Custom mobile apps


On-demand taxi apps usually consist of two separate in-app roles or apps: Driver’s and Passenger’s. Beside basic functionality, taxi apps require map APIs (Google Maps, MapKit), payment gateways (Stripe, PayPal) and in-app calling feature integration (Twilio, Bandwith).


When creating media streaming apps, we take care of seamless content delivery and work with trustful media processing platforms (Livestream, Brightcove). Streaming apps also require data storage (Cassandra, MySQL), geolocation (Google Maps, MapKit), etc.


Payments and money transfers were among the first to be distrupted by technological advancement. Otimbi Labs has an extensive experience in working with banks and FinTech companies in order to build payment and mobile wallet apps.


Delivery applications usually consist of two separate apps: for customers and for couriers. Must-have features for delivery apps are geolocation (Google Maps, MapKit), email messaging (SendGrid), payments (Braintree, Stripe), analytics (Mixpanel), and others.


Marketplace apps usually act as intermediaries between two parties: buyer and seller of goods or services. These solutions should be lightning fast and have a robust analytics powered with machine learning (Amazon ML).
