Pro Social Account Integration for learning new languages
Pro Gesture system
The most unique aspect about Fleksy is it's gesture system. The middle row of keys that is grayed out serves as the gesture row. The gesture row uses swipes to input spaces, periods, and correction all while you are typing. Of course this new way of typing will definitely take some to get used to.
Pro Modern design
The Fleksy experience from the opening tutorial to the design of the keyboard is extremely well developed and very modern. Almost all reviews note the appearance as one of it's best features.

Pro Type without looking at the keyboard

The combination of accurate prediction and gestures allow you to focus on the text you are actually typing not the keyboard.
Pro Minimalist design
Pro Smooth Popup keypress
Fleksy has a very smooth keypress.
Pro "Mini" mode
Fleksy is able to offer a "mini" sized keyboard that is shorter in height because the whole row of keys with the spacebar is hidden. Fleksy is able to do this because spaces, periods, and corrections can all be performed with simple gestures. "Mini" mode can be accessed at any time by swiping the keyboard down with two fingers. "Mini" mode saves critical screen real estate.
Pro Holds world record for fastest typing on a touchscreen
Fleksy broke the world record by typing "The razor-toothed piranhas of the genera Serrasalmus and Pygocentrus are the most ferocious freshwater fish in the world. In reality they seldom attack a human."

Cons
Con Swipe recognition not as smart as Swype
It requires much more precision, if you miss one letter you have little chance of having the desired word, which makes it difficult to use in some situations.
Con Privacy, automatically saves unknown words
E.g. passwords entered in plain text fields, place names, people names etc.
Con High data bandwidth usage
This product consumes several MB per week, sometimes per day. The fact that SwiftKey doesn't fix the bug despite many similar reports is not really reassuring.
Con No language separation or weighing
If you load several languages, you can choose any keyboard for any of them, but it won't help the recognition algorithm, which insists on giving other language words in the most absurd situations.
Again, no help from their support to arrange the situation.
Con Cannot remove some options
You cannot remove the emojis or Info button from the keyboard.
Con Themes are in app purchases
Like most third party keyboards, Swiftkey offers tons of themes but of course they cost money and have to be purchased through the app.
Con The smallest layout is too big
Con High processor/memory usage makes it unusable on older devices
SwiftKey is extremely resource-intensive compared to many of its competitors, and will often lag even on high-end smartphones.
Con Predicting and inserting word combinations faulty
Recent update enabled Swiftkey to predict short word combinations. In principle this should be quite convenient, but so far it turns out this new algorithm is defective and way too aggressive. Too often it inserts combinations that are completely meaningless, or inserts English combinations in Dutch sentences or the other way around. Has almost doubled the amount of corrections needed.
Con Bought by Microsoft
Will undoubtedly lead to less innovation.
Con No swipe input
Fleksy does not use the popular swype function for typing.
Con Requires swiping to change the language
Requires swiping to change the language, making it difficult for users who mix multiple languages in their conversations.
Con Can't deactivate keyboard addons/apps
Con Only 4 Extension Slot for Free Users
Con 42 Languanges Only
Con Cloud Backup Not Supported
