[Tool] btcprice.app - private crypto portfolio tracker, no wallet connection

Hi everyone,

I built https://btcprice.app/ because I missed the simple "open it and see what you own" feel of the original Blockfolio app.

It is a manual crypto portfolio tracker for long-term holders. You can add holdings from exchanges, software wallets, hardware wallets, or anywhere else as separate entries, then see the total value, allocation, and estimated profit/loss in one place.

The goal is to keep it useful without turning it into a trading terminal.

Current features:

• No account or login required
• No wallet connection, exchange API link, signing request, or custody
• Portfolio data stays in your browser
• Market data and asset discovery from CoinGecko
• Separate entries for the same asset, with optional labels and cost basis
• Combined portfolio value and allocation
• Private mode to hide balances and quantities
• Portfolio backup and restore
• Shareable portfolio image cards
• Dark and light mode
• Optional gold, silver, platinum, and palladium tracking
• Asset search beyond the visible top-market list

It is intended more for people holding crypto across multiple places than for active traders. For example, you can keep separate entries for BTC on an exchange, a hardware wallet, and a software wallet, while still seeing one combined total.

I'd appreciate honest feedback, especially from people who used the original Blockfolio:

• What did Blockfolio get right that current trackers tend to miss?
• Which features here feel useful versus unnecessary?
• Is anything confusing or missing from the workflow?
• Would you prefer manual tracking like this over connecting wallets and exchanges?

This is an independent portfolio-tracking tool, not a wallet, exchange, broker, or financial adviser.

Never used Blockfolio, but get your site listed here for better exposure:

I tried making some random portfolio, download the backup (for some reason it's a png?) and tried to restore it. It seem like it doesn't even detect the backup file properly, if that's even supposed to work. For the record, I used a Chromium based browser on a Mac to test this. Is the feature still not yet live, or does it requires specific setups? I thought the backup would be a json file or something similar instead of a PNG image.

Thanks for the testing! I fixed this last night before seeing this post. Should be good now. I don't think many people would use this in the beginning and/or unless they know they are switching devices and have a large list of coins they are tracking.

It was just saving the wrong extension type wrong, if you open that .png in notepad you would see the json text.

Thanks vod. I tried to post it https://www.reddit.com/r/CryptoCurrency/ but keeps getting flagged. I'll take a look at that site and post it there, but maybe after the android app is published, just need to wait 2 weeks for google to approve it.

The OG Blockfolio app was really simple with no logins or anything, good for long-term holding I would put my coins that i have on ledger,metamask,coinbase, etc in there to track it in a single view. Then FTX bought it and they began using it to funnel users to ftx.com and the FTX app.

I see you are using coingecko data, and I think they also have some kind of portfolio tracker available.
Back in the old days I was testing several portfolio tracker, but none of them meet my strict criteria.
There was one app called Rotki that was open source, and you could download it and use on your computer.
Everything else, inlcuding OP app, is web version and I don't know who is collecting information I enter with my IP address.

Thank you for bringing this u, it’s a fair concern, and I appreciate the question.

I’ve updated btcprice.app’s Privacy Policy to explain exactly how it works: positions, amounts, optional buy prices, Watchlist items, and preferences are stored locally on the user’s device. The app does not require wallet connections, message signing, or accounts, and I do not run a portfolio database or store user balances.

I also clarified that CoinGecko’s CDN and Coinbase live ticks may process normal connection metadata such as an IP address. They do not receive portfolio balances, amounts, totals, buy prices, wallet credentials, or private keys. CoinGecko price requests identify requested assets, not how much anyone holds.

I’ll keep working on ways to reduce third-party exposure further, and I intend to open-source the project once I’ve finished preparing it properly. Thanks again for bringing this up!

Also adding that CG does have a portfolio app, but requires sign in to their site i believe and in general their site is riddled with bloat

Can confirm that it worked now. The export button now export a json file.

Speaking of testing, is there any plan to add more accessibility options? For example, font size. I think it's quite simple yet many websites or platforms don't offer that. Personally I find such feature helpful since I don't have to move closer to my screen, or zoom out a webapge and somehow broke the CSS. It makes reading text easier too.

Would you prefer manual tracking like this over connecting wallets and exchanges?

Apart from obvious risks, I prefer not to permit stuff that could leak sensitive information, so manual tracking is the way to go to keep data exposure to a minimum.
^{- BTW, It'd be better if the area chart wasn't just a static image and different entries from the same cryptocurrencies were shown separately on the portfolio page, so we can clearly see the profit/loss for each.}

Not as simple as you might think, when accounting for mobile, but I think I implemented it okay (only testing on Android, on iOS smaller screens it probably doesn't look good).

Makes sense, I added an option to split them apart or not. I was thinking of also making it so you can add multiple portfolios as well and swipe between them.

Not sure about the difficulty, but I'm using mac to view your site and I notices there are a lot of empty spaces around the main content. Maybe you can make it so that the font get larger if the web detects the user has a large screen ratio or something similar. It's more about accessibility so I can understand if it's not the priority right now.

What works for me is manually changing the font size throug dev tools, but I assume most people won't bother with it.

Oh I was thinking large font on mobile, how big is your screen and how blind are you ?  

On Chrome using the zoom (Ctrl+) it seems pretty decently big?

Everything looks great. I did a test using Chrome, and built a portfolio, downloaded the JSON file from the settings, and used Mozilla and Brave to upload the JSON file. My portfolio showed up but when trying to add another coin to my portfolio, there is no search bar to add a coin that isn't listed under Popular Coins. Am I missing something here?

The search is at the top, but I think from a UX perspective I think it makes sense to put the search in the red area instead, I guess it just depends how long your watchlist is maybe

[kryme]

Actually you must mean the Portfolio page, there's no search on that, as my thought was that you'd check the Markets page for coins you want to add and the quick add popular assets was just for convenience, but I think a search bar there makes sense as well.
