Hey Stackers,
Built this for my family to track our Bitcoin stack without trusting a third party with our data.
Key features:
- Client-side encryption (your balances never leave your device unencrypted)
- Sign in with nsec (no email required)
- Power Law price model - see where your stack could be in 5, 10, 20 years based on the model
- Track-It portfolio projections show your holdings plotted against the Power Law curve
- Find merchants to spend sats within 100 miles (circular economy!)
- Bitcoin-backed loan calculator
iOS TestFlight beta: https://testflight.apple.com/join/zp3DtMVb
Web app: https://neversellyourbitcoin.live
Would love feedback from the SN community. What features would you want to see?
bitcoin way to sign up or sign in would be nostr
It's nsec/npub under the hood. Kept the branding "Bitcoin Way" to stay accessible, but Nostr users will feel right at home.
actually using "bitcoin way" instead of nostr is great. but i would prefer not to enter my nsec, let me use a browser extension instead
I've gone ahead and added teh browser extension. Thank you for the feedback @nathanael !
I'm curious how you personally use the app. You add all your balances and track it over time? Then you look for merchants to spend it and calculate loan returns with it?
I have friends that do this in spreadsheets, so I imagine one could use this as a specialized spreadsheet. It looks like you're creating a one-stop-shop app though with a lot of other things it does.
Exactly right. I add my accounts on Stack-It (date, amount, price - all encrypted), and Track-It shows my total stack with cost basis and unrealized gains plotted against the Power Law.
You can also upload DCA buys from your monthly exchange PDFs/CSVs - it parses them and tracks the gains for each buy over time. Great for seeing how your oldest sats have performed vs recent buys.
Spend-It pulls from BTCMap so I can find places to spend locally instead of selling. My daughter and I were in Vermont the last few days skiing and found BTC-friendly spots, np.
I actually started with a spreadsheet as well. This is basically that spreadsheet evolved, with Power Law projections, merchant map, and the ability to share encrypted accounts with family members so we can track our stacks together.
I see.
What is the one essential problem the app solves? If you had to remove all features except the features helping solve the one essential problem which features would be left?
If I stripped it down to one thing: seeing your stack projected against the Power Law model. When you can visualize where your sats could be in 10-20 years, you stop thinking about selling.
And when you stack more, you watch milestones like a $1M stack value get pulled closer in time. That makes the price swings way easier to stomach - you're focused on the destination, not the turbulence.
Everything else - the merchant map, loan calculator, family sharing - exists to give you alternatives to selling when you need liquidity or want to use your Bitcoin.
The name says it all: Never Sell Your Bitcoin.
