Thanks, you had a good eye for that! Will change it...

Hi HN!

I started working on Fantasy Walk about three months ago. I built it for people who love fantasy RPGs and need a little extra nudge to get outside and walk more often.

The core loop: - Pick a character - Your real-world steps advance you on a fantasy map across different villages - Along the way, you discover creatures, complete quests, and fight battles

Combat (Steps vs. Heart Rate): For combat, I decided to offer two different approaches: you can fight either using your step count or using your heart rate. My personal theory was that the heart-rate option would finally trick me into doing more cardio workouts. Well... it didn’t work on me at all. But maybe someone else will find it motivating!

Monetization: I initially set up the additional content as a monthly subscription, but quickly realized that was premature. I haven’t implemented features that actually justify a recurring fee (like competitive ladders or multiplayer events, which only make sense with a large user base anyway). So I scrapped the subscription and made the extra content a simple one-time purchase.

Tech & How it was built: - Stack: Built with Flutter for Android. - Experience: I’ve been programming for about 20 years and have been working with Flutter pretty much since its early beginnings. - Step Tracking: Syncs steps via Google Health Connect - easiest way for now - AI-assisted development: Even with my background, building an entire game solo — from mechanics to assets and integration — is a massive undertaking. I heavily paired with GPT models throughout the process. Honestly, without AI as a multiplier, I never would have tackled a project of this scope on my own. - Along the way, I created my own skills for Flutter layouts and architecture. It took quite some work at the start, but now it works good. I wanted it to look like my own code, so I can easily navigate and fix things if something goes wrong. (or at least understand why things goes wrong)

That’s about it. I still have a long list of ideas I want to implement, and I hope some of you find the idea and its execution fun and worth checking out.

Yes, thats what i meant. I will definetly Play around with that idea..

Yes, you can export and import the data in the app

There are ways to check what data is send trough the network...

Good point - I changed the description!

Nice to hear - I googled your watch and wrote you a DM on instagram

My app needs a minimum sdk 19. So at least that would fit. But to be honest: I don't think I'll add those features in the near future. The mood tracking is already on the feature list. But the one with the tags.... I write it down to evaluate it. Also you can export the data - but that will result in a json file - not a csv

Yeah - you are right. But I like it that I can see how many days are left - even if it's not 100% correct and I get stuck at "5 minutes before 12" because then I see that it can appear every time. Maybe I'll add an option for another representation... something like the commit graph in github (don't know the name...) That would be nice too.

To compare the cycle length there is an extra statistic section. I want to add a graph there to make the fluctuations more clear.

Thank you for your positive comment. I really appreciate that – the topic of women in the tech industry is particularly close to my heart!

I wish you and your family all the best – you made my day :)

Thanks - that was my previous app too ;)

Thanks! The backup feature is already on my roadmap to offer it as an optional feature - but since you can manually import and export your data, it's not a high priority yet. F-Droid may be an option - but for now the project is not open source. so I think that's not possible

I'm not planning on that at the moment. The next feature is a graphical representation of the period duration. But I added this on my list

Thanks!

In-app purchases: You can buy another theme if you want. There is no need to do that - the whole functionality is available anyway. I thought it would be nice to at least have the opportunity to make some money from it...

I haven't thought about open-sourcing it... Maybe I'll think about it...

I use GA only for the homepage not the app itself
