The short answer
Both sides assessedBy the Numbers compared with Repeat Customer Insights
Both are Shopify RFM apps at very different prices.

Repeat Customer Insights compared with By the Numbers
Depth against breadth and price. By the Numbers costs $19, syncs hourly to Klaviyo, Meta, Google, and TikTok, and ships wider reporting. Repeat Customer Insights costs $59 to $249, syncs only to Shopify tags and Klaviyo, and goes far deeper on repurchase intervals, loyalty funnels, and product influence on retention, with written advice attached. Consumable brands usually get more from Repeat; stores that mainly need cheap audience syncing should take By the Numbers.
Choose By the Numbers if
Cost-conscious Shopify stores that want a real RFM segmentation model with fast audience syncing into email and paid social, plus broad reporting, without paying analytics-suite prices or waiting a day for audiences to refresh.
Choose Repeat Customer Insights if
Consumer packaged goods and consumable Shopify brands with real repeat-purchase history that want deep RFM and cohort analysis, product-level retention insight, and automatic segment syncing to Shopify tags and Klaviyo, with written interpretation rather than raw charts.

Strengths and limitations
By the Numbers
Strengths
- The lowest entry price in the category by a wide margin, starting at $19 a month.
- A genuine sixteen-cell RFM matrix rather than the simplified three-bucket version most cheap tools ship.
- Hourly audience refresh, faster than the daily sync most competitors offer.
- More than seventy-five segment filters spanning orders, products, lifetime value, and acquisition channel.
Limitations
- Almost no public information about the vendor: no named founders, no funding history, no disclosed team.
- Shopify only, with no path for stores on other platforms.
- Segments are built by assembling filters rather than described in plain language, which is slower for non-analytical users.
- No documented public API, so segments cannot be pushed into custom internal systems.
Repeat Customer Insights
Strengths
- Written advice tied to the store's own metrics, which is the interpretation layer almost every competing tool leaves to the operator.
- Deep repurchase and cohort analysis built specifically for consumables and CPG, where the second order determines the business.
- Product-level insight into which items drive retention and average order value, not just revenue.
- Automatic Shopify customer tagging and Klaviyo sync, so segments drive both store logic and email flows.
Limitations
- No sync to Meta, Google Ads, or TikTok, so paid social and search audiences must be handled elsewhere.
- Shopify only, with no support for other ecommerce platforms.
- Customer tagging requires the $99 tier, and the $59 plan is limited to two years of history.
- Considerably more expensive than the cheapest RFM apps in this category.

- EntryFrom $19
- Higher tiersPublished on the App Store listing
On paper this is the best capability-per-dollar in the category and it is not close: a sixteen-cell RFM matrix, seventy-five filters, hourly syncing, and thirty-eight reports for a starting price under a fifth of what Tresl charges and a third of Repeat Customer Insights. The question is not whether it is cheap, it is whether the vendor is durable, since there is no public corporate information behind an app around two thousand stores now depend on. For a store weighing $19 against not segmenting at all, that risk is easy to accept. For one about to make it the backbone of every audience in Meta and Klaviyo, keep the segment definitions documented somewhere you control.
Repeat Customer Insights
Flat monthly subscription in three tiers sold through the Shopify App Store, rising by depth of analysis, history included, and number of sales channels.
- Entrepreneur$59
- Growth$99
- Peak$249
At $59 to $249 this is priced above the cheap RFM apps and below the analytics suites, and what the premium buys is interpretation. By the Numbers gives more raw segmentation surface for $19 and syncs to more ad platforms; Repeat gives deeper repurchase and cohort analysis with written advice attached and a decade of continuous operation behind it. For a consumables brand where the second order decides the business, the analysis depth is worth the difference. For a store that mainly needs audiences pushed into Meta and Google, it is not, because those syncs do not exist here.
Editorial verdict on each
By the Numbers
By the Numbers is the best capability-per-dollar in customer segmentation, and the gap is large enough that price alone settles many decisions. A real sixteen-cell RFM matrix, seventy-five filters, hourly syncing into Klaviyo and the ad platforms, and a broad reporting layer starting at $19 is not a stripped-down version of what competitors charge $150 for, it is most of the same job done more cheaply and, on refresh speed, done better. Two caveats. The vendor publishes essentially nothing about itself, so keep your important segment definitions written down somewhere you control, and confirm on the App Store listing which tier actually includes the sync before assuming the entry price covers it. For a Shopify store that has been putting off segmentation on cost grounds, there is no longer an excuse at this price.
Read the full By the Numbers profileRepeat Customer Insights
Repeat Customer Insights is the most analytically serious tool in this category and the one most likely to change what a consumables brand actually does. Repurchase intervals, loyalty funnels, and product-level influence on retention are the measurements that decide whether a CPG business compounds, and the written advice layer converts them into decisions in a way no competing app attempts. The limitations are specific and easy to check against your own needs: activation stops at Shopify tags and Klaviyo, with no Meta, Google, or TikTok syncing, and the useful tier is $99 rather than the $59 headline. The vendor is one developer, which is both the reason support answers within a day and the risk you accept. If the second order is what your business runs on, this is the tool to buy; if you mainly need audiences in ad platforms, buy elsewhere.
