Wellii: Simple Wellness App Development

Hi! I’m looking for a reliable and experienced mobile app developer to build a clean, simple, and useful wellness app called Wellii — for both iOS and Android.

This app will be powered by ChatGPT (OpenAI API) and focused on daily emotional check-ins. It must be light, calming, and habit-forming — with no unnecessary features.


---

App Concept:
Wellii is a minimalist mental wellness app where users:

Check in with how they feel

Receive a short, personalized AI-generated message

Optionally continue the conversation with a calm, supportive AI


No account. No login. No cloud. All data stays local on the device.


---

App Must Include:

3 Core Screens:

1. Mood Check-In



User taps emoji or types short text

No popups or extra steps


2. AI Response Screen



Uses OpenAI API to respond with a supportive, thoughtful message

Based on mood input


3. Short AI Chat



User can send up to 3 messages to the AI per day (free)

After that: show AdMob ad or prompt upgrade

Other Required Features:

AdMob integration (banner and optional interstitial ads)

No login / no backend (local data only)

Clean, calming UI

Push notification (daily check-in reminder)

App icon

Splash screen

App submission (Google Play + App Store)

Full source code included
