The most convenient presentation app, according to US Air Force
Presentain’s iOS and Android apps helps presenters and their audiences connect on a whole new level. The application lets a presenter broadcast slides and get audience feedback in real-time. It also allows audience members to send questions to the presenter, effortlessly connect with presenter’s social media accounts, and even record the presentation.
Real-time presentation broadcasting
Presenters can broadcast the slides on a projection screen and straight to audience members’ smart devices.
Lets you record the presenting session to get a slidecast with voiceover.
A presenter can control presentation access, recorded slidecast, and slide sharing.
Polls & stats
By creating and conducting polls and surveys, a presenter can engage the audience with post-insights. Stats show which answer has been chosen most and which poll is the most popular.
Questions from the audience
Presentain allows audience members to send questions during the presentation, and a presenter can show them on the screen while answering.
When the audience connects, Presentain offers to join the presentation via social networks. A presenter gets the audience list with contacts. Also, every recorded session contains its own stats.
Presentain is a long-term project we have been working on for 2 years.
The project activity included:
We’ve extended the mobile functional - ‘Upload a presentation’ and ‘Create poll’ options were added, as well as new features: integration with cloud services, embed code feature for web to generate HTML that can be embedded in a site or blog.
On a new Presentain logo, we wanted to translate its functional versatility.
There were several challenges on the tech side. Many Presentain users connect to the presentation via one WI-Fi spot. When the internet channel gets overloaded, the connection crashes and Presentain stops working. Also, we needed to minimize a delay between the action on the presenter’s device and broadcasting on the screens.
During the development process, we received a request from one of the most valued Presentain customers - US Air Force - to increase the number of connected audiences by 4 times for their great upcoming presentation.
As for the iOS version, we have simplified the code by getting rid of global variables. Now, the information transfers between the activities by events.
