Has anyone implemented a gamification system in their non-gaming app?

no am not

Would you consider something like a credit program under gamification? https://www.rock.so/help/credit-...

We have not exactly implemented a gamification system in our product. What we did was to host an interactive online puzzle game which was tied with social media as well, with prizes which required players to log in to the system for free (limited access to puzzle elements). In addition, you may use the system to host or organize online role playing games, which I think is a nice touch despite not being developed with that purpose in mind.

This is something I am looking at currently so curious to see the responses

Forest app helps users stay focused by planting a virtual tree every time they avoid using their phone for a set period of time.

One example of a non-gaming app that has implemented gamification is the productivity app Forest.

I haven't implemented it for myself but as a marketer I have implemented it for my clients and they have got great results Leading to increased engagement and Customer loyalty among the users

Im actually launching a blockchain-powered loyalty and retention app designed to help creators and businesses easily build branded engagement programs to increase customer retention and drive growth. There will be multiple avenues for gamification. To top it off, we removed all the friction of interacting with web3 so everyone gets to experience a fun, simple app. Won't add anymore spoilers here 🤫
