For a small business or newborn startup, it’s better to pick the MVP model: a minimum viable product. In your case, that will be the application that has only essential features. This approach reduces costs and development time, which is crucial in terms of the market.  

Second, devote time to research your target audience and competitors. What your clients like and dislike, their pains and desires. While analyzing the rivals, pay attention to their marketing strategy, monetization type, implemented features, brand message, etc. In your IoT app design, you can take into account all the misses made by your competitors and leverage them to your benefit.

Third, we want to point out a crucial detail — monetization. There are several models and the choice will influence your success greatly. It should coincide with your company’s message as well. The most widespread is subscription type, where you offer tiered subscription plans with different features and services for users to choose from. It’s a steady income, but you can also consider pay-per-use, when the charge is based on the actual usage, or advertising, with integrated non-intrusive advertisements or secure sponsorship deals.

Essential IoT app features

The must-have options for a project of this type can vary depending on the specific use case and the type of solution you are developing. However, some common features are:

Device connectivity: of course, your application should be able to connect and communicate with IoT devices securely, either through wired or wireless protocols such as Wi-Fi, Bluetooth, Zigbee, LoRaWAN, or cellular networks.

Data collection: this means gathering data from connected devices in real-time or at regular intervals. It could be sensor readings, device statuses, environmental conditions, or any other relevant information.

Data storage: after collecting, you need to have a secure place for storing the gathered data in a database or cloud infrastructure for further analysis, visualization, and historical reference.

Data analytics: processing the collected information to derive meaningful insights, identify patterns, trends, anomalies, or predictive models is a great benefit of IoT app analytics.

Remote monitoring and control: people should be able to monitor and control their devices remotely through the application, regardless of their physical location.

Alerts and notifications: consider implementing real-time alerts and notifications to inform your clients of critical events or when specific thresholds are met, ensuring timely actions.

User authentication and security in IoT: since the app is connected with sensitive data, you have to incorporate secure authentication and authorization mechanisms to safeguard the information.
