My favorite app is AppLock
Now our mobile phone contains a lot of personal information and privacy, that’s why we need to pay more attention to phone privacy.
AppLock can lock Facebook, Whatsapp, Gallery, Messenger, Snapchat, Instagram, SMS, Contacts, Gmail, Settings, incoming calls and any app you choose. Prevent unauthorized access and guard privacy. Ensure security.
AppLock can hide pictures and videos. Hidden pictures and videos are vanished from Gallery and only visible in the photo and video vault. Protect private memories easily. No pin, no way.
AppLock has random keyboard and invisible pattern lock. No more worry people may peep the pin or pattern. Safer!
I am more a favorite app than a website, because the app is easier to use and practical.
and for favorite tech I like Android mobile.
My favorite app presently is Discord. Discord is pretty much the best instant means of communication with almost any group on Steemit. It's an extremely important part of building your network, increasing you awareness of steemit as a whole and the services built on top of this blockchain and building your reputation through increased following on Steemit.
At the moment, my favorite app is Letgo.
My favorite website is coinmarketcap.com. With the help of this website I can look at the price of cryptocurrencies, how much they rose or falled in price, past snapshots, Besides l can find convenient exchange to buy or sell cryptocurrencies and know the volume of the exchanges.
