Wallet Tracker by Smart DeX Solutions is a free Android app that allows you to track, manage, and add multiple cryptocurrency wallets with real-time information. It supports more than 50 popular assets, including Bitcoin, Ethereum, BNB, Cardano, Solana, Dogecoin, and Matic. The app never asks for any sensitive information related to your accounts, such as username, password, keystore, JSON file, or mnemonic phrase. Instead, it stores only the public address you provide for every wallet in a private database, which is inaccessible to anyone other than you.

One of the main features of Wallet Tracker is its ability to add as many wallets as you want and show the current balance available in each wallet, along with its conversion to EUR/USD/GBP/etc. in real-time. The app also displays the overall balance in EUR/USD/GBP/etc. Additionally, all wallets are identified by an alias that you can edit at any time. Real-time market data and exchange charts are also available for each coin.

In terms of security, Wallet Tracker offers the option to set a security pin or unlock the app using biometrics. The app never stores any sensitive information, making it a safe and reliable tool for managing your cryptocurrency wallets on the go.
