GetSocial is a software as a service solution for mobile apps empowering marketing and product teams with growth tools to maximize user acquisition, engagement, and retention.
I've been using Getsocial since June 2016 for my games (Fancy Cats and Fancy Dogs). So far so good, I've been really satisfied with the tool. The support is also very friendly and effective (hey Viral). The pricing, IMO, could be a bit "better", for example: users from different country tiers will have different "value", for a certain month I may have store featuring with hundred thousands of new users but mostly from 3rd tier countries, so perhaps you should consider "ratios" (e.g. 0.6 for users in 2nd-tier countries, 0.3 for users in 3rs-tier countries).
Pros:Excellent service to engage, retain, and grow your game
Cons:Pricing
Totally worth integrating into your games
Pros:Extremely easy to integrate, and an essential social platform every game deserves. developer support is stellar!
Cons:Not a fan of the UI integration
I just love those guys. With GetSocial our app got 10x more shares and users that came thought GetSocial retained much longer
Pros:Easy to integrate, drives organic UA, great support
Cons:No swift examples in docs
