To make sure you have made pact with a right solution provider, you must know what questions to ask developers before taking a final plunge. Based on answers, you can develop transparent understanding of their expertise, specialization, professionalism and capabilities. To make it worthwhile, here are the most critical questions you should be asking before hiring an app developer:

1) Can I check a few finest examples of mobile apps you have built?

This is the most fundamental question that must strike your mind before you finalize a deal with a mobile app development company. You can solicit a set of mobile apps that might be exhibited on their online website as case studies. The portfolio is an undeniable testament to substantial experience in the respective domain.

If the company has done something in the past, they will be gladly share a few finest examples of the kind of app they have built earlier. Studying them will help you determine ROI you may get out of the deal.

In case, the prospective agency hesitates or does not have testimonials to show, you can quit going further. If they do have impressive achievements to flaunt along with positive ratings and reviews from other clients or in the App store, you have got something to rely on.

2) Do you understand our business model?

Another vital consideration before hiring mobile app developers is asking if they have some insight into what your business revolves around. The company you have approached should be aware of your business model and its target audience in order to build the app with a design and features that actually appeal to users.

Failing to create an app that does not align with your business strategy and customer requirements will not be a good omen. This is why you should emphasize hiring developers who have worked for clients in relevant niche.

Relevant experience means they understand the type of business and have complete grip on what your customers seek. Talk to the agency about your customers, vision and expected results in order to build strong architecture of UX.

3) Can you list a few clients who share the same business industry as mine?

Appfutura, Clutch, Good firms are a few great business listing portals where top companies are listed for their capabilities, success and power to transform their clients’ businesses. You can alternatively ask the agency to share some clients they have worked with so that you can tell if they can do it for you, too.

The answer to this important question will lead you to gaining an honest look into the actual performance of the agency for similar apps. Apart from that, as you talk to their past clients, you will be able to get the realistic feedback on agency’s development methods, deadlines and pressure management and communication power.

4) What is your team strength and overall capability?

The app development process is dynamic and contains a lot many components. For instance, when prototype changes, the key features also need to changed or improved. This requires a flexible development system with dedicated professionals ready for the massive commitment. The company must provide dedicated manpower who are extensively available to implement changes in their everyday strategy.

To evaluate their team strength and capability, you must investigate what all ongoing projects they have and whether there will be a couple of developers reserved exclusively for your job. A vague response to this approach might influence your decision to hire them for the project.

5) How do you usually approach App Development Process?

Speak a realistic language with an intent to seek a reliable promise from the agency while you ask them to tell you about their development methods and how they operate in critical situations. You must learn the time they take for similar mobile apps and the way they tackle suddenly arrived problems during the phase.

Agile methodology is much preferred nowadays. The knowledge about these things will keep you alert and informed about company’s practical responses in the face of sudden challenges. Always demand agile process of development as it enhances project completion efficiency and ensures speedy delivery of MVP.

6) Tell me about the skill level of your app developers

The agency’s developers should be skilled enough to deliver features and functionality within the app. To build a powerful, smooth structure of app’s backend, developers should be keen on telling you how they would approach it. They would tell you what frameworks and tools are needed to sculpt it to perfection. Ask them to mention similar apps with same features and functionality.

When it comes testing skills of app developers, look for:

  • Personal bio with professional details of work history, education and hobbies
  • Resume
  • Contact information of developers
  • Portfolio highlights with past projects
  • Social media profiles
  • Project-specific skillset
  • Awards and accolades
  • Github links of documentation

7) What all technology services you offer? Are you versatile or have proven specialization?

To avoid controversy later, it is imperative to know if the agency offers entire package of services including Beta testing, Quality Assurance and even launch.

Getting a complete array of services in one pact would lead to confident, hassle-free fruition of the project. Inquire for the following services offered by the agency:

  • Conceptualization
  • UI/UX design creation
  • App Development
  • ROI analysis
  • QA testing
  • Launch and App store optimization
  • Post-launch marketing and maintenance

You need a solid, robust confirmation on this question failing which you might get ripped off. To make sure your mobile app is in the right hands, the agency should:

  • Provide flexible conditions with no rigid outline of limiting the project to fixed resolutions
  • Be open to fluid and agile development process
  • Possess versatile knowledge about technologies and specializations
  • Be clear about upfront charges and hidden fees
  • Offer sustainable time frame

8) What design practices and approach you have for app development?

Ask the agency about their precise approach and practices they adopt for delivering memorable user experience along with stunning features. Without a splendid interface design quality and UX, your app will fail to connect with users. When the apps are designed for popular native platforms like iOS and Android, the design must be unique and superior. App stores also recognize mobile apps with outstanding UX elements and aesthetic appeal. A good mobile app development company will never compromise on design factor.

9) What services you offer after the app launch?

App store optimization is the blazing need of the moment for a finished app to be apparently visible in an app store. To get success in making the app discoverable for users, you need to follow a tedious, grueling path. A good agency knows and often offers the ways of app submission to get it featured in the marketplace.

App release strategy also forms a good part of app marketing. Hire an agency that has mastered launching the app successfully for previous clients and gets actively involved in constant monitoring of app’s performance and user engagement after publishing it. Placing the app in the marketplace is still a job half done. Your app still requires a watch periodically for

  • Regular maintenance
  • Bug detection and fixes
  • Monetization
  • Fresh updates with new features and content

Constant maintenance and updates make sure your app remains on top of user preferences and keeps engaging them for a long time. Ask your agency for clear hourly rates or fixed fees for regular support and maintenance.


The sensible investment of time, efforts and resources is a critical driver of flawless mobile app development process. The questions described above are key to making a right and clever decision for choosing a prospective app development agency you will never regret later. Of course, in addition to cost and time, there is a lot more to consider when it comes judging the talent and capabilities of mobile app developers.

Always emphasize on getting familiar with their technical know how, communication skills, work history, professional attitude, development methods and accountability towards the project. Also check for code ownership rights after the app is developed. Asking these details puts you in a safe spot.

Samsung Galaxy Fold: Everything You Need To Know

The year 2019 is just warming up for new smartphones models and mobile technologies hitting the tech market. Samsung has just made an explosive breakthrough this year as it unveiled its highly anticipated Galaxy Fold at Unpacked 2019 in San Francisco along with its Galaxy S10 devices. The sensational Samsung Galaxy Fold is the first foldable smartphone which made news last year has showed up at the event with more details and deeper look.

Apparently packed with incredible features, the phone is described as Quite good by DJ Koh, Samsung CEO, who also confirmed that it comes with a little higher price tag. Unprecedented and carving its unique category in smartphone devices, Galaxy Fold is prepared to take the world of mobile users by surprise and give tough competition to its rivals. It is quite in buzz due to its original design, display, foldable screen, software and other offerings.

Let’s check out in details all that the phone offers. Here is everything you need to know about phenomenal Samsung Galaxy Fold:

1) Tablet-like structure:

Samsung Galaxy takes to tablet when unfolded from the center and gives you a look and feel of a smartphone structure when folded again at the central spine, which adds to a surreal experience for users. From its sides, it reflects signature Samsung design when opened, and as you fold it back, its size doubles in thickness compared to regular smartphone.

This fold-unfold mechanism – which is located at the hinge of the back – affects the normal size like it is a foldable tablet and not a phone. The unique arrangement, according to Samsung, is something that can survive repeated open-close operations.

2) Range of colors for screen and spine:

Samsung has decided to give you a range of adorable colors to play with the style. Users will be able to customize the phone design and choose a different spine color for more personalized experience.

Made with interlocked gears, the hinge at the back allows users to open and close the device and makes the process unbelievably smooth and easy. Users can customize hinge colors and will be able to enjoy the device in four different colors.

3) Galaxy Fold display:

Galaxy Fold has a Dynamic 7.3 inch AMOLED internal display known as Infinity Flex. Its aspect ratio comes as 4.2:3. As it is fitted on the inside of the device, when folded up, the displays remain unusable.

It has an AMOLED exterior display that works as a second screen measuring 4.6 inches in a diagonal fashion. This makes it stand out among other Samsung phones and does not conform to modern standards as it is tiny. The display screen reposes on the device’s center in contrast with surrounding bezel, which creates unique feel.

As Samsung says, the internal 7.3-inch display comes with a WXGA+ resolution though it is hard to define the exact pixels.

Galaxy Fold Hardware

  • 7nm 64-bit Octa-core Qualcomm Snapdragon processor
  • 12GB RAM
  • 512GB UFS 3.0 storage capacity
  • No Micro SD support
  • 4380mAh battery

Samsung reveals that the device operation is powered by a high-speed 7nm Octa-core Qualcomm Snapdragon 855 processor with gigantic memory storage support of 12GB RAM and 512GB ROM. The huge storage justifies the huge price here. It does not have microSD, which is almost anomalous if we consider other Samsung devices offering SD card convenience.

Galaxy Fold also has 4380mAh battery provision, bigger than other Samsung devices of this caliber, but not that big for modern device battery capacity. The battery is split for both sides of device, each half fitting either side of the device. It contains both wired and wireless fast charging support.

Galaxy Fold software

Galaxy Fold supports multitasking and allows users to work on three apps simultaneously when opened on the larger screen. So you can explore Google Maps, messenger, and a browser simultaneously.

The device is quite adaptive to the software format you are using. If you have opened a browser on its smartphone display, upon unfolding the device you will see it will automatically transfer the browser app to the larger display for better viewing.

Samsung Galaxy Fold cameras

Samsung has perhaps worked miraculously on enhancing camera details in Samsung Galaxy Fold. Users can get the best experience from as many as six total cameras loaded with more modes of use.

  • External Front camera: 10MP, f/2.2
  • External Rear cameras: 16MP ultra wide, f/2.2; 12MP main, f/1.5 & f/2.4; 12MP 2x zoom
  • Front dual cameras (internal): 10MP Camera, f/2.2; 8MP RGB depth, f/1.9

Lying on the outside of the device is the incredible triple-camera arrangement which is comparable with what new Samsung Galaxy S10 has done. Samsung Galaxy Fold allows users to enjoy having a 12MP dual aperture main camera, a 16 MP ultra-wide camera and a 12 MP 2x zoom camera on rear side.

Fold also has a Front camera on the outside which works as a selfie camera when the device is folded up, more like Galaxy S10.

You can also revel in its dual camera arrangement, internal cameras as you open up the phone. This is an 8MP selfie with sensor for depth. Plus, you have 10MP main internal camera to take your photo capturing to another level. Samsung Galaxy Fold has focused massively on the depth of camera.

Release Date

Although the Samsung Galaxy fold release is made official as announced on 20th February 2019, the new devices will only be available in US on 26th April. In Europe, 3rd May is chosen for its availability.

In November 2018, Samsung previewed the device with Infinity Flex display at its developer conference and was eager and enthusiastic to become the first to bring unique foldable smartphone model to market.

Price anticipation

It might be a little disappointing for people who expect affordable models for Samsung Galaxy Fold. On the contrary, the smartphone is likely to hit retail shops with a price of $1980 in US and €2000 in EU.

Even though you expect the price to be a little higher than straight-designed model, the expensiveness of Fold is justifiable since this is a first-gen piece of hardware design. Samsung proudly boasts being world’s first ever title in Foldable consumer-friendly phone category as DJ Koh says.


Form last year’s teaser to this year’s official announcement on release, Samsung Galaxy Fold has created quite a wave in mobile device market. The main enticing element of Galaxy Fold is the expansive capability of its screen as it moves from the smaller shape to the bigger one. Samsung has especially worked with Google Android developers to develop this flawless feature also known as App Continuity.

Apart from its unconventional design, Samsung Galaxy Fold will continue to create pandemonium in the smartphone market for its outstanding camera provisions, multitasking software support and monstrous memory storage capacity. It is said to be out in May 2019 but we are still anxiously waiting for Samsung to release this phenomenal device in other regions.
