Security comes first for me, so I try to be careful when choosing a wallet. I would say Freewallet is perfectly secure for an online wallet. Things like 2FA and limits make me feel more at ease with my coins there. Yes, this still falls short of the level of hardware wallets, but for storing coins for short time, this wallet is excellent. As a disadvantage, I would attribute the inability to get the private key at your disposal. I hope they will add this feature soon.
