Lately in crypto currency i have noticed that 70% of every free wallet isn't that secure and its not worth the risk.
You can simply download imtoken 2.0 and launch out your eos with just 1$ eth or less.
Don't gamble on a free wallet.
It definitely doesn't worth to risk with unknown free wallets. Nothing costs more than something that's free

1$ is a real fair price to be secured and to support developers. But I can fully understand the OP - it's a crypto area and there must be free opensource solutions around.
