Totally agree! Bouldering outdoors is a completely different vibe. But if you want to train for your outdoor projects, you might wanna try nprofile1qqswwksctsqe6zgyn40ukr3f5txfhlgpdmq0dkyjljv0dllqrqdysrgpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsz9nhwden5te0wfjkccte9ejxjar5duh8qatz9uq3uamnwvaz7tmwdaehgu3dwp6kytnhv4kxcmmjv3jhytnwv46z7s88teg (nprofile…8teg), which is my Nostr native Kilter board app 😉

Vielen dank an euch und natürlich auch Egge (nprofile…vcku), Max (nprofile…en87) und Thomas (nprofile…ejmy) für das spannende Gespräch und dafür, diesem wirklich coolen Projekt eine Plattform zu bieten! Ich werde es leider nicht schaffen, mir 6 Wochen freizuschaufeln, aber ich bin gespannt, was aus der neuen Kohorte wieder an Projekten rauskommen wird.
Und ich bin gespannt, ob/wann sich Souvereign Engineering tatsächlich dezentralisieren kann. Bei einer Souvern Engineering Alps Edition wäre ich auf jeden Fall dabei😉

Looking forward to it :)

Good point. I guess YouTubers should be able to mirror their own videos to Blossom with one click. And auto-upload to Nostr when they post new videos on YouTube.

Of course it would be great, if we have much more videos on nostr, but I guess it would be to expensive to mirror just more or less all videos. Would be interested in your opinion on how well Nostr/Blossom scales regarding data growth.

Trying to do the same with the official Kilter Board App, I am trying to provide a better alternative to. At least sync from the offical app to CruxCoach/Nostr and opt in sync from CruxCoach to the official Kilter App if the user does not want to leave the old world completely.

CruxCoach v0.1.3 just shipped — Nostr backup is now live!

Backup your climbing history and restore on new devices, end-to-end encrypted:

- 🔐 AES-GCM blob on Blossom
- 📍 Kind 30078 pointer (NIP-44 self-encrypted)
- 🔑 Your `nsec` is the only key to restore the backup

No accounts. No provider lock-in. Restore anywhere.

Also in this drop:

- ⚡ Quick-Send: 1-tap connect → send → auto-disconnect
- 🧗 Multi-frame routes play correctly again

Congrats on the rewrite!

For those shipping Android apps from a NIP-34 repo to Zapstore (nprofile…gsu4) What's the current best practice?

As far as I can tell `zsp` doesn't auto-detect `nostr://` / gitworkshop URLs yet, so the options seem to be: point `repository:` at the underlying git server (Gitea/Forgejo/Codeberg) or just hand `release_source:` a direct APK URL.

Is that the right path? Any plans to make nostr-native repos a first-class source? 👀

2026-04-24T10:08:16Z

The official Kilter Board app requires Google Play Services. It ships with Firebase Analytics, a Google Places API key, and a mandatory Kilter Board cloud account just to browse climbs.

CruxCoach ships with zero Google dependencies.

• Runs natively on GrapheneOS, CalyxOS, LineageOS, /e/OS
• Board data via Nostr + Blossom, not cloud sync
• No accounts, no telemetry, no tracking
• Works offline after initial database download

Thanks for the mention! Climbing app on the surface, but Nostr is most of the plumbing underneath:

• Keypair identity — no accounts, no email
• NIP-17 encrypted DMs for bug reports + feature requests, right from the app
• Blossom for distributing the public 85k-climb database — your ascents and logs stay on device

Encrypted cross-device backup over Nostr is on the roadmap. Zapstore was a natural fit. Feedback and Feature Requests always welcome.

Well that makes two of us 🤝 Now we just need to clone ourselves at the board.

Actually, there's a path for that without Zapstore in the loop: v0.1.1 ships Local App Share — your phone becomes a WiFi hotspot + download page, your climbing partner scans two QR codes and has the app + the full 137 MB Kilter DB in under a minute. Zero internet, zero gatekeepers.

📱 How to share CruxCoach locally — zero internet required:

1️⃣ Settings → tap the share icon in the top right.

2️⃣ Pick "Share locally (WiFi Direct)". Your phone opens a
local hotspot + download page. Nothing leaves the gym.

3️⃣ The other person scans QR #1 to join your hotspot, then
QR #2 to open the download page.
⚠️ Turn mobile data + VPN OFF on the receiving device,
otherwise traffic won't route through the hotspot.

4️⃣ Download & install the APK (allow "Install from unknown
sources" if prompted). Then tap the green import button on
the download page — the app opens and imports the 137 MB
Kilter DB straight from your phone. No second download.

🪨 CruxCoach v0.1.1 is out!

Headline fix: Local App Share now works end-to-end.

No internet. No Play Store. No app-store gatekeepers. No data
plan. Your phone becomes a WiFi hotspot + local download page —
hand the app (and the 137 MB Kilter climb database) to a mate
at the board in under a minute. Perfect for gyms with zero
reception, trips abroad, or onboarding a new climber on the spot.

In 0.1.0 the receiving device couldn't import the shared climb
database. That's fixed now — no more 100 MB Kilter-DB downloads
for every new user.

Also in 0.1.1:
• Progress bar stuck at 0% during initial board import — fixed
• Crash on older devices with large DBs — fixed
• Splash logo invisible in light mode — fixed
• Move count for boulders, frame count for routes
• Onboarding skips download if the DB is already there
• APK + release notes on Codeberg (no more Zapstore-only)
