Uncovering Hidden Costs When Researching Mobile App Agencies
So you’ve finally decided that you’re ready to build a mobile app. That’s exciting news! Maybe the app is for your e-commerce shop or intended to improve your internal business communications. Who knows? Maybe you have a great idea for an app and want it to become the next Snapchat.
Regardless of your scenario, you need to figure out exactly how you’re going to develop your app. Finding a mobile app development agency is a logical place to start.
There’s just one problem. You’ll likely find hundreds of different agencies to choose from. How can you possibly know which one is the best for your app?
Key Takeaways
- Agency Selection: Narrow down choices based on location, reputation, and cost transparency.
- Platform Coverage: Ensure bids include both iOS and Android to avoid doubling costs later.
- Development Type: Opt for hybrid app development to save on costs.
- Technology Requirements: Confirm all necessary technology is included in the bid to prevent unexpected charges.
- Timeline Impact: Be aware of how development timelines can affect overall costs.
Fortunately, you’ll be able to eliminate some options right away based on things like their location or reputation. But once you start narrowing your choices down, the cost of your app will likely play a major role in your decision-making process.
Unfortunately, not every agency is always transparent about their pricing.
If you don’t know what questions to ask an agency, then you could end up building an app that costs double or triple the amount that you initially thought.
Don’t get me wrong; this is not necessarily because agencies are trying to deceive you. While there are certainly some bad apples out there, this won’t be the case for the most part.
Some important mobile app development factors just might not be included in your initial bid from a developer. So it’s in your best interest to get all of this information clarified from the beginning to avoid unpleasant surprises down the road.
So use this guide to help you get a more accurate bid from the mobile app agencies you’re considering for your app development project.
Here are some of the most common hidden costs you need to ask about:
Pre-Launch Hidden Costs
The simplest way to break down hidden costs is by pre-launch and post-launch. So the first thing we’ll do is cover the questions you need to ask an agency related to the development process.
What Platforms Are Covered?
There are two platforms for mobile app development; iOS and Android. The total cost to develop an app for each platform will vary, with Android development being slightly more expensive than iOS development.
| Platform | Cost Consideration |
|---|---|
| iOS | Generally less expensive than Android |
| Android | Slightly more expensive due to complexity |
| Hybrid | Cost-effective for both platforms simultaneously |
So this question is simple. When you’re consulting with a development agency, just ask if the bid includes iOS, Android, or both. Assuming you’ll want your app exposed to the widest possible audience, you want to find a bid that includes development for both platforms.
If you don’t ask, your final product may only be half of what you expected, and the additional costs could ultimately double to deliver what you need.
You should also inquire about the type of development the agency is going to use when building your app for each platform. If they are planning to build a traditional native app, then they will have to build two separate versions for each platform.
This development process will add unnecessary costs to your bid.
Look for a development agency that can build hybrid apps. In this case, you can build for iOS and Android simultaneously, without having to develop two separate apps.
Finding out if your prospective developer offers hybrid development can save you from a significant amount of hidden costs as well.
What Technology is Required?
According to a recent study, the average cost of a mobile app ranges from $38,000 to $171,000.

Obviously, there is a huge difference from the bottom of this price range to the top. That’s because all apps are not created equally.
As you can see from the graph, a huge portion of that price is related to features and infrastructure. Both of these factors are related to the technology needed to make your app work.
It’s like asking about the average cost of a house. If you want to buy a one-bedroom house with 500 square feet in the middle of nowhere, it will cost significantly less than a six-bedroom, 4,000 square foot house by the ocean.
Apps are the same way. The price will depend on the features you want, and the technology required to meet those needs.
All too often, I see people who want to build an app focus all of their attention on app features. There’s nothing wrong with this, but you need to understand the technology behind those features as well, and how that technology will impact the cost.
For example, if you want to save user information, make sure your bid includes a database server. If you want to conduct user analytics, make sure your bid includes an analytics server.
An app that allows users to log in will need an authentication server and an app that sends push notifications will require a push notification server.
The list goes on and on. Each new feature will require a supporting piece of technology, which ultimately increases the cost.
So ask your development agency if all of the technology is included in the bid. Otherwise, you could be surprised to see some hefty upcharges when everything is complete.
How Long Will it Take to Build?
Depending on the agency, your development timeline could impact your final cost. It all depends on how they set up your bid.
For example, if they’re charging you a fixed monthly rate until the development is finished, your app could end up becoming much more expensive than anticipated if they fall behind schedule.
Here’s a look at some different steps in the development process.

As you can imagine, there is no one-size-fits-all answer to how long it takes to build an app.
We’ve previously published a guide on mobile app development timelines. During our research, we discovered:
- 24% of apps take 1-3 months to build
- 48% of apps take 4-6 months to build
- 16% of apps take 7-9 months to build
- 12% of apps take 10 or more months to build
So for the most part, there’s a good chance that you can build an app in six months or less.
If an app development agency is telling you that this process will take longer, make sure to ask if the bid is related to the time frame. You want to make sure that the price is fixed, regardless of how long it takes to develop.
How Will the App Be Secured?
While it may not be the first thing that comes to mind when you’re thinking about app development, security is certainly one of the most important features to consider.
But again, not every development agency will include this pricing in their bid. So you need to ask if your quote covers all of the necessary firewallsWhen you’re narrowing down your choice of mobile app developers, just make sure you take a close look at your bids to make sure that you won’t be surprised by hidden costs down the road.
| Aspect | Agency A | Agency B |
|---|---|---|
| Initial Cost | Lower | Higher |
| Included Costs | May exclude technology, security, or support | Includes technology, security, and support |
At first glance, you may think that one agency is significantly cheaper than the other. However, upon further inspection, it might be because they didn’t include the costs related to technology, security, or support.
Being able to distinguish between pre-launch and post-launch costs is crucial from a budget standpoint as well.
When you’re shopping around for a developer, just be sure to ask these questions. So use this guide as a reference for figuring out which questions to ask.
