Roy Glasberg, Global Lead, Launchpad and Launchpad Accelerator
Last month, the second cohort of Launchpad Accelerator, Google’s high-touch global program for late-stage startups, came and conquered their app challenges with the help of mentors at Google HQ.
What did they learn that they’d like to share with developers across the world? Check out the video below for solutions from 3 different startups, and an in-depth review of MagicPin’s mobile web challenge and solution.
Startup:
MagicPin from India is a social network app that curates a local user base around locations, allowing merchants to connect with these specific audiences.
Mobile web challenge:
In India, downloading an app requires a high commitment. On average a user would keep 5 or 6 apps on their phone. According to Anshoo Sharma, Co-Founder and CEO, MagicPin, “If you want to be the next app that they download, there is a high barrier.”
Jordan Adler, Google Developer Advocate: “Devices in markets like India have limited space--on average 128 MB of memory--and when you add in system features only 40 bytes of user space is left. And if a typical APK is a few megabytes, you can only have a few apps before you have to stop downloading.”
Solution:
Jordan Adler: “One of the great things about Progressive Web Apps is you don’t have to request the commitment (to download an app) upfront. You can start to build a relationship with the user through the web interface, and over time the web app can become more like a native app, it can be housed on a device, cache content and work offline.”
Anshoo Sharma: “In the last 1.5 weeks we have been here we have already launched a micro version of our platform on Progressive Web Apps. And the experience is great! Without using the (mobile) app people can get as good an experience.”
About Launchpad Accelerator
Launchpad Accelerator is a six-month accelerator that enables late-stage app startups from emerging markets to successfully scale. Here's a two-minute video about the Accelerator.

‘TOP-UP WARNING.’ ‘NO CONNECTION.’ ‘INSUFFICIENT BANDWIDTH TO PLAY THIS RESOURCE.’
These are common warnings for many smartphone users around the world.
To build products that work for billions of users, developers must address key challenges: limited or intermittent connectivity, device compatibility, varying screen sizes, high data costs, short-lived batteries. We first presented developers.google.com/billions and related Android and Web resources at Google I/O last month, and today you can watch the video presentations about Android or the Web.
These best practices can help developers reach billions by delivering exceptional performance across a range of connections, data plans, and devices. g.co/dev/billions will help you:
Seamlessly transition between slow, intermediate, and offline environments
Your users move from place to place, from speedy wireless to patchy or expensive data. Manage these transitions by storing data, queueing requests, optimizing image handling, and performing core functions entirely offline.
Provide the right content for the right context
Keep context in mind - how and where do your users consume your content? Selecting text and media that works well across different viewport sizes, keeping text short (for scrolling on the go), providing a simple UI that doesn’t distract from content, and removing redundant content can all increase perception of your app’s quality while giving real performance gains like reduced data transfer. Once these practices are in place, localization options can grow audience reach and increase engagement.
Optimize for mobile hardware
Ensure your app or Web content is served and runs well for your widest possible addressable market, covering all actively used OS versions, while still following best practices, by testing on virtual or actual devices in target markets. Native Android apps should set minimum and target SDKs. Also, remember low cost phones have smaller amounts of RAM; apps should therefore adjust usage accordingly and minimize background running. For in-depth information on minimizing APK size, check out this series of Medium posts. On the Web, optimize JavaScript CPU usage, avoid raster image rendering, and minimize resource requests.

Reduce battery consumption
Low cost phones usually have shorter battery life. Users are sensitive to battery consumption levels and excessive consumption can lead to a high uninstall rate or avoidance of your site. Benchmark your battery usage against sessions on other pages or apps, or using tools such as Battery Historian, and avoid long-running processes which drain batteries.
Conserve data usage
Whatever you’re building, conserve data usage in three simple steps: understand loading requirements, reduce the amount of data required for interaction, and streamline navigation so users get what they want quickly. Conserving data on behalf of your users (and with native apps, offering configurable network usage) helps retain data-sensitive users -- especially those on prepaid plans or contracts with limited data -- as even “unlimited” plans can become expensive when roaming or if unexpected fees are applied.
