We all know that modern world became much more intense than it used to be not so long ago. What that brings up is that there is a number of challenges, our current evolutionary state haven’t coped with yet. Some of them are health issues and today we’re going to look at an assistant, a guide helping to sort out those concerned to diet and nutrition – a mobile application helping to monitor and calculate all things around personal dietary, diet applications as they might be called.

See, diet app development takes a bit more than a simple diary app, despite the similarities. Thing is, nutrition applications are not only logging personal food consumption, bat are also supposed to do some calculations and release some advice. And this is quite a responsibility. Not saying that app development itself is a serious job.

So, if your business is been a dietary expert, it is a good to focus on that side of the job, while you can hire a software company for nutrition app development, based on your dietary expertize.

Now let’s browse through some features we reckon to be must-have in diet application.

They would be:

• Registration

• Diary

• Aggregation page

• Barcode and QR code scanner

• Grocery list

• Native notifications

• External trackers support

• Knowledge base

Registration

First of all, each and every user must fill out a form that would allow to gather most information on user’s physique, in order to start any diet planning and take account of all health and safety issues.

The Short list of those parameters reads:

• Age

• Height and measurements/constitution

• Current weight

• Food allergies/intolerances

• Medical conditions/concerns

Sure, the list goes on to build a proper user’s model, this involves quite a serious bunch of parameters, set by corresponding professionals. Building user’s virtual model exactly is what allows all the forecasting and diet directional witchcraft to work. Registration also allows collection of statistics (according to corresponding laws, for sure) in order to improve the methods and even reach further in the research. And registration is also a must if there is any community element planned.

Diary

During any diet course and often just for the sake of healthy style of living people use food diaries. Since its necessary for proper diet waging, food logger is a required element. A nice touch would be to add a food database to your application along with calories and other nutritional data on each dish, that will ease the logging for the user, choosing from a list is faster than typing, and eliminate typos from the calorie area, thus making in-app calculations more accurate, relying on professionally maintained database.

Aggregation page

The main page of the app – the one that gathers all what matters most throughout whole the application, and displays all that important stuff on a single dashboard. Tat not only is the fast and efficient way of displaying the current status, but also a great navigation tool, since each dashboard area is also a link to the more verbose dedicated app page for its own topic.

Now a small fallback. The main function of the discussed app is nutritional calculations, dietary advice and forecasts, including foreseen weight, body fat levels and measurements. All that based on the registration info, the diary consisting of food logging, water consumption and fitness routines/workloads and immense knowledge and experience of medical and nutritional experts. It surely should have a prominent place on the dashboard, right along with the results already achieved, and a dedicated page containing all the information in a wide view. But is that enough? Based on our mobile app developers’ experience, we reckon there should be one more feature, combining two from the list above, that would highly improve usability and bring the app on a higher level of service and helpfulness.

The shopping assistant

Combining a Grocery list and Barcode and QR code scanner, all that hooked up to the aforementioned food database, with a superb feature of semiautomatic grocery list composing based on those very diet advices discussed earlier, is a good idea for a startup, isn’t it? It would be nice to still allow usual handmade lists and Bar/QR scanner usage, helpful things those, and a choice criteria by chance.

Native notifications

For any real-time apps that have anything to do with regime, notifications are a definitely necessary tool, because busy life needs alerts. Both iOS and Android allow those and have excellent handlers of native notifications.

External trackers support

We cannot talk diets and not monitor activities, because it is crucial for dietary to know not only food and water consumed but the calories spent as well. This is where we have to address to great modern technologies that allow to monitor almost anything we’d like them to. Everything from steps counter and walked distance, to heartbeat rates throughout the day and calories burnt, all that data is available from a vast variety of tracking devices, from FitBit Flex to XiaoMi Mi Band. And don’t forget that since we’re thinking on how to develop a diet app for iPhone and Android smartphones primarily, the app would also have access to their respective developers APIs – Apple HealthKit and Google Health. And they are quite amazing in the job of health monitoring. Both Apple and Google have their own wearables – Apple Watch and Android Wear, they might seem a rare (especially the Apple Watch) when compared to third party tracker bands, but they are present on the market and becoming more and more numerous (especially the Android Wear devices), so the support for them is also necessary.

Knowledge base

The last feature we’d like to discuss today is not just a useful part of an app, but also a feature that distincts a truly thoughtful mobile application from “yet just another project”. Adding a knowledge database, containing important nutritional information, recipes for healthy meals (hooked up with the dietary advisory and the shopping assistant from above), perhaps even a small mobile magazine on topic really makes an app to stand out from the competition.

Finally, how much does it cost to develop a diet app?

First of all it depends on a number of things:

• Android, iOS or a cross-platform application

• Number of features on-board

• Presence of community features

• Presence of in-app purchases

• Width of external hardware support

• And more

As any other mobile application the one dedicated to diet and nutrition would have to pass the following stages:

1. Creating of the technical documentation – the cornerstone of software development

2. Design stage – we would recommend clean not overloaded design

3. Development stage – the longest one in the building part

4. Testing stage – we do want to build a quality product, right?

5. Bug fixing – well, the previous stage gave us this task

So, as an estimate, we can say all these along with project management are going to take around 600 working hours per platform. With the average rates in Eastern Europe $25-$100 we are talking of $15000 to $60000. With all the monetization possibilities of today such project could easily be big. Properly Big.
