Neither Retention.com nor Wetracked is Littledata, so here's where Littledata wins:
Retention.com focuses narrowly on recovering lost shoppers via identity resolution and Klaviyo flows. It lacks direct server-side Shopify data collection, limiting event completeness, and doesn't offer no-code setup or a free trial.
Wetracked pulls data directly from Shopify's servers and offers no-code setup — matching Littledata on those points. However, it lacks a 30-day free trial, native Shopify Markets support, and automatic checkout step tracking.
Littledata wins on:
For a Shopify Plus brand prioritizing accurate, full-funnel data across markets, Littledata offers the most comprehensive out-of-the-box solution.
Retention.com vs Wetracked's customer reviews
| Retention.com | Wetracked | Littledata | |
|---|---|---|---|
| Example product review | they got me in as they said it was better and cheaper then Triple whale, but really all it is, is some code on the back end you can not track or even see the results you still need to use the meta and good dash boards. | "We were having difficulties with accurate and consistent revenue attribution...With Littledata implemented, we now get consistent and accurate revenue attribution." | |
| Example support review | "Unfortunately, the team... very high employee turnover; it can be really frustrating to have to re-explain things to new reps." | Tracking looks improved the last 2-3 days. Support has never replied to me :-( even after days of waiting and 3 emails & reminders. | "Customer support is absolutely amazing... you can never go wrong when an app does what it says and tacks on great service!" |
