I’m building a cross-platform mobile app that lets pet owners record a short video of their sleeping animal, automatically counts breaths per minute with a TensorFlow Lite model, and immediately flags anything over 40 BPM or rising trends. Each new user gets one free reading; after that they subscribe for $4.99/month through Google Play Billing on Android and the corresponding in-app purchase system on iOS. Core flow • Email-and-password sign-up / log-in • Record or upload a 30-second clip • On-device inference (TFLite) returns the respiratory rate • Result screen shows the number and a colour-coded warning if >40 • History tab stores readings locally in Room, then plots them with MPAndroidChart (or the iOS equivalent) so the owner can spot trends over time. Shareable reports. • Automatic email reminders to subscribe. Scope and expectations – Native Android (Kotlin) and native iOS (Swift) or a clean cross-platform approach that still supports TFLite and store-side billing, delivered in 6–12 weeks. – Clean, commented source code in GitHub (or a zipped hand-off) plus a brief README explaining how to update the model, change pricing, and publish future builds. – Working builds uploaded to internal test tracks on both stores so I can review them during development. When you reply, please link to similar apps you’ve shipped, outline your rough timeline/cost, and list any open questions you have about the model, UI, or email service so we can lock the details before kicking off.

Hi there, I will build a robust cross‑platform Pet Respiration Monitor app that lets owners record a 30‑second clip, runs on‑device TensorFlow Lite to count breaths per minute, and flags readings over 40 BPM or rising trends. The app will store readings locally, plot trends, provide shareable reports, and support subscription billing on Android and iOS as you described. I’ll implement clean Kotlin for Android and Swift for iOS (or a tight cross‑platform layer if you prefer), ensure on‑device inference is fast, and save history in a local database with clear visuals. You’ll get well‑commented code, a short README explaining how to update the model, pricing changes, and future builds, plus internal test builds on both stores for your review. I’ll also include a simple, easy update path for the model and pricing, and a ready‑to‑review workflow in GitHub (or a zipped hand‑off). What is the single most critical decision for you: native Kotlin/Swift vs a cross‑platform layer while preserving TFLite and store billing? Best regards,

Hi, This is Elias from Miami. I checked your project description and understand you need a pet health mobile app that records/uploads a 30-second sleeping video, runs on-device TFLite inference to count breaths per minute, flags readings over 40 BPM, stores history, shows trends, and manages subscriptions after one free reading. I’ve worked on mobile apps with ML model integration, in-app purchases, local storage, charts, and user authentication. My approach would be to build native Kotlin/Swift or Flutter depending on model compatibility, integrate TFLite on-device, add secure login, local reading history, trend charts, shareable reports, and App Store/Google Play subscription validation. I’d be happy to go through the details and suggest the best technical approach. I have a few questions to get a better understanding: Q1 – Do you already have the trained TFLite model ready, or should model preparation be included? Q2 – Should readings sync to a backend, or remain local-only on the device? Q3 – Which email service do you prefer for reminders: Firebase, SendGrid, Mailgun, or another provider? Looking forward to hearing from you.

Hi there, I will deliver your pet respiration monitor as a Flutter app — video capture, on-device TFLite inference, subscription billing, and trend charting — with test builds on both store tracks throughout development. For the breath-counting pipeline, I will run frame differencing on the chest region after the user places a bounding box over the sleeping pet. This approach keeps inference lightweight and avoids needing a full pose-estimation model, while still producing reliable BPM readings even in low-light conditions typical of sleeping environments. Questions: 1) Do you already have a trained TFLite model, or will I need to build the respiratory-rate pipeline from video frames? 2) Which email service do you prefer for subscription reminders — SendGrid, Mailgun, or something already in place? Looking forward to talking through the details. Kamran

I’ve worked on a cross-platform health app that processed video input for real-time analysis, including on-device TensorFlow Lite inference. For your pet respiration monitor, I’d suggest a React Native or Flutter solution with native modules for TFLite and billing, which speeds development while keeping platform-specific needs intact. Before starting, could you share the TFLite model size and input requirements? Also, what email service or provider do you prefer for automatic subscription reminders? Knowing this will help set up smooth backend integration without surprises. I estimate a 10-week timeline to cover sign-up, video capture/upload, on-device inference, local data storage with charts, subscription flows, plus internal test track builds and documentation. The quote would include fully commented code and a README explaining model updates, price changes, and publishing. I’m ready to lock down details and get a first iteration running quickly. Let me know how you want to proceed.

Ongoing pet sleep-video monitoring is a real-time on-device ML flow focused on speed and clarity. Your flow (capture → TFLite inference → risk flag + subscription gating) is a mobile architecture problem. I’d use native Kotlin and Swift with shared TFLite, running fully on-device after trimming to a 30s buffer. Results stored locally (Room/CoreData) with charts (MPAndroidChart/Charts) to show trends and rising respiratory patterns. Subscriptions via Play Billing + StoreKit; email reminders via SendGrid or similar. Iterative delivery with internal test builds on both stores to validate model accuracy early from model testing onward. Q1: Expected TFLite input specs (fps, resolution, preprocessing)? Q2: Fully on-device only, or any cloud inference fallback? Q3: Email backend preference (SendGrid, Firebase, or custom)?

I HAVE A QUESTION: Do you have the trained TensorFlow Lite model ready for integration, or is model development part of this scope? Also, for the subscription reminder emails, do you have a preferred third-party service (e.g., SendGrid, Mailgun)? I understand your requirements for a cross-platform pet respiration monitor app featuring on-device AI, subscription billing, and health trend analysis. With extensive experience in mobile app development, integrating machine learning models, and implementing in-app purchases, I’m confident I can deliver a robust solution within your 6-12 week timeline. As requested, here is my relevant experience. One of my recent projects, available on both app stores, was a wellness app that used the phone's camera for real-time health metric analysis. The system supports: - On-device processing with a custom ML model for instant feedback. - Secure user authentication and local data persistence using Room/CoreData. - Subscription tiers managed via RevenueCat to simplify App Store and Google Play billing. This experience is directly relevant to your project, especially with regard to on-device TFLite integration, cross-platform subscription management, and local data charting. My initial timeline estimate is 8-10 weeks, and we can finalize the cost after a brief discussion on the UI/model specifics. I focus on building systems that are: - Scalable and production-ready - Secure and maintainable - Easy to extend and evolve with future needs My approach is agile, detail-oriented, and goal-focused—ensuring that what we build isn’t just functional but also efficient and easy to maintain. Let’s connect and discuss how we can bring your idea to life. Looking forward to it! Best regards, Philip Oyedoyin
