I replaced paywalls with an "Energy" system in my travel app. Is this a good idea?

Hey everyone! 👋

I'm a solo dev launching my first app, Yatavi, tonight. I built it because I was frustrated that every decent travel planner charges an expensive monthly subscription just to use basic maps or add multiple stops.

I decided to make Yatavi completely free without forced paywalls. Instead, I implemented an "Energy" system (similar to mobile games). Users can access all premium features by watching a voluntary rewarded ad to refill their energy.

Since this community knows a lot about SaaS and app monetization, I’d love your honest observations and feedback.

Do you think this gamified model works better for B2C travel apps than traditional subscriptions? What improvements or blind spots should I look out for?

I'd love to hear your thoughts! 🚀
