App Marketing Review from Oleg Naumov
We were looking for a company that could promote our delivery app. We had a really hard KPI and special target audience so we needed a professional agency for effective ad campaigns.
By the right targeting, messaging and catchy creatives the conversion increased and CAC decreased by 20%. As a result, the volume increased by ~ 700%.
We had a rather hard goal to achieve, and we were surprised how easily the Mobio team handled the task.

App Marketing Review from Sergey Devyatov
We needed a company that could promote our mobile app. Our main goals were to acquire more relevant users for our app and find alternative sources for that instead of classic ones.
Mobio Team did a great campaign as a result of which we found our relevant audience and target with CPA close to KPI.

App Marketing Review from Sergey Alyautdinov
One of the main tasks of promotion was to motivate and encourage users who installed the application, but used it only once or never at all, to place an order.
An advertising campaign with a multi-format showed good results: it was possible not only to achieve KPIs, but also to exceed them. CPO decreased by 51%, CR increased by 15%.
Mobio really does what they promise. They have a lot of experience in our industry, so everything they did was 100% right and well-planned.
