Unexpected shipping cost is the classic cart killer. Kernvel Shipping Calculator shows shoppers their real rates while they're still in the cart, and a free-shipping progress bar gives them a reason to add one more item.
Shoppers who reach checkout and meet a surprise rate don't negotiate — they leave. Showing the rate one step earlier removes the surprise entirely.
"You're $12 away from free shipping" is the most honest upsell in commerce — it rewards the shopper and lifts your average order value at the same time.
When a shopper picks a country and gets no rates back, that's a lost sale and usually a missing shipping zone. The app counts every one and shows you exactly which markets are failing.
Best for stores fighting cart abandonment and low order values. Every feature below ships in the free app — there are no paid tiers.
Country, province, and ZIP aware — quotes come straight from your Shopify shipping settings via Shopify's own endpoints. The app never invents or alters a rate.
Up to eight tiered goals (free shipping, free gift, anything you configure) with live progress as the cart changes, in the cart page and the drawer.
Colors, radius, font, placement, and every label are configurable — and rate names can be renamed, badged, or hidden for display without touching the underlying rate.
Daily counts of bar impressions, rate lookups, and free-shipping goals reached — aggregate counters only, never shopper profiles.
See where shoppers actually check shipping to, country by country — real demand signal for your next shipping zone or market.
The report you can't get from Shopify: every lookup that returned zero rates, grouped by country, so you can fix the gap before the next shopper hits it.
Enable the app embed, drop the block where you want it, and the bar and calculator pick up your theme automatically.
Configure the free-shipping threshold and tiers, wording, and looks in the admin — changes publish straight to the storefront.
Watch impressions, lookups, top destinations, and no-rate markets — then fix zones and thresholds with real data.
No plans, no feature gates, no surprise charges. These tools are how we earn trust with merchants — and every one includes a free concierge setup call with our team.
No subscription, no usage caps, no premium tier hiding the good parts. The app you install is the whole app.
Rule-based and deterministic — no AI black boxes. You can always see exactly why the app did what it did.
No shopper profiling, aggregate-only counters, minimal Shopify permissions, and data that cleans up after itself.
Never. It displays the rates your Shopify settings already produce, fetched live through Shopify's own cart endpoints. Display-only renames and badges never alter what's charged.
No. The widget's configuration is baked into the page via a metafield — no backend call on page load — and analytics beacons are fire-and-forget.
No profiles, ever. Analytics are aggregate daily counters; the only destination data recorded is a country code.
Both widgets, all customization, and all analytics. No plans, no limits.
Every Kernvel Free Tool comes with a free concierge setup — a 15-minute call where our team configures the app for your store. That's the whole pitch: useful tools, set up properly, no invoice.
