The program will be very simple:
Although the algorithm is simple, the implementation of each step can make this app very useful. For example, in steps 1 and 2, I can communicate through different channels: keyboard, voice, or messaging apps.
I can also alter the algorithm itself, for example, to make it death-proof: if your computer shuts down during step 4, it needs to know what it has to remind you about. But for now, let’s stick with the simple stuff.
I make a simple thing: take every step of our algorithm and show how it can be implemented in Python. First, though, I need to get things ready. Here is a Python command that I need to use:
Import tells Python to load a module with the tools that I need for the task. Time is the name of the module. From that module, I’ll need a method called ‘sleep’ that I’ll use to pause the program for a set amount of time
I need to ask the user and get a response. In a perfect world, I’d want a code like this:
reminder = user.ask("What shall I remind you about?")
And somewhere in the program, I’ll need to define what user and ask mean. It may be a message sent over Telegram, or it could be a voice prompt, or maybe have a robot approach user with a happy face and display the message on the screen. Implementation could be different, and I’d define it in a separate place in our program.
But I want a simple implementation, so I’ll go with some built-in commands:
print("What shall I remind you about?")
Print sends out a text message into Python’s default output (which in our case is command line).
text = str(input())
Take whatever the user has written, think of it as text, and put it into memory under the name “text”. Input() reads whatever the user inputs. Str() turns whatever had been input into text. Equals means “put one thing into memory with such name.”
I need time in minutes. Here goes:
print("In how many minutes?") local_time = float(input())
The second line means: Take whatever user typed, think of it as a number, put it in memory under the name “local_time”.
I have a number of minutes that our app needs to wait before reminding us. But Python’s time.sleep() method requires seconds, not minutes. So I need to convert minutes to seconds:
local_time = local_time * 60
This reads: take whatever is in memory under the name “local_time”, multiply it by 60, and put it in memory under the name “local_time”.
Now I’ll need that time module that I loaded in step 0:
This reads: From module “time,” take the method “sleep.” From memory, find a piece of data under the name “local_time.” Give that piece of data to “sleep” and see what happens.
What happens: I have a number of seconds in ‘local_time’. I give that number to ‘Sleep,’ and the program sleeps for the specified number of seconds. I know it sleeps because I had read the reference manual for the module’ time’.
Remember that I have our reminder text stored in memory under the name ‘text’? It’s time to use it:
This means: take whatever is in memory under ‘text’ and send it to output.
Similar to step 1, U could have set up a whole different implementation of sending out messages. I could have created a routine that 3D-prints our message in plastic or lights up some LEDs in the form of our text. But all I need now is this primary mechanism that sends out the text.
This is the code that will work:
import time print("What shall I remind you about?") text = str(input()) print("In how many minutes?") local_time = float(input()) local_time = local_time * 60 time.sleep(local_time) print(text)
If you input this into your Jupyter notebook and run (Shift + Enter), you’ll see your program in action:

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.
Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.
There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.
To give you an idea of how long the app development process takes, here’s a short guide.
_Average time spent: two to five weeks _
This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.
All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.
Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.
The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.
The outcomes of this stage are app prototypes and the minimum feasible product.

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?
Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.
Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.
To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.
What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.
You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.
Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.
You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.
You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.
As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.
Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.
As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.
All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.
This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!
Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.
Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.
What advantages can you get from micro-mobility? Let’s take a deeper look into this question.
Micro-mobility can offer several advantages to the people on your campus, e.g.:
