Best Shopify Upsell and Cross-sell Apps

The 30 strongest of the 1,112 upsell and cross-sell apps in our index of the Shopify App Store category chart, scored on four things we measure ourselves: how many stores use it, how well those stores rate it, whether it is gaining or losing ground, and what it costs. No editor picks the order, and nobody can pay to move up it.

The short answer

Five ways to be the right upsell and cross-sell app. Each award is the highest scorer that fits it, and no app can win twice.

Best overall

The highest total score in the category: 2,399 reviews at 5.0, and 99.3 out of 100 on adoption against every other upsell and cross-sell app.

Best paid app

No free tier, so the price component holds it down the ranked list — but 367 merchants rate it 5.0, and it starts at $4.99/month.

Fastest growing

Gained 882 reviews in the last 10 days and climbed 1 places in the category chart.

Most established

3,498 reviews — more than anything else Shopify files under upsell and cross-sell — and still rated 5.0.

The full ranking

Sorted by BestAppify Score. The four bars under each app are its percentile within this category on each component — a 90 on adoption means only a tenth of upsell and cross-sell apps have more reviews.

How the score is calculated

The BestAppify Score is four measurements, each turned into a percentile against the other upsell and cross-sell apps and then weighted. It is computed from our own crawl of the App Store — no human ranks these, and no app can pay to move.

Adoption35%
Review count on a log scale. It is the only public proxy for how many stores actually run the app, and the log stops a single 43,000-review incumbent from flattening everything beneath it.
Satisfaction30%
The star rating, shrunk toward the category average in proportion to how few reviews back it. Half of all rated Shopify apps show exactly 5.0 off a median of four reviews, so the raw number separates almost nothing.
Momentum20%
Reviews gained and category-rank movement over the last 52 days, from our own daily snapshots of the App Store charts. An app losing ground scores badly here even if its lifetime totals look strong.
Price15%
A plan a live store can stay on for $0 takes the top of this component; paid apps are ranked cheapest-first across a narrower band, so price nudges the order without overruling thousands of merchants.

What it cannot see: whether the app is any good at the job. Nothing here reads the feature list or installs the app, so treat the score as a shortlist, not a verdict — it tells you which three or four of these 30 are worth an hour of your evening, and no more than that. Apps whose pricing the crawler could not read score below the paid range on price rather than in the middle of it, deliberately: a price you cannot check before installing is a cost too. Momentum is measured over the last 10 days — the run of days on which our coverage of this category has been complete enough for one day's rank to mean the same thing as another's. It is deliberately shorter for categories we finished crawling recently: a rank of 4th out of the 28 apps we had in July is not comparable to 6th out of 436 today, and treating it as though it were would have scored every established app in some categories as falling.
