Hello HN,I basically don&#x27;t use notifications for anything. The noise is too much. Slack is too loud. Email is too slow. But sometimes you do need a note in your face.I found myself missing 1990s pagers. I wanted a digital equivalent - something that does one thing: beep until I ack it.So I built UDP-7777.Concept:- 0% Cloud: It listens on UDP Port 7777. No accounts, no central servers. You don&#x27;t need Tailscale&#x2F;ZeroTier&#x2F;WG&#x2F;etc, it&#x27;s just easy for device sets.- CAPCODES: It maps your IP address (LAN or Tailscale) to a retro 10-digit &quot;CAPCODE&quot; that looks like a phone number (e.g., (213) 070-6433 for loopback).- Minimalism: Bare-bones interface. Just a box, a few buttons, and a big red blinker.The Tech:It&#x27;s a single binary written in Go (using Fyne). It implements &quot;burst fire&quot; UDP (sending packets 3x) to ensure delivery without the handshake overhead of TCP.New in v2.2.7:- Frequency Tuning: Bind specifically to your Tailscale&#x2F;ZeroTier interface.- Squelch: Optional shared-secret keys to ignore unauthorized packets.- Heartbeat: Visual&#x2F;Audio alerts that persist until you physically click ACK.I built this for anyone looking to cut through the noise—DevOps teams handing off the &quot;on-call IP&quot;, or deep-work focus where you only want interruptions from a
high-trust circle.I&#x27;d love to hear your thoughts on the IP-to-Phone-Number mapping logic (it&#x27;s purely visual, but I&#x27;m really into it).Site &amp; Binaries (Signed for Mac&#x2F;Win): <a href="https:&#x2F;&#x2F;udp7777.com" rel="nofollow">https:&#x2F;&#x2F;udp7777.com</a>

I’ve been working on a small language learning app as a solo developer.I intentionally avoided gamification, streaks, subscriptions, and engagement tricks.
The goal was calm learning — fewer distractions, more focus.I’m starting to wonder if this approach is fundamentally at odds with today’s market.For those who’ve built or used learning tools:
– Does “calm” resonate, or is it too niche?
– What trade-offs have you seen when avoiding gamification?Not here to promote — genuinely looking for perspective.

Ask HN: Is building a calm, non-gamified learning app a mistake?
