Free trials fail when people forget they signed up and get surprised by a charge.
For this app, I designed a transparent trial to paid flow. Before checkout, users see exactly what happens on day 1, day 6, and day 7, so nobody feels tricked when the charge hits.
I also worked on the paywall itself: clear benefits, a highlighted pricing tier with a visible discount, and a personalized avatar step earlier in onboarding to build identity before the ask.

Turned a 20 question assessment into something people actually want to finish.
For this elearning platform, evaluation needed to feel less like a test and more like a game. A friendly mascot sets the tone, wrong answers still have personality, and instant feedback turns every miss into a quick lesson.

Reacting to a WhatsApp Status is too easy to do by accident. The emoji bar sits right next to the reply field, so a misplaced tap sends a reaction instantly, no confirmation, no easy undo.
Fix 1 — a cancel window. Tap an emoji and a 3-second countdown with a cancel button appears before it sends. Let it run out and the emoji bursts off to the profile icon, confirmed. Cancel, and it animates back, nothing sent.
