Return ad is enabled by default upon SDK integration. In order to disable it, please follow the instructions in the integration user guide.


Interstitial Ad

The Start.io interstitial is a full-screen ad unit, usually served at natural transition points during the app lifecycle. When an app shows an interstitial ad, the user has the choice to either tap on the ad and continue to its destination or close it and return to the app. We support static, video and rewarded video interstitials. 

Static Interstitial 

Interstitial is a full-page ad displayed before or after a certain content page or action, such as upon entering a stage, between stages, while waiting for an action, or upon exiting the application.



Interstitial Video ads are effective in keeping players engaged. They convey more information in a short period of time through motion, sight, and sound.

Rewarded Video

Start.io Rewarded video ads are interstitial video ads that provide a reward to the user in exchange for watching an entire video ad.


Banner Ad

App banner ads occupy a spot within an app's layout, either at the top or bottom of the device screen. They stay on screen while users are interacting with the app, and can refresh automatically after a certain period of time.

Standard Banner (320X50/300X50)


Medium rectangle (MREC) Banner (300x250)

MREC is one of the most widely available ad sizes on mobile devices. For this reason, the 300×250 MREC in app banner ad tends to be popular with advertisers, which leads to increased publisher earnings.


Cover Banner (1200x628/7)

Cover banner is a 1200×628/7 ad that is commonly used in social media feeds as well as for native user experiences.


Native Ad

Start.io native ad format embraces, rather than rejects, the user’s desire to remain uninterrupted during the app experience. Native ads have no predefined UI, which gives you the freedom to design and control the ad exactly as you want. Using Native ads, you can design an ad experience that perfectly fits your application’s style, content and functionality.
