Woot excited to see you using our API! Hope you like it and happy to hear any feedbacks you may have  Cheesy

You API is simply the best on the market, it is one of the few API's that don't require a key, which is what I needed, since I don't have backend, and on top of that it has so many features. At the beginning I've tried to keep my app API-agnostic to always have fallbacks, but other API's lack your features and I'm considering discontinuing using them.

Coin Watcher is a free, open source and privacy-oriented cryptocurrency portfolio tracking web app. It stores all user data strictly on client side utilizing window.localStorage, while market data is fetched from public API's. The app was built using Progressive Web Application technologies (PWA), so it is available even offline and can be installed on mobile and desktop from the browser (via add to Home Screen). Users who don't want to trust a website can built the app locally and run it as local html file. Currently the app is very simple, it doesn't have a chart or ROI, but this may be added in the future if there will be demand.

This app uses cryptocurrency market data provided by the following public API's:

CoinGecko

Alternative

Coinmarketcap

Woot excited to see you using our API! Hope you like it and happy to hear any feedbacks you may have  Cheesy

I tried the portfolio web app, and I add LTC and SC as an example. I see that it is interesting to see the portfolio without login in the exchanges because we can see how much profit and loss we already made. I wonder how to create an apk for the android because I am sure it will help people to check their portfolio. I hope that someone can do that and release it in the PlayStore.

I think the default color will be good in the black because it does not make dazzle or annoying. Oh, by the way, the price will auto-refresh for itself, right?

It shouldn't be hard to convert it into native app for both desktop and mobile, but for now you can add it to Home Screen if you visit it with a Chrome browser and it will loop and feel similarly to an app.

Yes, the prices are automatically updated, you can choose the interval in settings, it can be 2 min, 5 min, 15 min.

Yes, I think the same as you but perhaps, I will ask with some of my friends who familiar with the app for mobile, and I hope that they can try to make it for the mobile app and I think it could be better for the user itself.

I guess for the desktop installation, the user can follow your instruction to install in their folder so they can load the index.html in their browser.

Yes, I try with 2 min, and it works perfectly without any problem.

Gladly im able to find that custom color but i do seek out on how to change that Cyan Background. It do really hurts my eyes  Cool Overall the software is good.

Not possible yet, will add soon! I've spent most of my time developing it in smallscreen mode, so I rarely see that Cyan bg, didn't realize it's annoying. What color do you think should be default?

Cant make it the same with other settings which you can able to customize?

Btw, i tried to put up some shitty coins of mine like KCY(KickCity). Among on the API being used trying out to search which exchange its being traded but i cant find.  Cry

Edit: Oh, i found it on coingecko.

The official page is good but for me it loads a bit slow, like the loading signal shows for 15 seconds long before stopping? On the good side,,, I also tried adding 1 coin I have, and the value was quite accurate so the API is working very well.


When you launch the app for the first time, it loads the list of all available coins from all crypto api's, so it can then resolve coin names to make requests. The response is saved and is updated (in non-blocking way) every few days, so it only should be slow for the first time you visit the site. Try to open the app again, it should be fast now. Also, in the latest update I've given max time of 6 seconds for this initial loading (if it takes longer, it skips it) for alternative.me API, since it is accessed via proxy, which is the reason why it was slow.


Is there a way to keep history for a time period, like if I enter the date I bought it, I want to see PL for the coin I have in my value. Thank you.

At the moment no, but if I'll keep extending this project, making portfolio transactional and adding charts/ROI would be on my top priority.

The software is good, prices are superbly updated but there are some drawbacks:

 - Edit crypto: When I edit/update a currency, I can only edit it after deleting it or clicking on the "Home" button.
 - Direct button to remove: The cryptos should be removed by clicking on the icon on the same page.
 - select market data: CoinGecko or Coinmarketcap

Hi, and thank you for your feedback!

1) This is by design, edit action is based on element's "change" event, so it fires when input loses focus, meaning you can just click/tap anywhere outside of input form. I've also added a listener on "Enter" key press, but it hasn't been consistent on mobile, I'll investigate it further. Fixed now.

I specifically didn't want to add "confirm" button because they should be avoided whenever possible.

2) Removing coins usually doesn't happen too often, so additional buttons would only clutter the main page. Most of the apps that I've checked don't do this.

3) Currently the app tries to get data from CoinGecko, if it fails it tries to get from Alternativeme, then if it fails it tries Coinmarketcap (and if some of the requests takes too long, it switches to race mode when it gets the data from the fastest API). I was going to add an option for picking the order of API's, but it's not very straightforward to implement and is probably not very useful. I'll probably add it as a console command for advanced users.
Also, coinmarketcap will eventually get removed, because they are discontinuing their public API.
