Monerujo is a Monero multi-wallet that operates with great receptivity and provides a fun view and design. If I liked it is because of that. Sincerely, the design is simple but updated, and they offer the benefits of a practical approach. Although this wallet is a release specially designed for Monero, there exist good rates for storing and trading other Altcoins including the leader Bitcoin. Moreover, the process for entering the wallet is easy and effective.
The security of this wallet is ensured by the open-source program it offers. There is no risk of safety alterations and other bugs. In general, it is completed with a good distribution of functions. It is also easy to use in mobiles. I think it is one of the easiest wallets I've ever seen. But it is also one of the shortest releases from Monero. From a trader side, I think it is limited and not very fictional. In today's world, we use a wallet that even permits to trade not only BTC but other altcoins.
The company has done a good effort to correct the issues related to the customer's support. It is now more operative and with active community sections, but they seem to reject to integrate other altcoins as part of the trading and payments with the Monero token.
In conclusion, Monerujo is little in the market. It became one of the less talked wallets, and it is not in the top of most reliable products for storing Monero anymore. Anyway, there are guaranteed factors to use it, but I do not recommend it at all.
