#232: Mobile app paywalls & cognitive biases with Max Amelang, Product Marketing Manager at Prematch
One of the most important metrics for a mobile app is its conversion rate. It tells you how many people that use the app for free become your paying customers. It’s about how profitable and sustainable your app is.
Now, if you are one of the die-hard Pink Floyd fans, you gotta love their song The Wall. If you are an app marketer, your wall is the paywall :-) Among many tools that you may use to increase the number of people who become your paying customers, once they hit the paywall, are cognitive biases.
You may heard of them if you have a peripheral interest in psychology.
Today, Max will tell you about using cognitive biases to significantly increase your app’s conversion rate.
Today’s topics include:

Quotes from Max Amelang
"Yeah, it's absolutely a valid question because especially in the beginning, it's extremely tempting to see all of these tools you can use to somehow increase this conversion rate by margin or by another percent and so on. But then I also quickly realized not only as a product manager, but also as a user, how would I feel if I stumble across this? "
"Obviously I know the tricks, so maybe I need to be a bit harder in order to define if something is good or not so good anymore. And I then came up with like, how would my parents behave on this paywall? Because parents just as a symbol for an older generation that are not as native with mobile apps.
And I always am fascinated when I see how my dad navigates his app and when I realize, why did he just click on this button because it's blinking quicker? And I realized, okay, this is how easily he's influenced. So as a very soft first test, I'm thinking about, okay, how would my dad would behave on this paywall? Would he buy just because of the cognitive biases or would he still be able to make his own decision?"

#231: Beyond behavior: unlocking intent with on-device AI with Dieter Rappold CEO at ContextSDK
Ok, here is the thing.
Most apps are still built on rigid, one-size-fits-all user flows. They rely heavily on historic behavior - what a user clicked on last week or which segment they’re in. But user needs change moment to moment. And when apps fail to adapt, users just leave.
The next evolution isn’t about personalizing based on identity - it’s about adapting based on intent. And that intent can only be accurately understood in context.
In this episode, we’re going to talk about the Context Platform by ContextSDK that enables apps to detect real-world context in real time - whether a user is walking, relaxing, commuting, charging their phone, or simply on the move - and then infer their intent. Using a combination of on-device machine learning and server-side intelligence, the platform helps apps deliver the right experience or message at the right moment.
This isn’t just a UX upgrade - it is a fundamentally better way to retain users and drive revenue, while respecting privacy and improving performance.
Today’s Topics Include:
Dieter Rappold's' bio
About ContextSDK
Switching focus from app users' behavior to their intent
How Context Platform helps LiveOps maximize their efforts
Example of how detecting user context in real-time improves the app experience
How context-aware delivery fix the issue with intrusive push notifications
Achieving personalization without relying on personal data or permissions
What it takes to implement Context Platform into the app

Quotes from Dieter Rappold
"It’s great to know a lot about past behavior, but past behavior is looking into the past. Intent is happening in the moment and is looking forward"
"We collect enough data points on patterns of movement and behavior and analyze them with the smartest machine learning models out there. That allows us to infer intent—and that’s something extremely powerful when shaping app experiences,"

Quotes from Andy Willers
" What AI has allowed us to do, particularly on the UGC side, is massively increase our capability for creative testing,” Andy said. “HeyGen’s digital avatars enable us to quickly generate multiple UGC scripts or executions—allowing us to test different messaging and ad styles at scale.."
"We’re not at a stage where you type in a prompt and AI spits out a perfect execution. The human touch is still essential,” he explained. “HeyGen gives us the raw material—high-quality AI avatars—but it still requires skilled video editors to integrate them effectively with B-roll footage and visual elements."

#225: Driving App Growth with A/B Testing with Tina Kim, Director of Product Management at Huckleberry Labs
Today, we begin with another trivia question for you - can you think of the best case for A/B testing? Are you thinking about a particular app, service, or product?
No - it’s bigger than that, I’m talking about the evolution of life on this planet. No, there is no a girl or a guy, sitting with a MacBook Pro and running A/B tests for all flora and fauna on this planet :-) My point is that testing is very fundamental and, if it will make you feel a bit more important, you’re doing it along with the Mother Nature.
To talk about A/B testing for driving app growth we invited Tina.
Today’s Topics Include:

Using A/B tests to make confident decisions

Quotes from Tina Kim
" So A-B testing is really useful for when there is a shadow of doubt. Put it so whatever you A/B test, it's not some idea that you've picked from the air. It's always based off of some well-informed hypothesis, whether it be analyzing your behavioral data of your users or you've done some user research market research as well. There is always some well-informed hypothesis that drives you to build something."
"The other thing is where A-B testing can really help you move forward faster is during the development process, the design process, there may be countless arguments about the perfect copy. Some people are very particular about copy, but and we may spend like endless cycles just trying to perfect the copy, but that's not the point of the change. Let's just test it. And A-B testing is iterative. And so you find something that you feel good with, it doesn't have to be perfect, and you test it and move forward. And if you feel like there's opportunity to squeeze more juice, test it again, right? And so I've been able to move forward faster."

#224: Breaking down the Subscription Value Loop strategy with Phil Carter, Growth Advisor at Elemental Growth
In the future, history textbooks will be telling the story of how, at the beginning of the second decade of the 21st century, we all collectively jumped into the world of mobile apps.
Now, you may be super excited about the growth of the mobile ecosystem or shake your head about its externalities, unintended consequences, but it’s undeniable - mobile apps take a huge spot in our lives.
Today, a big chunk of the mobile app economy space belongs to app subscriptions - Netflix, Apple TV, Tinder, Duolingo, the list goes on and on. If you build apps yourself and monetize them with the subscription model, you will be really interested to learn about Phil’s Subscription Value Loop strategy.
Today’s Topics Include:

Quotes from Phil Carter:
"The core of the subscription value loop framework that I teach about in my course is a company's core value promise. In other words, what is the value that you're providing to a user, and ideally to a paying subscriber, that is going to not just bring them to the product in the first place, but cause them to continue paying you a subscription over a long period of time?"
"And value delivery is typically led by marketing teams, sometimes with the support of growth product teams or sales teams if you have a B2B business. And value delivery is all about making sure that you have sustainable unit economics, right? You're going to have some amount of LTV that you get from users. But in order to have a sustainable business, you need a strong LTV over CAC ratio and a rapid payback period. And that depends critically on your cost of user acquisition."
