Every subscription app eventually asks the same question: how much should we give away before we ask someone to pay? Get it right, and the app builds a steady base of subscribers who stick around. Get it wrong, and user acquisition (UA) teams end up chasing installs that never turn into revenue.
However, that question is bigger than product design itself. The subscription model an app chooses: free trial, freemium, or paid subscription, also shapes the kind of user it attracts. It extends to the types of promises its ads have to make, and the time it takes to know whether a UA campaign is actually working. Two apps can spend the same budget on the same channels and walk away with completely different answers, simply because their access models create different paths to payment.
This guide breaks down what separates the three models, how each one changes mobile user acquisition, and which subscription metrics UA and growth teams need to track to know whether their campaigns are creating durable revenue, beyond installs.
What Is the Difference Between a Free Trial, Freemium, and a Paid Subscription?
The simplest way to understand the three models is to separate an offer from an access model.
For example, a free trial is an offer. It gives a user a limited window to experience premium features before a paid subscription begins, unless they cancel. A language-learning app might give someone seven days of full access before charging for an annual plan.
Freemium is an access model. Users can stay on a free tier indefinitely, while premium features, more content, or higher usage limits are reserved for subscribers. For example, a photo-editing app might offer basic tools for free, then require a subscription for unlimited exports and advanced effects.
A paid subscription model is also an access model. The product’s core value is available through a recurring plan, usually occurring at a monthly, annual, or another billing interval. It can still include a trial, a discounted first period, or a limited preview. Those offers do not make the product freemium.
| Subscription Model | User Experience | Revenue Path | Acquisition Goal |
| Free trial | Temporary premium access | Trial converts to paid subscription | Does the campaign acquire users likely to convert and stay? |
| Freemium | Permanent free tier with optional premium upgrade | Free user upgrades directly or starts a premium trial | Does the campaign acquire engaged free users who later become subscribers? |
| Paid subscription | Continued access through recurring payment | Direct subscription, often after a trial or offer | Does the campaign acquire subscribers who generate recurring revenue? |
It’s important to note that a fully free app is different from a freemium model. A fully free app provides ongoing access without a required subscription and most likely monetizes through in-app advertising (IAA), in-app purchases (IAP), commerce, partnerships, or a mixed (hybrid) monetization model of those types. If there is no upgrade path to a subscription, then lifecycle subscription metrics will not be part of its main performance view.
It is also worth avoiding the phrase “free subscription model.” This can refer to a permanent free plan or a time-limited free trial and they represent two very different user journeys. For our purposes, in this article, free tier ou free plan means ongoing access; free trial means temporary premium access.
Subscription Models Relate to UA Objectives
With a free trial, ads need to set up the value users will experience quickly. A campaign may successfully generate trial starts because the offer has low friction, but that does not mean it has found the right audience. If users start a trial and cancel before the first charge, the campaign has created activity without creating much revenue.
Com freemium, the journey is usually longer. A user might install because the free tier solves an immediate problem, then upgrade only after they reach a limit or see a reason to pay. That makes free-user volume a weak proxy for value. A channel that produces fewer installs may be more valuable if its users are more likely to engage, reach the paywall, and subscribe later.
With a paid subscription model, the commercial moment comes earlier, but subscriber quality still takes time to prove. A campaign driving affordable annual subscriptions may look strong on day one. A second campaign with a higher cost per install could be better if its subscribers renew more consistently. First payments matter, but they are not the whole return-on-ad-spend story.
This is why subscription apps should align the promise in their creative with the experience after install. If an ad suggests instant access to one type of value but the paywall, product, or trial experience suggests another, cancellations can rise even when trial volume looks healthy.
How to Choose a Subscription Model for Your App
There is no universally best mobile app subscription model. The right one depends on the nature of the product, how quickly people experience its value, and what the business can sustainably give away.
Start with five practical questions:
- Is the value recurring?
Subscriptions are strongest when users have a reason to come back. That translates to promoting new content, ongoing coaching, personalized insights, regular utility, or a service they rely on continuously. - Do users need time to understand the product?
A free trial can help when the value only becomes clear after several sessions. But a trial should be long enough for users to experience that value, not simply long enough to increase trial starts. For example, a lot of health apps require time for a user to get to know the product and see potential benefits. - Can a free tier be useful without replacing the paid product?
A freemium tier can support reach and product discovery. It also has a cost: free users consume support, infrastructure, and product attention. The upgrade path must be clear. - What is the job and main purpose of the paywall?
It should sit after a meaningful value moment, not merely block the user before they understand why premium access matters. - Can the team measure downstream value by acquisition source?
Without a clear funnel, it is easy to optimize toward the cheapest install, the highest trial volume, or the most first-time subscriptions, even when another campaign is generating better long-term revenue.
All of these questions should be considered when choosing the best sort of subscription model for your app. A subscription model is only as useful as the measurement framework behind it.
Why Trial Starts and New Subscriptions Are Not Enough
Trial starts and new subscriptions are important. They indicate that a campaign can move users into the paid journey. But they do not reveal whether those users will remain valuable after their first decision.
Consider two acquisition campaigns for the same app. Campaign A generates 1,000 trials at a lower cost, while Campaign B generates 700 trials at a higher cost. If Campaign A’s users cancel before renewal and Campaign B’s users continue paying, Campaign B may create more revenue despite its weaker top-of-funnel numbers.
The same applies to first-time paid subscriptions. One channel may generate many monthly subscribers during a promotion, while another brings in fewer annual subscribers who renew at a stronger rate. Looking only at new subscribers can hide that difference.
Subscription measurement needs to answer three related questions:
- Conversion quality
Which campaigns bring in users who start a trial or subscribe? - Retention quality
Which campaigns bring in users who renew rather than cancel? - Revenue quality
Which campaigns create the most subscription revenue over time?
These questions matter whether the app uses a trial, freemium, or direct paid model. The journey may begin in different places, but the growth goal is the same: acquire users whose subscription value exceeds the cost of acquiring them.
Which Subscription Metrics to Measure?
Once a user enters a subscription lifecycle, teams need a view of both movement and value. Tenjin’s iOS Subscription Revenue Report includes six core metrics that make that lifecycle easier to evaluate alongside acquisition and spend data.
Novos ensaios clínicos
New Trials shows the number of users beginning a subscription trial. It helps identify campaigns that generate interest in the premium experience, rather than installs alone.
For a trial-led app, this is an early signal, not a final result. Use it to see where initial intent comes from, then compare it with new subscriptions, cancellations, and renewals to understand whether that intent turns into lasting value.
Novas subscrições
New Subscriptions shows first-time paid subscriptions. These may come from users who convert after a trial or users who subscribe directly.
This metric is useful for understanding first conversion, especially when comparing paywall offers or acquisition sources. It should still be read alongside renewals — a campaign is not necessarily valuable just because it drives a large number of first payments.
New Subscription Revenue
New Subscription Revenue measures revenue from first paid subscriptions. It gives important context that subscriber counts cannot provide on their own.
For example, a campaign driving annual subscriptions can generate more immediate revenue than one that drives monthly subscriptions, even if both generate the same number of new subscribers. Analyzing by Product ID can help teams see how different plans, tiers, or offers contribute to that result.
Renovações
Renovações show the number of subscriptions that continue into another billing period. It is one of the clearest indicators that users are receiving enough ongoing value to keep paying.
Renewals are especially important when comparing campaign quality. A source that generates fewer initial subscriptions may still be the stronger investment if the subscribers it acquires continue at a higher rate.
Renewal Revenue
Renewal Revenue measures revenue from subscribers who continue paying. It turns retention into a financial signal, making it easier to see whether acquisition activity is creating recurring value rather than only a first transaction.
This is where the MMP perspective matters. Renewal data becomes more actionable when it is connected to the campaign that acquired the subscriber. It helps teams evaluate whether a higher acquisition cost is justified by stronger downstream revenue.
Cancelamentos
Cancellations shows users who choose not to continue their subscription. A cancellation does not always mean access ends immediately — a user can turn off auto-renewal and retain access until the current paid period ends.
Even so, it is an important early warning signal. Higher cancellation activity from one campaign can indicate a mismatch between the audience, the creative promise, the offer, or the product experience. It is a cue to investigate, not proof of a single cause.
How to Calculate Total Subscription Revenue
The six metrics above describe the subscription lifecycle. To assess the revenue outcome of that lifecycle, combine the two revenue metrics:
Total Subscription Revenue = New Subscription Revenue + Renewal Revenue
Total Subscription Revenue is not a seventh event. It is an analysis metric that brings together the value from a user’s first payment and the value from continued payments.
This distinction is useful in practice. New Subscription Revenue helps identify campaigns creating immediate paid value. Renewal Revenue shows which campaigns are creating durable value. Looking at the combined figure lets teams compare the total subscription revenue generated by campaigns, channels, Product IDs, or markets instead of optimizing solely for first-time conversion.
It also gives better context for spend decisions. A campaign with a higher CPI or cost per trial may still be more efficient if its subscribers generate stronger total subscription revenue over time.
How to Measure Subscription Revenue by Campaign
An MMP’s job is to connect downstream outcomes to the activity that acquired the user. For subscription apps, that means bringing trial, subscription, renewal, cancellation, and revenue data into the campaign reporting used for UA decisions.
Tenjin’s native iOS Subscription Revenue Report connects the six subscription metrics to the campaigns that brought users in. It works alongside RevenueCat and Adapty integrations, so teams can analyze New Trials, New Subscriptions, New Subscription Revenue, Renewals, Renewal Revenue, and Cancellations alongside attribution and spend data.
That enables more useful questions than “Which campaign drove the most installs?”
Por exemplo:
- Which channel drives the most New Trials, and which drives the most New Subscriptions?
- Which campaign brings in subscribers who renew?
- Are cancellations concentrated in a particular source, audience, or offer?
- Which Product IDs generate more new and renewal revenue?
- Which campaigns generate the most Total Subscription Revenue after acquisition costs are considered?
The point is not that every campaign will show the same lifecycle on the same day.
Trials, conversion, renewals, and cancellation behavior happen over time. Teams should compare performance over a window that reflects their trial length and billing periods, rather than treating same-day totals as a complete conversion rate.
Perguntas frequentes?
No. Freemium provides ongoing access to a free version of an app. A free trial provides temporary access to premium features before a potential paid conversion.
Yes. An app can give users a permanent free tier and also offer a time-limited trial of premium features. When the trial ends, the user can return to the free tier or continue with a paid subscription.
New Subscriptions are first-time paid subscriptions. Renewals occur when an existing subscriber continues into another billing period. Together, they show initial conversion and continued subscriber value.
New Trials, New Subscriptions, New Subscription Revenue, Renewals, Renewal Revenue, and Cancellations provide the core lifecycle view. Combine new and renewal revenue to evaluate Total Subscription Revenue by campaign.
Choose the Model You Can Measure
Free trials, freemium, and paid subscriptions are not competing labels for the same thing. They create different product and acquisition journeys, each with different points at which value becomes visible.
The best model for your app should fit the product’s recurring value and give users a clear reason to pay. The right measurement should show whether the campaigns acquiring those users create trials, paid subscribers, renewals, and revenue that lasts.
