I reviewed the application structure. I am implementing a cross-platform wellness application with Firebase: authentication, onboarding, AM/PM reminders, intake logs, streaks, progress, calendar, notes, achievements, and personalized push notifications.

I will build the logic around a single daily state so that morning and evening logs synchronously update the calendar, progress, streaks, and rewards. I will separately configure FCM, event analytics, and data structure for future distributions. Budget and timelines will be discussed in private correspondence.

The design is already prepared in Figma, and does the first release include payment and subscription management through the App Store and Google Play?

Good day. I am developing an application in React Native with push notifications through Firebase, and for the server logic, I am setting up a separate backend on Nest to make the application run faster. I am ready to discuss the details and start working. I would be happy to collaborate.

Good day.
I am ready to take on the development of this application. The application is planned to be native (Android - Kotlin, iOS - Swift). I suggest first developing the Android version, fully implementing the functionality, and then replicating it on iOS.
In terms of timelines - about 2 months. In terms of the total estimate - about 120,000 UAH.
Feel free to reach out if needed!

Hello! I am a Senior Flutter / Full-stack Developer with over 4 years of commercial experience. I develop production applications for iOS and Android, including enterprise, healthcare, and e-commerce products with thousands of active users.
I can complete the project entirely: Flutter client, Firebase backend, Auth, Firestore, Cloud Functions, FCM, Analytics, Crashlytics, and preparation for publication.
I support projects for years, so I lay down scalable architecture, testability, and the possibility of further development.
I use AI orchestration and automated checks to speed up the work, but I personally oversee the architecture and code quality.

The design covers the main scenario, but lacks parts for surveys, authorization, system states, and nested settings. Before starting, we will finalize the complete MVP map; I will reproduce the basic missing states in the existing style.
The estimated cost of the described MVP is 50,000 UAH. The development timeline is up to 4 weeks until the handover of ready builds for review on the App Store and Google Play. In the rate, I include 40 calendar days with a buffer for testing and final adjustments.

I will provide my resume and relevant work samples privately upon request.

Good day.
The application is quite clear; it will require my SQLite + Push Notifications + Payment Subscription experience. I have done similar ones before.
I am a senior mobile application developer and will do it for you efficiently and quickly.
Write to me; if you send the design, we can start today.

A mobile companion app is needed for a wellness brand: onboarding with a survey, AM/PM supplement intake tracker, streaks, achievements, personalized push notifications, and calendar — all on Firebase.

I will create it using Flutter (one codebase for iOS + Android): onboarding with a 5-step survey and saving responses in Firestore, local reminders through flutter_local_notifications with user-defined times, and FCM for personalized push notifications with components. Streaks and progress are tracked in Firestore with daily documents, and achievements are triggered on the backend via Cloud Functions to prevent clients from faking them. For the calendar — table_calendar with colored markers based on the day's status.

A risk to consider in advance: iOS requires a separate entitlement for local notifications and may reject the app if the push notifications do not comply with the Health & Wellness guidelines of the App Store — it's better to prepare a Privacy Policy and descriptions for review right away.

Do you already have a ready UI design in Figma, or should the design be included in the budget?
