TL;DR
ProfitWell Metrics (now part of Paddle) is a free, accurate subscription-metrics dashboard, monetised through add-ons like Retain (dunning) and price optimisation. RetentionLens offers a 14-day free trial, but its differentiator is predictive churn — survival analysis and customer health scoring that tell you who is likely to churn next, rather than only reporting what already happened.
ProfitWell Metrics is popular for good reason: it is free and the numbers are accurate. Paddle monetises around it with Retain (failed-payment recovery) and pricing tools. If you want a free, reliable read on MRR and churn, it delivers.
“Free†metrics still cost you something when they stop at description. RetentionLens offers a 14-day free trial, but adds predictive churn modelling and health scoring on top — the forward-looking layer that helps you intervene before a customer leaves.

Frequently asked questions
Is RetentionLens a ProfitWell alternative?
Yes. ProfitWell Metrics is free and accurate for descriptive reporting. RetentionLens offers a 14-day free trial but adds predictive churn (survival analysis) and customer health scoring, so it is the better fit if you want forward-looking retention signals rather than only historical metrics.
If ProfitWell is free, why pay for RetentionLens?
You don’t have to pay to start — RetentionLens has a 14-day free trial (credit card required — not charged for 14 days). You upgrade when you want the predictive layer: knowing which customers are likely to churn next and how healthy each account is. That is not part of ProfitWell’s free metrics.
Does RetentionLens recover failed payments like ProfitWell Retain?
Yes — RetentionLens includes dunning (failed-payment recovery) with smart retry logic and in-app cancellation flows. Paddle Retain specialises in recovery; RetentionLens adds predictive churn analytics (survival analysis, health scoring) so you can intervene before the cancel moment.
Is RetentionLens tied to a billing provider?
No. RetentionLens is an independent analytics tool that connects to your Stripe account. ProfitWell Metrics is part of Paddle, so its roadmap and monetisation are tied to that ecosystem.
