Hi! I built a Faith dash based Christian app in Replit and want to convert it into an App Store and Google play ready app. The entire application is built including Rewards system, Login structure, etc. That said, I am open to suggestions about how to improve it prior to launch. https://stop-and-love-tharris8.replit.app/

We are a small, funded product team taking a live iOS and Android app (React Native) into its most important release. The app is moving from a manual tool to an intelligent, automated daily companion. We are hiring one senior developer to own both the front-end experience and the back-end intelligence layer, and to help us make the key architecture decisions for what comes next. Full product details are shared under NDA. This post is about the bar we need you to clear, so read the application instructions carefully. The One Thing That Matters Most You have personally built and shipped cross-platform mobile apps that real users have in their hands today. Not prototypes, not tutorials, not apps that stalled before launch. We want to see them, use them, and hear exactly what you built. Everything below matters, but nothing matters more than proof that you have taken a mobile app all the way to the App Store and Google Play and kept it running. What You Will Own Front end A polished, animated experience: onboarding flows, sequenced screens, and a completion moment that has to feel premium. We care about craft and detail, not just functional screens. Back end Data modeling, serverless functions, a per-user scheduled notification engine, third-party AI API integration, subscription entitlement logic, and a time-series scoring system. Our current stack runs on Firebase, so you will work in it from day one, but part of your job is to tell us where it should go next. Your first deliverables In your first 1-2 weeks, before heavy building starts, you will: Review our functional spec (FSD) and write the technical spec (TSD) for how you will build it Give us your own build estimate and milestone plan against the October 31, 2026 target. Deliver a written backend recommendation: stay on our current stack, extend it, or migrate. For the backend call, weigh Firebase/Firestore, Postgres (for example Supabase), and other options against our real needs: 10,000+ active users, AI API integration, offline-first sync, reliable push at scale, velocity, and cost. We want an objective read from someone who has shipped on more than one backend, not someone married to a single tool. What You Must Have 3+ years building React Native apps that are live in production on both iOS and Android. Shipped and maintained, not just started. Strong full-stack backend fundamentals: serverless/cloud functions, data modeling, auth, security rules or access control, and API design. Hands-on experience with both a NoSQL database (for example Firestore) and a relational database (Postgres or similar). You should be able to reason about the trade-offs, because you will be advising us on exactly that. Production experience integrating a third-party AI API (Claude, OpenAI, or comparable), including handling latency, cost, and structured output. Proficient in TypeScript. Our codebase is TypeScript. RevenueCat for subscription entitlement management. It is already integrated in our codebase. Push notification infrastructure and scheduled/triggered server logic that runs reliably per user. Clear written English and comfort working async-first over Slack, with GitHub-based code review. Strong Advantage (Not Required) If you have shipped these before, tell us. If not, we expect a strong engineer to pick them up quickly. Firebase at real scale in production: Firestore schema design, Cloud Functions with complex triggers, FCM, and Firebase Auth. UX/UI craft: polished animation work such as SVG stroke animation, radial gradients, and staggered/sequenced motion. Device-native speech-to-text on iOS and Android. Anthropic Claude API specifics: prompt caching, system-prompt engineering, structured output. Experience scaling a consumer or wellness/subscription app to 10,000+ active users. Engagement Time commitment: we expect roughly 20+ hours per week, sustained. This is a real ongoing engagement, not a few hours here and there. Timeline: our v3 release targets October 2026. Expect focused, steady delivery between now and then, with the backend recommendation done in your first few weeks so we can lock the architecture early. Scope: substantial multi-month build with strong potential to continue into v3+ if it is a good fit. We would rather find one reliable partner for the long haul than churn through contractors. Tooling: GitHub, Slack for daily communication, TestFlight for iOS builds. Contract, hourly or fixed-price per sprint. Your preference. Tell us your rate and preferred structure. All builds, schema changes, and deployments are reviewed before release. We commit to a 48-hour feedback turnaround. How to Apply — Read Carefully You must submit a portfolio website or a link to your work before any screening call. Applications without a portfolio link will not be reviewed and will not receive a call. To be considered, include all of the following: A portfolio or work link (required, no exceptions). Applications without one will not be reviewed. One shipped mobile app you are proud of, live on iOS and/or Android, with a store link or video. Tell us specifically what you built. One backend system or serverless function you built. Describe the scale, the data model, and the hardest problem you solved. One example of UI craft or complex interaction, with the visible result (link, video, or GIF). Your one-paragraph read on the backend question: given the needs above, would you stay, extend, or migrate, and why? A confident “it depends, here is how I would decide” is a great answer. A brief note on how you approach scoping and estimating a build like this. We do not expect a number before you have seen the spec, but we want to see how you think about it. Your rate, preferred engagement structure, and realistic start date. How many hours per week you can realistically commit, sustained, between now and an October 31, 2026 v3 target. Be honest. We would rather know your real capacity up front. We respond to every complete application. We are looking for a developer who takes their craft seriously.

Simple Task: *Quick $10 in 5mins *iOS/ android available* *USA only* We are looking for iOS users in the USA to help us test our new social app. The task involves downloading our app, signing up, and trying it out. Then, message us on Upwork about your experience:

Firstly, I want to state that I am not a coder. At all. The code I'd like you to review was entirely "vibe coded" using Antigravity and Claude. I don't intend to create a complete product using this method, in fact, I'd like to use real people as much as possible for my business. I used AI during this phase simply to see my ideas made material. I understand that this means the code itself is likely compromised in all sorts of ways, but I'm hoping that you can help me with that. Please speak with me as you would a fifth grader about the technical aspects of the code, assuming you'd like to work together from this point forward. My app is a free-to-user dating and date planning app that connects people through locally owned businesses. It serves two audiences: - **Singles** looking to meet and go on dates with other singles in their area - **Couples** looking for date night inspiration through a linked accounts mode

Spend 5 minutes a day for 14 days using my app. You accept the invite to be a tested, install the app, create an account and interact with other users. make a couple posts. Like some posts, comment on some posts. This is to meet the Requirement of 14 days of testing for the google play console. You need a Gmail account and android phone. Google will keep track of your testing so it cannot be faked. This app is for a small resort in Ohio. Its to promote our activities and get our guests to post and share with their families.

Capacitor Developer — Publish Existing React Web App to iOS App Store + Google Play OVERVIEW We're an early-stage fintech education startup with a working, production web app (React, hosted). We need an experienced mobile developer to package a FOCUSED version of our app as native iOS and Android apps and successfully publish both to the Apple App Store and Google Play Store. The web codebase is already built and already has Capacitor scaffolding in place. We are NOT looking to rebuild the app — we need someone who can configure, build, test on real devices, and navigate the full app-store submission and approval process for both platforms. IMPORTANT: This is NOT a "wrap the entire dashboard" job. Our web app is information-dense. We want a focused, mobile-appropriate build — a clean, simplified experience (core screens: watchlist, alerts/notifications, a single chart view, and our AI coach chat). We'll provide the exact scope of screens. Building a thoughtful, native-feeling mobile UX matters more than cramming in every web feature. WHAT YOU'LL DO - Configure Capacitor (or advise if a better approach exists) against our existing React web app - Implement a focused set of mobile screens (we'll specify — roughly 4–6 core surfaces) - Set up native push notifications (APNs for iOS, FCM for Android) - Configure app icons, splash screens, bundle IDs, app metadata - Test on real iOS and Android devices - Handle the full submission process for BOTH stores, including responding to review feedback / rejections and resubmitting until approved - Provide a short handoff doc so we can push future updates REQUIRED EXPERIENCE - Proven track record shipping Capacitor (or React Native) apps to BOTH the Apple App Store and Google Play — please share links to apps you've published - Experience navigating Apple App Store review (especially Guideline 4.2 "minimum functionality" for web-based apps — we need this avoided) - Native push notification setup (APNs + FCM) - Comfortable working with an existing React codebase you didn't write NICE TO HAVE - Fintech / finance app experience - Bilingual app experience (our app is English + Spanish) CONFIDENTIALITY REQUIREMENT — PLEASE READ Our app contains proprietary methodology and business logic. Before any access to our codebase or repository, the selected developer must sign our Independent Contractor Confidentiality / Non-Disclosure Agreement (NDA). This is non-negotiable. The NDA includes standard confidentiality and non-compete-on-our-IP terms. Please confirm in your proposal that you're willing to sign an NDA before code access. (Apply freely — you do NOT need to sign anything to submit a proposal; the NDA is only required once we select you and before we share the repo.) LOGISTICS - We will provide: the existing repo (after NDA), the focused screen scope, brand assets (logo/colors), and our Apple Developer + Google Play accounts (or guidance to set them up). - Platform: iOS + Android (both required). - We do not have a Mac — your build setup must not depend on us having one (you handle builds, or use a cloud build service). TO APPLY, PLEASE INCLUDE: 1. Links to 2–3 apps you've shipped to both stores (Capacitor or React Native) 2. A one-line confirmation you'll sign an NDA before code access 3. Your estimated timeline and quote (fixed-price preferred) 4. One sentence on how you'd approach avoiding Apple's Guideline 4.2 rejection

We have a functional location-based social app (#Freedom In Action - FIA) for freedom-oriented communities. It needs a complete modern UI/UX overhaul to feel premium like 2026 apps (dark mode, smooth animations, high engagement). Here is the existing app. https://www.talkingcucumber.com/?wpdmdl=1985 Attached is what I would like the design to look like (I am open for suggestions). I want it fully functional and ready for BETA testing asap. Feel free to make suggestions on design and functionality. I would prefer someone with the same constitutional freedom loving mindset as to prevent any bias or issues.

We are looking to do a new build of our patch bay label designer tool. Customers are currently able to pick their model of patch bay, add text labels, colorize, and group. They can then checkout and it creates print ready artwork for our team to produce. The UI is a bit clunky and there are some features we want to add such as an admin tool to add and edit labels. You can see the current tool here: https://create.traceaudio.com/
