not a contact form. If a calculator only runs on product pages, none of those exist.
→ Put a working calculator on any page, add to cart includedMost of your traffic is on a phone. A calculator that loads late, shoves the page down, or fights your theme loses sales without ever telling you.
→ Rendered on the server with the page: no wait, no jump, and your theme’s own add to cartThey sized a 14 by 9 wall, reached checkout and stopped. The recovery email works, but Shopify’s link drops the options. The cart comes back without the sizes and at the wrong price.
→ Restore the whole cart with every option and the right price on itWhat size did you want? Can you resend the file? Is this the right crop? All questions the product page could have asked.
→ Measurements, an approved proof and a print-ready file on the orderShe ordered 40 feet in March. In September she wants the same again. The page can’t remember, so she’d have to rebuild it all. She doesn’t.
→ Reorder puts the whole order back in the cart, options and files attachedNone of these nine show up in analytics, so none of them ever make it onto a list to fix. They just keep happening. Install Appify, build your hardest product first, and you’ll know inside a week which of them were costing you.
Once youâve found the one that works
Finding the app was the hard part. Building the product takes an afternoon, not a project.
Open the closest template and change the rates. Or tell the AI what you sell in plain English, or hand it a screenshot of a calculator, and it builds the options for you.
Type how you quote a job and the AI writes the formula. Rates, tables, minimums, breaks. Ask what any rule does and it answers in plain English.
Native add to cart. No Liquid, no new variants, nothing to break. Work in draft, publish when youâre ready, roll back any version.
Nothing is hard-coded into the theme. Rules read from the product and variant, so one setup runs the whole catalogue, and your next build starts from your own template.
Free on Shopify Partner dev stores, so you can build the whole thing before a client pays anything.
The parts every setup uses
The pieces every build uses, whether the product is a sticker or a staircase.
Each one is a working demo on our store. Go operate it.
The ones that surface later
Nobody weighs these while choosing an app.
All three turn up later, when the catalogue is too big to rebuild.
A shopper in another market sees your home currency and has to work out what it really costs them. Most of them don’t bother.
→ Reads your Shopify Markets rates, so option prices, fees and the total all convert. Nothing to set up in the appYour store is translated. The calculator isn’t, so the options, the prices and the buttons are still in English. Customers can’t order what they can’t read.
→ Up to 10 languages per calculator, options and summary included, with an AI pass that does the bulk in one goYou change a price, it comes out wrong, and there is no way back. The setup you had is gone.
→ Every publish is saved as a version, so a bad change is one click from undoneCustom work fails at the imagination step. Customers can’t picture a 24 by 36 sign or a pattern on a real wall. So they hesitate, ask, or leave.
The Product Designer puts a real artboard on the page. Customers add text, clipart and their own images, and the canvas resizes with the product, so what they see stays true to what they’re ordering.
Two tools, chosen per product. A personalizer overlays their choices on your product photo. A designer hands them an artboard. Some products want one, some the other, plenty both.
Not a line item and a note to chase.
Every order carries the numbers, the approval and the files, in formats production already uses.
Reorder and cart recovery
The measurements, the material and the artwork were the order.
Ask a customer to rebuild all that and your easiest sale turns into work.
Every product type here runs as a real configurator on our demo store. Size a wall, spec a blind, watch the price move. No install, no signup.
Under the hood
You wonât need all of this. Itâs here because somewhere in it is the one rule that makes your hardest product finally work on a product page.
14-day free trial with every feature turned on. From $39/month after.
Support comes from the people who build the app. Ask a hard pricing question and you won’t be explaining your trade to a stranger first.
Most merchants here don’t. Describe your pricing in plain language and the AI builds it, or start from a template. Support will build the awkward one with you.
That’s the easiest time. Get the pricing right before orders depend on it. Partner dev stores are free, so build and test everything before anyone pays a cent.
For options, most work fine. Can yours price from a measurement, block a size you can’t build, and hand production an approved file? If that still happens by email, that’s the part this replaces.
Those are just the ones with demos ready. The engine runs on measurements, options and rules, not categories. If you can explain how you quote it, it can be built.
No. Everything renders with the page and adds to cart natively. No separate cart flow.
No. The designer is optional per product. Plenty of stores run pricing and previews with uploads off.
Go and use it. The demo store runs all of these as real configurators. Operate one as a customer would before installing anything.
Every feature is on every plan. Nothing is held back for a higher tier.
From $39 / month
The subscription scales with calculator usage. Monthly AI credits included, with an overage charge only past them.
Or try it live first if you'd rather see it working before you install.
Not the simple one. The one you quote by hand.
The one with the rule nobody can write down.
The one that generated four emails last week.
If it can't handle that one, you'll know inside a week and you won't have paid anything.
14-day free trial. Free on Shopify Partner dev stores.
Anything priced by size, material, quantity or configuration rather than a fixed variant. Stickers, wallpaper, blinds, flooring, signs, print, upholstery, glass, framing and fabrication all work the same way.
No, it’s the best time. Build the pricing before you have live orders and nothing has to migrate later. Partner development stores are free, so you can test the whole setup before opening.
No. Start from a template and change the rates, or describe your pricing and the AI builds it. Nothing is added to your theme code.
Yes. Area, length, perimeter, volume and coverage are calculated from what the customer enters, with your rates, minimums and discounts applied on top.
No. Options and pricing live outside the variant system, so no combination of size and material ever becomes another SKU.
No. Describe your pricing in plain language and the AI builds it, or start from a template and change the rates.
Yes. Rules show, hide and require fields based on earlier answers, so customers never see an option that doesn’t apply.

Orders can carry the measurements, all selections, an approved proof PNG, a print-ready PNG with bleed, a cut-line SVG and the canvas JSON for later re-editing.
Yes. A past order goes back in the cart with every option and file intact, from the order or the customer’s account portal.
Yes. Recovery emails restore the full configuration, not an empty configurator.
