MassSender: from idea to a growing iOS app.
MassSender is a bulk-messaging iOS app that PRP Webs designed, built and continues to grow. We did not just ship it and walk away — we keep improving it release after release, making it more useful and lifting its revenue over time.
The challenge
Sending messages in bulk is usually clunky and technical. MassSender needed to make it simple enough for anyone to use on their phone — and it needed to keep earning, which means the work never really ends at launch.
What we did
Designed the app
We designed MassSender from the ground up — a clean, simple interface that lets anyone send bulk messages across channels without a learning curve.
Built it for iOS
We developed the full iOS app and shipped it to the App Store — stable, fast and built to handle real messaging volume.
Kept improving it
We did not stop at launch. We ship regular updates — new features, fixes and refinements based on how real users behave.
Grew the revenue
Each release is aimed at making the app more useful and more successful, steadily lifting its revenue over time.
The result
MassSender is live on the App Store and improving with every release. It shows how PRP Webs builds a product — not a one-off launch, but a living app we keep refining to grow its users and its revenue.
Frequently asked questions
What is MassSender?
MassSender is a bulk-messaging iOS app that lets users send messages across channels from one simple interface. PRP Webs designed it, built it for iOS, and continues to improve it release after release.
Does PRP Webs build mobile apps as well as Shopify stores?
Yes. Alongside Shopify development, PRP Webs designs and builds native and cross-platform mobile apps — for our own products like MassSender and for clients, including white-label apps delivered under an agency’s brand.
Do you keep improving apps after launch?
Yes. Launch is the start, not the finish. We run an ongoing cycle of updates — new features, fixes and improvements — measured against real usage and revenue, so the app keeps getting better and earning more.
