Question: Is there a platform that offers a simple way to implement streaks, XP, and levels in my app without building from scratch?

If you need a service to build streaks, XP and levels into your app without having to reinvent the wheel, Gamify Everything is a good option. This API-based service lets developers add gamification features easily with streaks, XP and levels, punch cards and in-app currency. It's designed to keep people engaged by tracking progress and automatically leveling up, and it's easy to integrate with API calls. It's got a variety of pricing tiers and a seven-day money-back guarantee, so it's a good option for developers who want to keep users engaged without gamification features they have to build themselves.

Another alternative is Noodl, an open-source low-code platform that makes it easier to build custom apps. It's got a lot more features, including AI-assisted development and real-time data flows, but it also can be used to build gamification elements like streaks and levels in a visual programming environment. It's good for developers of all skill levels, with lots of documentation and community support.

Noodl is particularly useful if you want to build gamification into a larger, more elaborate app. Its flexibility and expandability could be useful if you expect to expand your app a lot. But if your first priority is just a simple gamification mechanism, Gamify Everything is probably a better choice.
