Store rehearsal for Shopify
Your store, in the hands of 90 different customers.
Prova sends 90 synthetic shoppers from six age groups into your store, each with their own phone, connection speed and text size. Can they find a product, add it to the cart and reach checkout? You get a report with every tap as evidence.
One-time payment · free re-run after your fixes · no order is ever placed

Meet your shoppers
Fifteen people from every age group. Not one average user.
Your team tests the store on fast phones with perfect eyesight. Your customers do not. Each Prova shopper gets their own device, connection, text size, habits and patience, based on typical behaviour for their age.

Shares are the model's weights for each age group. The same seed gives the same 90 people every time, so a re-run compares like with like.
Watch them shop
Every shopper, every step, live.
While the rehearsal runs, you see each shopper move from the home page to search, product, cart and checkout. Anyone who gives up is marked, with the reason.
From a real rehearsal of a live Shopify store, 16 October 2026.

A real finding
5 shoppers tapped a product and landed on the FAQ.
On a live store, a card in the search results had an invisible clickable layer that covered the product above it. Nobody on the team had noticed: on their own phones, it looked fine. Prova caught it because 25 different people searched.
One line of CSS later, the same 90 shoppers came back.

What Prova catches
The problems you cannot see on your own phone.
- Taps that go to the wrong pageAn invisible layer covers a product, so a tap opens something else.
- Tap targets that are too smallButtons and links under 44 px that older shoppers miss.
- Pages that load too slowlyPages that take longer than a shopper is willing to wait, on 4G or 3G.
- Search that finds nothingNo search icon on mobile, or no results for common words.
- Menus that hide productsCollections that cannot be reached from the mobile menu.
- Add to cart that failsMissing button, no feedback, or an error in the wrong language.
- Checkout that is hard to reachNo visible checkout button in the cart drawer or cart page.
- Pages wider than the screenSideways scrolling on phones, usually from an image or table.
Marked issues are always reported as high priority, even if only one shopper hit them.

Questions
Is it safe for my store?
Yes. Shoppers browse, add one product to the cart and open checkout, and that is where they stop: no order is placed and no payment form is filled in. Checkout is only read.
Will it show up in my analytics?
Yes, honestly: one rehearsal adds about 90 sessions and add-to-carts to your Shopify analytics on the day it runs. No customer email is entered, so no abandoned-checkout emails are sent.
Why do I add a tag to my theme?
It proves the store is yours. Only someone who can edit your theme can add it, so nobody can send Prova to a store they do not own. You can remove it after your re-run.
Are these real people?
No. They are synthetic shoppers in a real browser. Their devices, connection speeds, patience and habits are modelled on typical behaviour by age, not measured from your visitors. Prova finds friction; it does not predict your conversion rate.
Which stores work?
Shopify stores, live or password-protected (enter your storefront password when you order). Other platforms are coming.
How long does it take?
A rehearsal takes about 10 minutes once it starts. Runs are queued one at a time, and we send the report by email when it is ready.
What if something goes wrong?
If a rehearsal cannot complete for a reason on our side, you get a full refund.
