The best expense tracker app for people who hate complexity

Most expense tracker apps were designed by people who love dashboards. This one was designed for people who just want to know where their money went.

The problem with most expense tracker apps

You open the App Store, search for “expense tracker app”, and you’re immediately overwhelmed. Most apps look like Bloomberg terminals. There are tabs, charts, budget categories, investment widgets, bank sync prompts, subscription upsells, and onboarding flows that take 20 minutes to complete.

And then, after all that setup, you forget to use them. Because every time you spend €4 on a coffee, opening the app feels like filing a tax return.

The irony is that the best expense tracker app isn’t the one with the most features. It’s the one you actually use every day.

“84% of people who download a budgeting app stop using it within the first month. Not because the app doesn’t work — but because it’s too complicated to stick with.”

What actually makes a great expense tracker app

After years of trying different tools, the pattern is clear. The best expense tracker apps have three things in common:

• Speed — Log in under 5 seconds. If adding a transaction takes longer than the transaction itself, you’ll stop doing it.
• Privacy — No accounts, no servers. Your financial data is sensitive. It shouldn’t live on a startup’s server you’ve never heard of.
• Simplicity — One screen, everything visible. You don’t need 27 charts. You need to know: how much came in, how much went out.

Why Skei is a different kind of expense tracker app

Skei was built with a very specific person in mind: someone who wants to track expenses without it becoming a part-time job. No bank connections. No subscriptions. No learning curve.

You open the app. Everything is on one screen — your total income, your total expenses, your balance, your categories. You swipe right to add a new transaction. Done. That’s it.

Your data is stored locally on your iPhone and synced via iCloud — no accounts, no servers, no passwords. And it’s a one-time purchase: pay once, use forever. Every update included.

• No Registration — Open and start immediately. No email, no password, no onboarding flow. Just open and go.
• One-Time Purchase — Pay once, yours forever. No monthly fees. No “premium” upsells.
• iCloud Sync — Syncs across all your Apple devices without ever leaving Apple’s ecosystem.
• Face ID / Touch ID — Lock the app with biometrics. Nobody sees your finances but you.

Who is Skei for?

Skei is for people who want awareness, not analysis. If you’ve ever thought “I just want to know where my money is going” without opening a spreadsheet or linking your bank account — Skei is the expense tracker app you’ve been looking for.

It’s especially useful for freelancers and self-employed people who track personal expenses separately from business, for travelers who deal with multiple currencies, and for anyone who has tried and abandoned every other budgeting app because they were too complex.
