Is there a demand for niche apps regarding emotion-focused digital legacy?

Hi everyone! 👋 I'm FarLee_70s, the maker behind KeepBridge.

In 2014, MH370’s disappearance made me think about unspoken words.

Years of solo travel and life’s uncertainties deepened that question:

What if we could leave reassurance, even when we’re not around? 😔

I’ve been a computer enthusiast since the DOS days in the early ’90s.
In this AI-dominated tech wave, choosing simple technology for a profound meaning feels like a middle-aged uncle’s sentiment. 🤓

In 2025, when my daughter graduated from college, we decided to build something human - KeepBridge, a small "control tower" for life.

✈️ How it works
Based on a simple check-in (like a plane’s ping to the control tower), KeepBridge has 3 key functions to help deal with life’s uncertainties.
Here’s how I use them:

🕰️ Time Capsule — Stores messages like:
“My seed phrase is in the dictionary on the bookshelf.”
No sensitive info online, just instructions for offline secrets.
Messages are delivered if I miss a long-term check-in (300 days).
As a BTC holder, it’s my last line of defense. If something happens to me, it guides my daughter to find my things. 🔑

⛄ Keeper’s Watch — I live alone in the countryside.
If I miss a 72-hour check-in, my brother gets an alert. 🚔

🛵 Guardian Me — For solo motorcycle trips, I set a short countdown (e.g., 4 hours).
It’s like buckling up before I ride out.

BTW: Earlier this year, a woman in Indiana was stranded in her car for nearly a week after an accident. If she’d had something like this, help might have come much sooner. 💔

💬 Looking for advice from fellow makers
I don’t have a marketing team or big social reach — it’s just me (and my daughter) building this from our kitchen table.

We’re preparing to launch on Product Hunt, but I’m still figuring out how to make it visible as a small indie project.

I’d love to hear your thoughts:
– Does this idea make sense to you?
– Would you or someone you know actually use something like this?
– Any tips for a first-time PH launch?

Every bit of advice or encouragement helps more than you know. 🙏
