I can’t believe it! 👀 While on vacation, I checked my phone and saw 2 notifications My first 2 PAYING customers and even a $99.99 yearly trial conversion 🙌 All of this just running Apple Ads for Witsy with $5/d This is the moment I have been building for

Just got my new version approved 🎉 Spent the last week refining the onboarding and paywall 2 weeks of running ads resulted in a large number of completed onboardings BUT not a single trial conversion in the last 2 weeks ❌ My theory: Users do not know what they are paying for until after the paywall 👀 Let‘s see if things will change Demand is there, just need to nail the execution 🙌

2 weeks of running paid Apple Ads, these are the stats 🎯 Spent 80€ 💰🔥 - 100 active customers - 38 onboardings completed - 2 trials (both cancelled) Still at 0€ and honestly feeling a bit frustrated. BUT I will keep going until I get the first paying customer 💪 Working non-stop on improving my features and fixing my onboarding & paywall.

Another 5 installs in the last 2 days! 🎉 Instead of focusing on only organic marketing, I set up my first app store ads on Friday and started running them. The results so far: → 500 Impressions → 20 Taps → 3 Installs (all finished onboarding) It's crazy to think that people chose my app over competitors doing over $1M in monthly revenue 🤯

3 weeks ago I released my app Witsy, it's still at $0 MRR But I can finally see something moving, 40+ page views yesterday → 6 installs! 🎉 Crazy what posting on TikTok and some ASO can do It gives me hope for getting my first customer soon. Not giving up until then 💪 Persistence is key

Witsy just got a major update and it got approved right away! 🎉 The biggest change: the UX I was able to cut down on a lot of complexity by removing some screens entirely or merging them together. Now: - More screens are showing the mascot - Onboarding feels more personalized - Added a cute Streak Screen I feel excited because finally the design feels more coherent. Only one issue: Still at $0 MRR 👀
