Coming Up With Ideas For “The Next Big App” By Solving Real-World Problems

Mobile (iPhone / Android / Windows) Apps can be utilized to solve communication problems.

  • Suppose two persons, A and B, share the same route to work each day. We can develop an app that helps them connect and share a car.
  • Or we can develop an app that connects used textbook sellers and textbook buyers (bit like Chegg [1]).


So if a group of people share a common interest or can be connected to solve a problem (but they are not friends on Facebook or not in one anothers’ contact list and not aware that they share the problem), then we can design apps that connect them and solve the problem.

Your app has to solve a narrowly focused problem and solve it well.

Uber, Airbnb follow the “Finance” Model.

Some people have excess of some resource and others need that resource. So the resource is being transferred from the provider to the needy “for efficiency” “on some conditions”.
In Finance, it’s transfer of money, through Banks, Bonds and Stocks.

Some people have excess of money that they don’t know how to make best use of. Others need money to bring a product to market or buy a house. So, Banks collect money from people who have excess of it, and lend it to borrowers who need it.

  • Uber [2] – transfer of ride space.
  • Airbnb [3] – transfer of house space.


So what are your ideas for the “Next Big Smart Phone App” that really solve real world problems?

Looking Back And Connecting The Dots

Sometimes, it seems amazing when you look back at time and try to connect the dots

I came back to America last November (2011) with a newly found interest in Biology and BusinessFor me, one of the best things about living in America at that time was fast Internet connection. When you have fast internet connection, you do stuffs that you wouldn’t do otherwise. For me, it was downloading books – thousands of them!If I find a subject area or topic interesting, I usually try to learn as much as I can from books and the web. Then while learning about the topic, whenever I come across a new topic that I find interesting, I start following the same procedure

for the new topic of interest (recursively; if you prefer Computer Science terminologies!) – serendipity in action! 

I have always been fascinated by the prospects of improving health and brain power. Previously, my idea was to invent new technologies (e.g., stem cells, engineered organs etc.) for better health and more brain power. Books and ideas (e.g., human body version 2.0) of Ray Kurzweil and others have always inspired me. 

My interest in Biology led me to books – which helped me discover that both health and brain power can be improved dramatically by natural means. Reading those books, I became aware of the benefits that a sound health can bring into your life. I incorporated a lot of health practices to my life. A lot actually – 

  • aerobic exercises and strength training 
  • mindfulness and deep breathing 
  • lots of blueberries and strawberries and nuts and yogurt 
  • and a whole lot of other changes in my diet plus supplements 

My quantifiable success – I lost about 40 pounds in a span of 6-9 months (from 192/194 to around 150)! 

My interest in Business, besides showing me ways to handle social problems in more elegant ways, led me to an advice: “Isolation is dangerous”. So I made myself a lot more social than I was.

Then, being social and conversing with others (time period: December 2011 – March 2012), I found out that I could actually think a lot better than I thought I did and I was amazed.

I was amazed at how much I had managed to learn by myself. I have never had the opportunity of learning from very good teachers or very smart peers (excluding a few days during Math Olympiad back in 2005). I had no one to guide me. I learned to guide myself.

I was inspired.

So when I came back to Bangladesh in March 2012, my inspired self returned to unsocial life spending time on nerdy stuffs!

Now, I am eagerly waiting to find out where my previous experiences take me next. 

Life is never this simple. I have left out a lot of details. But this is surely an outline.

What Makes Some Ideas Survive

The qualities of an idea that make them survive and stick to everyone’s mind according to “Made to stick: Why some ideas survive while other die”

  1. Simplicity
    • Simple = core + compact.
    • A successful defense lawyer says, “If you argue ten points, even if each is a good point, when they get back to the jury room they won’t remember any.”
    • We must create ideas that are both simple and profound. The Golden Rule is the ultimate model of simplicity: a one-sentence statement so profound that an individual could spend a lifetime learning to follow it.
  2. Unexpectedness
    • We can use surprise—an emotion whose function is to increase alertness and cause focus—to grab people’s attention.
    • For our idea to endure, we must generate interest and curiosity.
    • We can engage people’s curiosity over a long period of time by systematically “opening gaps” in their knowledge—and then filling those gaps.
  3. Concreteness
    • Naturally sticky ideas are full of concrete images—ice-filled bathtubs, apples with razors—because our brains are wired to remember concrete data.
    • Speaking concretely is the only way to ensure that our idea will mean the same thing to everyone in our audience.
  4. Credibility
    • We need ways to help people test our ideas for themselves—a “try before you buy” philosophy for the world of ideas. 
    • When we’re trying to build a case for something, most of us instinctively grasp for hard numbers. But in many cases this is exactly the wrong approach. In the sole U.S. presidential debate in 1980 between Ronald Reagan and Jimmy Carter, Reagan could have cited innumerable statistics demonstrating the sluggishness of the economy. Instead, he asked a simple question that allowed voters to test for themselves: “Before you vote, ask yourself if you are better off today than you were four years ago.
  5. Emotions
    • How do we get people to care about our ideas? We make them feel something.
    • Research shows that people are more likely to make a charitable gift to a single needy individual than to an entire impoverished region. 
    • Sometimes the hard part is finding the right emotion to harness. For instance, it’s difficult to get teenagers to quit smoking by instilling in them a fear of the consequences, but it’s easier to get them to quit by tapping into their resentment of the duplicity of Big Tobacco.
  6. Stories
    • How do we get people to act on our ideas? We tell stories.
    • Research shows that mentally rehearsing a situation helps us perform better when we encounter that situation in the physical environment. 


Marketing Principles From Seth Godin

How to get your ideas spread
  • Be remarkable. Make people make a remark! So many competitors and advertises out there and so less time for customers. The only way to catch attention is being remarkably different.
  • Reach Innovators and early adopters who are willing to listen first. They will spread your idea. Average customers just follow the trend. Reaching early adopters is the key.

Gamifying The Process Of Achieving Goals

Introducing game mechanics into the process of achieving goals.

Determine the Goal.

  • Typical Goals:
    • Life Objectives.
    • Compete. Compare yourself to others. Beat others! You don’t have to take part in a competition. You might just figure out what a person is good at and try to be better than him. In the process become better at something.
    • How do I build that product. What are the skills I need to master. How do I build everything that company has ever built.

Creative Visualization + Faith

  • Creative Visualization:
    • Visualization and Appreciation of how it feels like to turn the goal into reality.
  • Faith:
    • Strong belief that the goal is very much within reach. You can almost see how to achieve it.
      • Go through your past successes and accomplishments.
  • Now you have a burning desire to achieve the goal.

Think backwards from the goal to present situation and find out requirements that lead you to the goal.

  • Make a plan.
  • Make a list of sub-goals that lead you to the main goal.

Start working.

Measure how much you have achieved and how much closer you are to the goal at regular time intervals. Use them as feedback. Success, progress pushes you just as getting closer to your desired goal does.

  • Make the whole process similar to the games you have played. Suppose, you are playing a game, and you have earned say, 70 points (Yay!) and you need 30 more (pretty close!) to reach the next level. Exciting, huh?
  • Use feedback to your advantage.
  • Hey, that part is taking me too long to finish. What can I do to make things faster?
  • In the process, become a master.

Associate positive feelings with the task at hand.

  • Feel happy while you are doing it. Feel happy when you think of it.

Go back to step 2 whenever you need little bit of extra motivation.



Product Management In Brief

Integrating different departments:

  • Research & Engineering: What’s possible
  • Design: User Interface & Experience (user, gadget, environment, software) design
  • Marketing & Strategy: What customers / consumers want? Competitors? Use Data analytics.
  • Integration: Using some form of collective mind map that depicts all of the different components of the product in which everyone in the team can contribute.


  • Design
  • Prototype
  • Test & Get user feedback
  • Develop & Get user feedback & Employ Data Analytics


  • Working backwards from goal theoretically and starting with the features other parts most depend on (Topological sorting).
  • Utilization of Operations Research models.

Human Resource Management & Team Management:

  • Smart people want to innovate. Encourage them so that they can come up with innovative solutions in every step of the process and share with others.
  • Gamify. Points, Badges, “Most innovative engineer” etc.
  • Make sure all the team members really care about the product – startup like environment, enthusiasm.
