Fin AI says

Your food budget is tighter than usual because two restaurant charges landed before the grocery run. You can still spend $55 per day through month end.

Launch auth path

Google, Apple, and email sign-in are part of the real app flow.

The homepage now points users to the correct platform while the app keeps the auth model users expect: Google OAuth, Apple Sign In on iOS, and email/password for direct account access.

Google

Continue with Google

Web and native Google sign-in use the configured Fin Google OAuth clients and backend provider-session validation.

Apple

Sign in with Apple

iOS builds declare Apple Sign In for bundle com.heyyykk3.fin and use the app callback path.

Email and password

Users can still sign in directly in the mobile app with the Fin account flow.

Routing

Device-aware entry

Android users go to Google Play testing, iPhone users go to the App Store, and desktop users go to web login.

Modified web app, not a new app

The desktop version should be the same Fin app with a wider frame.

The source app already switches to desktop behavior above tablet width: a persistent sidebar, wider dashboard grids, desktop transaction filters, and centered modal workflows. This site now presents that architecture plainly.

Desktop shell

Left navigation, account footer, settings access, and route groups match the existing Expo web layout.

Real finance jobs

Dashboard, transactions, budgets, subscriptions, AI help, goals, friends, and split groups stay together.

Multi-desktop path

The same web build can be packaged later for Mac, Windows, and Linux without changing the product model.

Working preview

Click through the desktop workflows.

The preview below is static data, but the interactions are real. It mirrors the parts of Fin users expect on desktop: sidebar navigation, dense summaries, transaction review, AI answers, and split balances.

Dashboard

Know the number before you spend.

Balance, bills, goals, and recent activity turn into a safe-to-spend read for the rest of the month.

Platform plan

Multi-platform without splitting the product.

Fin keeps one product surface and adapts the entry point. Android gets Google Play testing, iPhone gets the App Store, and desktop gets direct web login.

Web

Desktop login

Desktop visitors can enter the web app directly instead of being sent through a phone download flow.

Real app screens

The desktop page is grounded in the mobile product.

These are app screenshots from the current Fin surface. The desktop shell keeps the same product jobs, then gives them more room.

Fin dashboard showing balance, safe-to-spend, AI insight, goals, and recent transactions — **Dashboard**Safe-to-spend, goals, cash flow, and recent activity.

Fin transactions list with monthly summary, search, filters, categories, and add transaction controls — **Transactions**Search, filters, month view, categories, and review.

Fin AI chat screen with suggested finance questions and assistant answers — **AI Chat**Ask about spending, receipts, budgets, and next actions.

Fin analytics screen with financial health, cash flow, and category trends — **Analytics**Cash flow, financial health, category trends, and timing.

Fin split groups screen with group balances and shared expenses — **Split Bills**Groups, balances, expenses, settlements, and friends.

Trust and readiness

Desktop finance software has to feel direct, not decorative.

Fin keeps the sensitive work explicit: the assistant explains, the user approves, and private numbers stay inside a focused app frame.

Manual-first tracking

Reliable launch workflows before bank import: transactions, budgets, goals, and split expenses remain user-controlled.

AI with confirmation

AI can explain, prepare, and summarize, while deletes, settlements, and account-impacting changes remain gated.

Responsive frame

Mobile stays compact. Desktop gets more scan-friendly density without creating a second app.
