Glad to welcome all users and guests to the forum, as we have developed a new product I would like to hear your feedback on it. I will be grateful for every criticism of the product. Thank you. Initially my team and I wanted to make such an app for ourselves, but we thought it would be good to share it with people. 
Site: rexbag.net
App in google play: RexBag - Crypto Portfolio

PORTFOLIO
PORTFOLIO CONTAINS EXCHANGES, COLD WALLETS AND NOTES
You can create multiple portfolios and connect exchanges, cold wallets and write notes to them. Data within the portfolio, such as the amount of coins and their current value, is synchronized and calculated automatically.
SUPPORT FOR 50+ EXCHANGES AND 500+ COLD WALLETS
Support for coins Bitcoin, Ethereum, BNB, Ripple, Cardano, Doge, Matic and 500+.
Support for exchanges Binance, Coinbase, Kraken, Kucoin, Bitfinex, Bittrex, Gate and 25+.
SECURELY CONNECT PORTFOLIO DATA
We maintain security standards and store and transmit encrypted data. Required read-only keys when connecting exchanges, and when connecting a cold wallet, you only need its wallet address.
NOTES
The ability to record in any convenient form, gives you the freedom to keep track of your assets. Add both regular transactions(linked to the connected assets), and anonymous transactions(not linked to anything and don't know about assets). All types of transaction will be calculated automatically and divided into members with their own balances and transactions within each portfolio.
STABLE RATE USING VARIOUS SOURCES
We maintain rate stability independently - our rates are averaged between many exchanges. And if there is no rate on a particular exchange, we will use RexBag Clear Price.
COINS
Track coin prices and their history. Analyze information about coins and predict their exchange rates.
REAL TIME COINS RATE LIST
Watch the fair rate and changes in 24 hours for over 500+ coins. Sort them by change in 24 hours and by price in both ascending and descending order. A flexible search by short and full coin name is also available.
LIVE AND HISTORY CHARTS
Live chart shows the current price every second. Detailed history chart of the coin's price in different time periods as well as information about the coin like its capitalization, 24 hour turnover, cheapest and the most expensive will help you analyze coin.
COIN RATES AT VARIOUS EXCHANGES
View coin rates at various exchanges, analyze the price, buy and sell profitably. You no longer need to go to every exchange and manually compare rates, now everything is in one place.
PRICE ALERTS
Follow coin price changes. By taking advantage of the rule on significant changes in the price of a coin, you will be aware of important changes in the cryptocurrency market. And using the rule of reaching a certain price or changing by a certain value or percent, you can delegate the threshold tracking to RexBag app.
APP PUSH OR TELEGRAM BOT
Receive notifications about changes in the price of coins either by a app push or by a message in a telegram from the RexBag Alert Bot.
CHANGES IN VALUE OR PERCENT
The flexible settings allow you to track changes in specific values and changes in percentages relative to initial price. Thus, you will not miss an opportunity to buy or sell assets at a profit.
GENERAL RATE OR ON SPECIFIC EXCHANGES
You will also be able to create alert notifications not only for the general RexBag Clear Price, but also for rate of specific exchange. In this way, you will be able to track not only a coin's rate, but also assess whether an exchange is profitable for you in the long run.
