The Mobile App Business with Fexingo: iOS, Android, and Consumer App Companies

In this episode, Lucas and Luna dive into how mobile apps leverage on-device AI for real-time food recognition. They explore the technology behind apps like Yuka and Calorie Mama, which use computer vision models to identify food items from a camera feed. Lucas explains the shift from cloud-based to on-device processing, citing Apple's Core ML and Google's ML Kit as key enablers. They discuss how apps achieve low-latency recognition without sending images to servers, preserving user privacy. Luna brings up the challenge of handling diverse cuisines and the need for large, varied training datasets. The hosts also touch on practical use cases: calorie tracking, allergen detection, and dietary logging. Lucas notes that on-device food recognition is now accurate enough for meal logging but still struggles with mixed dishes and portion size estimation. The episode concludes with a look at future improvements, including incremental learning models that adapt to a user's eating habits over time. A natural donation segment is woven in, reminding listeners that the show stays ad-free thanks to their support.

Episode 104 of The Mobile App Business explores how consumer apps are turning privacy policies from dense legal documents into trust-building tools. Lucas and Luna examine the shift toward plain-language disclosures, on-device data processing, and granular user controls, using Apple's App Tracking Transparency and Signal's minimal-data approach as case studies. They discuss the business trade-offs: transparency can reduce ad revenue but increase user retention and lifetime value. Specific data points include the 40 percent opt-in rate for ATT and the 25 percent higher retention rates reported by apps with clear privacy labels. The episode also covers emerging regulations like the EU Digital Markets Act and how startups can compete on privacy without a massive compliance budget. Listeners will learn one practical way to audit their own app's data practices and why 'privacy-first' is becoming a competitive moat in 2026.

Imagine being on a phone call in a crowded coffee shop and the other person hears only your voice, not the espresso machine or the chatter around you. That's on-device AI voice isolation, and it's quietly becoming a standard feature in mobile apps — from Zoom to WhatsApp to Apple's FaceTime. In this episode, Lucas and Luna dive into how this technology works, why it's happening on-device rather than in the cloud, and what it means for privacy and audio quality. They break down the specific neural network architecture — a U-Net with a spectral masking layer — that can separate voice from noise in real time, using only the phone's neural engine. They also discuss a surprising use case: podcasters recording interviews in noisy environments, and how apps like Ferrite and Descript are leveraging this. Plus, a quick look at the hardware race between Apple's Neural Engine and Qualcomm's AI Engine. If you've ever struggled with background noise on a call, this episode explains the tech that's solving it — and why it matters for the future of mobile communication.

In this episode of The Mobile App Business with Fexingo, Lucas and Luna explore how consumer apps are using on-device AI to recognize emotions in real time. They focus on the technology behind facial expression analysis, the privacy advantages of processing data locally, and a specific case: how a meditation app uses emotion cues to customize sessions. Lucas explains the shift from cloud-based emotion AI to on-device models, citing Apple's Neural Engine and Google's TensorFlow Lite. Luna raises concerns about accuracy bias and user consent. The conversation drills into one concrete number: 85 percent accuracy for basic emotions in controlled settings, per a 2025 Stanford study. They also discuss how app developers balance personalization with avoiding creepiness, and why some users opt out. A grounded look at a quietly growing AI use case in your pocket.

Episode 100 of The Mobile App Business explores how mobile apps are using on-device AI to enable real-time eye tracking without cloud latency or privacy risks. Lucas and Luna break down the technology behind Apple's Eye Tracking feature in iOS 18, which relies on the TrueDepth camera and the Neural Engine to let users navigate with just their eyes. They discuss how this opens up accessibility for people with motor disabilities, and how the same technology is being adopted by gaming apps, productivity tools, and automotive interfaces. The hosts also cover the business implications: why on-device processing makes eye tracking scalable, how developers can integrate Apple's framework, and what the future holds for gaze-based interaction.
