Segwit or Segregated Witness, is a SoftFork of Bitcoin and was formulated by Bitcoin Developer Peter Wuille. It was initiated on 24th of August, 2017.
Bitcoin network is suffering as more and more transactions are made causing delays, and due to a huge backlog in processing, it takes hours to confirm a transaction. To solve this, SegWit was implemented.
The implementation of Segwit proposed as a means of scaling bitcoin to meet increased demand and expected to decrease congestion in the Bitcoin network which means faster transactions and much lower fees.
Within 1 year and over 5 months after implementing Segregated Witness to the network there are a lot of Segwit compatible wallets in Windows, MacOS, and Linux platform had been developed. Due to the high demand of smartphone users; more people use this platform as the ease of use. Why send bitcoins using desktop wallets where you have to open a laptop or PC where you just have to send only a couple of dollars worth in bitcoins while you can just pick your smartphone on your pocket and open the wallet app then ready for sending within just seconds.

Notice: Due to security vulnerability of coinomi wallet this February, even though they announced that their mobile wallet isn't affected of this vulnerability and due to it's closed source so for all you know they might do a lot of shady things without you knowing it. I may suggest that use this wallet for your own risk .
This list are wallets where you can fully control your funds, where these wallets may or never relies on a centralized service or a third party. So its users are fully responsible for the security of their device to protect their funds from malicious attempts of any kind of malware.
As time goes, I'm hoping that more wallet and even more exchanges will support SegWit to avoid a congested network and lower fees in the future.
Please always make sure you have backups of your master seed and private keys! Don't ever share that to anyone.
Remember, Not your keys, not your Bitcoins.
