Building a messaging app means solving real-time delivery, contact sync and store approval — the three problems that sink most first-time app projects.

Xter Texter went through the full cycle with us: user experience design, application development, and the backend that keeps messages moving reliably.

What the client said

★★★★★

I discovered LA NPDT when I was looking for a firm to develop a mobile app. I was really impressed with the way they listened and the way they made sure they understood what I was trying to communicate.

There are many steps if you continue to pursue any project, but along the way LA NPDT has helped and guided me when they were not expected or required to. If you have been holding back on your dream project, get off the couch and go get your dreams! I highly recommend a consultation with LA NPDT to get a great perspective on your project.

The client

Jesse Mungia found a need for a mobile app one morning when he didn’t want to text his wife while she was driving, but he didn’t want to forget to message her.
Mr. Mungia wanted to make an app that simply didn’t present the opportunity for distraction, rather it held message notifications until someone was actively using their phone.
That’s when the idea for XTER TEXTER was created and Mr. Mungia chose LA NPDT to develop his mobile app.

The challenge

Geofencing quiet zone settings in XTER TEXTER
The app had to hold an incoming message until the recipient was already using their phone, then release it. On iOS that fights the platform: apps cannot watch what other apps are doing, so the usual "detect activity" approach is simply unavailable.
We worked within the sandbox instead of around it, using the signals iOS does expose to infer that the phone is in active use before a held message is surfaced.
This means that if someone is busy driving, attending class, or giving a presentation, they can trust XTER TEXTER to keep their messages for when they are available later. XTER TEXTER takes advantage of one’s tendency to check their phone immediately when they receive a text by simply delaying that notification.
Not only did Mr. Mungia need the software development services, but our marketing services as well. He needed us to come up with a strategy to market or license his app, and to evaluate what were the best possible routes for a successful app

Our solution

The Android build could monitor activity directly, so the delay logic was written once with a platform-specific trigger layer underneath — same behaviour for the user, different mechanics on each OS.
LA NPDT implemented extra features in XTER TEXTER to bolster the distraction prevention element; extra features such as scheduled Do Not Disturb mode and geofencing quiet zones.
These additional features in XTER TEXTER benefits users so that messaging through the mobile app is a worry-free experience on any platform.
We developed a landing page for XTER TEXTER that explains the main vision of the app as well as its features. This landing page was used for the app store descriptions for both iOS and Android versions.

The result

Mr. Mungia saw the need for a mobile app that allowed for safe, undistracted texting.
He relied on LA NPDT to realize his vision and develop a mobile app that aligned with his idea. LA NPDT’s software development capabilities resulted in a fully functional app, along with the many other benefits of working with an all-inclusive product development team.
Alongside LA NPDT, Mr. Mungia has been able to strategize the marketing of his app for release, which involves seeking corporate partners and sponsors.

Off-the-shelf stops working at the edges

Companies commission custom software when their process no longer fits a subscription tool — a compliance rule, an odd data model, a workflow that three departments share. The risk is building an expensive replica of the tool they already rejected. We spend the first phase writing down the specific behaviors that off-the-shelf cannot do, and design around those.

How we delivered Xter Texter

We turned the client's process into a written specification, designed screens around the tasks people repeat dozens of times a day, and built in increments the client could use early. Testing covered messaging edge cases — failures, retries, opt-outs — before launch, and the handoff included documentation so an internal admin could run it.

Frequently asked questions

How do you scope custom software?

A short discovery phase produces a specification and estimate. You can take that document elsewhere if you choose — it is yours.

Will we be dependent on you for maintenance?

No. Code, infrastructure and documentation are delivered to you; we offer support but you are not locked in.

Can you integrate with our existing systems?

Yes — CRMs, ERPs, payment processors and internal databases through their APIs or direct connections.

What messaging app development actually involves

  1. 1. Design the conversation flow first

    A messaging app lives or dies on how fast a user goes from opening the app to sending a message. That flow gets designed and tested before any other screen.

  2. 2. Build delivery to be reliable, not just fast

    Messages must arrive on bad connections, after app restarts and across devices. The backend architecture for queuing and retry is where messaging apps are won or lost.

  3. 3. Handle contacts and privacy deliberately

    Contact sync triggers permission prompts and store privacy review. How the app asks, and what it does with the data, has to be designed and disclosed correctly.

  4. 4. Plan for store review from day one

    Messaging features get extra scrutiny in app review. Metadata, permission justifications and demo accounts are prepared before submission, not after a rejection.

Talk to an engineer
How much does it cost to build a messaging app?

A focused messaging app typically runs $50,000 to $150,000 for the first release, with real-time backend infrastructure being the main cost driver.

How long does messaging app development take?

Four to eight months for a first release including backend, plus store review time.

Should I launch on iOS or Android first?

Wherever your audience is — for consumer apps in the US that usually means iOS first or both together via a cross-platform build.
