Before Desertcart Bet on a New App, We Handed It to Real Shoppers.

Desertcart is a Dubai-based marketplace that ships hard-to-find products to the UAE and beyond. With a redesigned app, a new visual direction, and a paid “Pro” tier all on the line, they needed to know one thing before launch: would real shoppers actually get it? We ran the research to answer that — and handed back a prioritised roadmap, not just opinions.

The Client

A global marketplace, betting on a bolder experience

Desertcart lets shoppers in the UAE and beyond buy products that are otherwise hard to find in the region — a huge, global catalogue delivered locally. To grow, the team had reimagined the mobile experience: a cleaner, more expressive design, new AI-powered features, and a paid “Pro” membership. It was a big bet — and betting on a redesign without testing it is how good ideas quietly lose money.

The Brief

Three questions, one relaunch riding on the answers

Desertcart didn't need opinions — they needed evidence. Before committing engineering to the relaunch, three things had to be de-risked:

Does the new app make sense?

Could real shoppers navigate the redesigned prototype, find what they wanted, and grasp the new features — without a guide?

Which visual direction wins?

Two brand directions were on the table — expressive vs. minimalistic. Which one actually helped people shop?

Will anyone pay for Pro?

The new paid membership had to convert. What would make shoppers say yes — and what was quietly killing the upsell?

How We Tested It

Eight shoppers, thinking out loud

We ran eight moderated, remote think-aloud sessions — four with existing Desertcart shoppers and four with first-time visitors — watching real people use the prototype live, narrating every hesitation, misread, and “wait, where's the search?” moment. We recruited across four distinct shopping behaviours too, so the findings held across the customer base, not just one type of buyer.

Peter

Power buyer, mobile-first — shops often, moves fast, low patience for friction.

Sailee

Snack hunter, desktop-first — browses for niche finds on a bigger screen.

Frank

Trust-focused health shopper — needs reassurance on authenticity and pricing.

Anvaya

Price-sensitive essentials buyer — weighs every fee before committing.

What We Found

What clicked — and what quietly cost conversions

The redesign got a lot right. But the moments that break trust in a marketplace — a hidden search, a price that changes at checkout — were exactly the moments that tripped shoppers up.

Validated — what shoppers loved

The new look landed

Cleaner UI, clear hierarchy, and instant price + savings on every product tile.

AI Photo Search was a hit

Testers kept calling it “powerful and convenient” — a genuine differentiator worth leaning into.

Pro perks read clearly

Badges, perk lists, and free-shipping labels made the membership's value visible at a glance.

Local theming resonated

Seasonal touches like the Eid banner and regional models felt made-for-me.

Friction — what tripped them up

The search bar hid

A shopper's first instinct is to search — and they couldn't find the search.

Prices didn't match

Listing price ≠ cart price. Nothing erodes trust in a marketplace faster.

Onboarding felt like ads

Splash screens got in the way — and desktop users were shown a mobile-only flow.

New features went unexplained

A cryptic “AI Find” label meant a great feature quietly went undiscovered.

Existing vs. New Users

The same app, two different jobs to do

The sharpest finding wasn't about a button — it was about who's tapping it. Existing shoppers had already banked their trust, so they optimised for speed. For first-timers, trust was the whole task. Same prototype, two very different jobs to do.

Existing shoppers · UAE

Trust is banked — make me fast

  • Optimise for speed and consistency: visible search, snappy filters.
  • Loved the expressive look — colour pop and the savings tracker.
  • Pro-ready: the most likely to convert to paid membership.
  • Want a skip-able, efficiency-first onboarding.
New visitors · India

Trust isn't banked — prove it first

  • Legitimacy first: brand story, returns policy, payment options.
  • Preferred a cleaner, minimalist look — it reads as safer.
  • Need localisation: local currency, clear duties, familiar payment (UPI).
  • Want a short, educational intro before any premium ask.
Common groundBoth audiences demanded the same non-negotiables: a sticky, always-visible search · prices in local currency · visible trust badges.

Our synthesis for the team: one core funnel, three tuning dials — show instant value to heavy buyers, surface legitimacy signals for first-timers, and localise fees and payment methods per market. (One caveat we flagged honestly: existing users skewed UAE and new users India, so tenure and market overlap — worth isolating in a follow-up round.)

The Verdict

Expressive or minimalistic? Wrong question.

“Visual style doesn't change what shoppers actually need — trust, speed, and clarity. New visitors leaned minimalistic; power users just wanted efficiency. The winning direction wasn't one or the other. It was expressive warmth on a minimalistic structure.

The Roadmap

12 fixes, ranked by what to do first

We didn't hand over a wish list. We handed over a prioritised roadmap — what to fix now, next, and later — each tied to a real user and a real moment of friction.

01
Now · Critical friction removers

Fix the trust-breakers first

  • Make search omnipresent and sticky, on mobile and desktop.
  • Skip or shorten the onboarding splash screens.
  • Lock “the price you see is the price you pay” across every screen.
  • Rewrite the fee and duty banner in plain English.
02
Next · Trust & transparency

Earn confidence, then upsell

  • Trigger Pro promos for episodic shoppers at the right moment.
  • Add real-time stock and delivery alerts.
  • Rename and explain new features — goodbye, cryptic “AI Find.”
  • Batch filters into a single refresh for speed.
03
Later · Catalogue & value

Deepen the reason to come back

  • Rebalance the catalogue and expand everyday essentials.
  • Introduce transparent, capped shipping tiers.
  • Add a price-match / “found it cheaper?” flow.
  • Sharpen how Pro's value is communicated.
The Pro Tier

Turning a nice-to-have into a yes

The paid membership had real appeal — but doubt was quietly winning. Shoppers were pulled in by free shipping, a visible savings tracker, priority-delivery badges, and risk-free cancellation. They were held back by three things: “it's not worth it if I only shop now and then,” fuzzy benefit math, and a real fear of hidden auto-renewals. The play we recommended: surface the savings, prove the flexibility up front, and time the upsell to a moment that already stings — like a big shipping fee at checkout.

The Impact

A relaunch backed by evidence, not hope

A build-ready roadmap

Prioritised fixes, sequenced Now / Next / Later — not a wish list.

A clear brand verdict

Expressive warmth on a minimalistic structure — decision made, not debated.

Audiences decoded

Existing vs. new shoppers — each with its own onboarding and Pro strategy, not one-size-fits-all.

Desertcart went into its relaunch knowing what worked, what would quietly cost conversions, and exactly what to fix first — before a single engineering sprint was spent on the wrong thing. That's the whole point of testing before you ship: the cheapest bug to fix is the one you catch in a prototype.

Why This Matters For You

A redesign you haven't tested is just an expensive opinion

It's easy to fall in love with a new design in Figma. It's expensive to find out — after launch — that shoppers can't find the search bar or don't trust the price. Four well-run sessions cost a fraction of a botched relaunch, and they turn “we think” into “we watched them.” If you're about to bet on a redesign, a rebrand, or a new paid tier, that's the cheapest insurance you can buy.
