Blockr

VP of Design / Founding Product Designer | 2024

Spam Texts, Blocked Before They Reach You
Blockr was built fast—from zero to App Store in just a few weeks. As the Founding Product Designer and VP of Design, I led end-to-end product and brand development for this AI-powered text blocking app, focused on a younger audience fed up with spam texts cluttering their inboxes.



The Problem
Americans receive up to 40 spam texts per month, and text scams cost victims an average of $1,000 per incident. Younger users, who often ignore spam calls entirely, are increasingly vulnerable to messages that slip through. Blockr was created to solve that—simply, playfully, and fast.



My Focus
As a one-woman design team, I led all design and creative direction across product, brand, and marketing. My work spanned from initial concept to final App Store launch in under five weeks:
  • Designed the full app experience—from onboarding to keyword pack selection to paywall and settings
  • Created a visual language that felt bold, playful, and modern—targeted toward a younger demo without sacrificing trust
  • Invented “Keyword Packs” as a user-friendly layer over traditional block lists, powered by AI-suggested filters
  • Explored gamification features to incentivize user-submitted spam texts (deprioritized for MVP)
  • Led creative across channels including App Store screenshots, email flows, landing page design, and blog templates


Outcomes


Early traction and conversion rates exceeded App Store benchmarks:
  • 🚀 Install to Paywall View: 68% (vs. App Store avg. 53.5%)
  • 💳 Paywall View to Purchase: 15% (vs. App Store avg. 7%)
  • ✨ Install to Trial Conversion: 12% (vs. App Store avg. 3.5%)
