Machine Learning: Enhancing App Features and Personalization

Machine learning (ML) is a way for apps to “learn” from data—improving their performance or accuracy over time without being explicitly reprogrammed.

Why It Matters

Why Founders Should Care About This Term:

• Enables smarter, more personalised user experiences.
  
• Automates decision-making, saving time and manual work.
  
• Improves prediction accuracy for things like recommendations or fraud detection.
  
• Makes your app stand out with innovative features.
  
• Helps scale efficiently as data grows.

Use This Term When...

• Planning features like recommendations, personalisation, or fraud alerts.
• Deciding how to leverage user data for better insights.
• Discussing app scalability and automation.
• Exploring AI-powered capabilities in your roadmap.
• Collaborating with data scientists or AI vendors.

Real-World Example

In one of our projects, we implemented machine learning to personalise content feeds based on user behaviour. This led to a 35% increase in engagement and time spent in the app.

Founder Insight 

Founders often want to “add AI” without knowing what data they need. ML is only as good as the quality and volume of data it’s trained on. Start collecting structured data early.

Key Metrics / Concepts 

• Model Accuracy – How correctly the ML algorithm makes predictions.
• Training Data Size – The amount of data used to train the model.
• Precision and Recall – Metrics that measure how well your model identifies true positives vs false positives.
• Overfitting – When a model is too tailored to training data and performs poorly on new data.
• Inference Time – How quickly an ML model returns results in real-time use.

Tools & Technologies 

• TensorFlow / PyTorch – Popular frameworks used for training and deploying ML models.
• Firebase ML Kit – Google’s ML tools tailored for mobile apps.
• Amazon SageMaker – Used for building and managing machine learning models at scale.

What’s Next / Future Trends

Machine learning is becoming more real-time, edge-enabled (on-device), and explainable. Privacy-preserving ML and federated learning will also shape how apps deliver smart experiences without risking user trust.
