When Apple’s iOS 14.5 update landed in April 2021, it rewrote the economics of mobile app growth. The update’s App Tracking Transparency framework effectively killed user attribution for mobile marketers, leaving app developers scrambling to understand which campaigns drove downloads and purchases.

Three years later, a new industry has emerged from that chaos. Companies like FunnelFox are helping mobile apps bypass Apple and Google’s app stores entirely for subscription revenue, routing users through web-based payment flows that save millions in commissions while restoring the attribution data that iOS 14.5 took away.

The anatomy of web-to-app

The concept behind “web-to-app” is elegantly simple. Instead of driving Facebook or TikTok ads directly to app stores, marketers route traffic to mobile-optimized web pages that mirror their app’s onboarding experience. Users complete surveys, interact with app functionality, and most importantly, purchase subscriptions directly on the web before being redirected to download the app.

“Usually app marketers run traffic through paid user acquisition channels like Meta, TikTok, Google directly to app stores,” explains Andrey Shakhtin, CEO and Co-Founder of FunnelFox, in a recent interview with Business of Apps conducted by industry veteran David Murphy. “The release of Apple’s iOS 14.5 update in 2021 dealt a massive blow to both ad campaign performance and user attribution efforts.”

The future of web-to-app funnels for app growth

 

The web-to-app approach solves two critical problems simultaneously. First, it restores complete attribution data, allowing marketers to optimize campaigns with the precision they enjoyed before iOS 14.5. Second, it eliminates Apple’s and Google’s commission structure, which ranges from 15% for smaller developers to 30% for larger ones, replacing it with standard payment processing fees of 2% to 5%. Web-based subscription flows also offer payment flexibility that app stores simply cannot match.

The infrastructure challenge

The shift from app store to web revenue requires rebuilding core business infrastructure. Apps moving subscription revenue to the web must suddenly handle refunds, tax calculations, payment disputes, chargebacks, and subscription management — functions that Apple and Google previously managed.

“The App Store took care of all this stuff on behalf of developers,” Shakhtin notes. “Shifting your purchases from the App Store to web leads to a lot of additional things that you need to take care of.”

This complexity explains why FunnelFox’s recently launched billing infrastructure has become crucial for the company’s 500-plus app clients. The platform’s payment orchestration system routes transactions between multiple payment providers based on factors like user location and card type, while automated recovery systems save an average of 20% of failed payments.

“The App Store took care of all this stuff on behalf of developers. Shifting your purchases from the App Store to web leads to a lot of additional things that you need to take care of.”

Perhaps most importantly, the system includes what FunnelFox calls “subscription cancellation flow”, customizable retention experiences that can save up to 30% of revenue that would otherwise be lost to churn. Unlike Apple’s restrictive cancellation process, web-based flows allow developers to survey departing users, offer win-back discounts, and implement sophisticated retention strategies.

The conversion optimization edge

The data emerging from web-to-app implementations reveals significant performance advantages over traditional app store funnels. FunnelFox’s pre-designed checkout flows demonstrate conversion rates 20-30% higher than default payment provider interfaces, while the company’s no-code funnel builder allows marketing teams to launch experiments without involving development resources.

“You can set up experiments and get web-based changes in the marketing team itself without support from product or technical teams,” Shakhtin explains.

This experimentation velocity has driven a new trend: multi-funnel strategies. Instead of funneling all traffic through a single conversion path, successful apps now deploy multiple funnels targeting different user segments. One fitness app client, previously operating a single funnel, now runs ten distinct funnels for different user types.

“More and more companies started launching multiple funnels for specific user segments,” Shakhtin observes.

AI meets human creativity

Looking ahead, FunnelFox is betting on AI-assisted funnel generation while maintaining human creative control. The platform’s AI tools can generate production-ready funnels based on prompts, allowing marketers to rapidly test concepts across different audience segments.

But Shakhtin emphasizes that creativity remains fundamentally human. “Creativity is still coming from people,” he says. “I see it as a combination of people creativity and AI automated operational stuff.”

The Apple policy wild card

Apple’s recent policy changes allowing external payment options could accelerate web-to-app adoption. While developers must still pay Apple a commission on external payments, the reduced rate and increased payment flexibility make web-based revenue streams more attractive.

“I think it’s great momentum for the whole industry to shift strategies from App Store-only for distribution and monetization to web and other external options,” Shakhtin argues.

Industry observers suggest that web-based revenue is already becoming dominant for companies that have implemented web-to-app strategies, with marketing budgets increasingly allocated to web channels rather than traditional App Store acquisition.

The path forward

For app developers considering the transition, Shakhtin’s advice is unequivocal: prioritize experimentation speed over building internal infrastructure. “Don’t use your in-house solutions because it’s slowing you down,” he warns. “Use proper tools to experiment faster and grow faster.”

The web-to-app revolution represents a fundamental restructuring of how mobile apps generate revenue. As attribution challenges persist and commission costs remain high, the companies that master web-based subscription flows may find themselves with sustainable competitive advantages that extend far beyond simple cost savings.

In an industry where iOS 14.5 seemed to level the playing field by limiting everyone’s attribution capabilities, web-to-app has emerged as the new differentiator, separating companies willing to rebuild their growth infrastructure from those content to accept the limitations of dependency on Apple and Google.
