Loox vs Tiergain in 2026: photo reviews or bundle architecture?
Loox shows customers that others love the product. Tiergain shows them how to buy more of it at a better price. Trust first, then cart size.
Quick Verdict
Loox builds trust with photo reviews. Tiergain builds bigger carts with bundle architecture. Reviews convert browsers. Bundles convert single-item buyers into multi-item buyers.
What is Loox?
Loox is a Shopify photo review app that collects and displays customer photos alongside text reviews. It offers automated review request emails with photo incentives, review carousels, and UGC galleries. Pricing starts at $9.99/month with a 14-day free trial. It has a 4.9 rating across 18,000+ reviews and is one of the most popular review apps on Shopify.
Where Loox Falls Short
Trust Signal, Not AOV Architecture
Loox builds trust through visual social proof. It does not build bundle experiences, tiered pricing, or progressive rewards that lift cart size. A product with beautiful photo reviews still sells one item at a time.
No Bundle Builder or Cart Rewards
Loox displays photos and reviews. It does not create mix-and-match bundles, tiered offers, or combined reward systems. The shopping experience stays the same - only the trust level changes.
Reviews Lift Conversion, Not Cart Size
Photo reviews lift the percentage of visitors who buy. Bundles lift how much each buyer spends. A 20% conversion lift on $42 orders generates less than a 22% AOV lift on the same traffic.
Different Problem, Complementary Solution
Loox answers 'should I buy this?' Tiergain answers 'how much should I buy?' Both questions need answering. They require different tools.

Why Merchants Switch to Tiergain
22-34% AOV lift from bundles complements the conversion lift from reviews
Loox lifts conversion 15-25% through photo trust. Tiergain lifts AOV 22-34% through bundle architecture. Together: more buyers spending more per order. The compound effect is multiplicative.
Reviews get one item in the cart. Bundles get three.
A stunning photo review convinces a visitor to buy the serum. A routine bundle convinces them to buy the serum + cleanser + moisturizer. Reviews solve trust. Bundles solve cart size.
Both apps cost under $60/month combined
Loox at $9.99/month + Tiergain Pro at $50/month = $59.99 total. The combination lifts both conversion rate and AOV. The ROI from running both exceeds running either alone by 3x.
