Flip, the cheeky gold coin, giving a thumbs-up on a theatre stage

Flip saysI only flip for style. The answer is already decided: wait.

How it works

Three steps, a few seconds, one answer.

  1. Snap, paste or say it

    Point the camera at a shelf tag or a receipt, paste a product link, or just ask out loud.

  2. It checks the market

    Other stores with delivery counted in, and what the price did over the last 90 days.

  3. It checks your money

    Your income, payday, bills, goal and balance decide what is safe to spend. Then your buddy gives the verdict.

Buy or wait?

Four verdicts. No maybe.

Every check ends in one clear answer, with the evidence right underneath.

  • Buy now

    The price is good and it fits your money. Go for it.

  • Wait

    It usually gets cheaper, or a sale is coming. Your buddy can remind you.

  • Buy elsewhere

    Another store has it for less, delivery included.

  • Not this month

    It would eat into your bills or your goal. Try again after payday.

The five

Meet the five

Same rules, different voice. Pick the one you like and switch any time.

  • Flip in their room

    Flip

    The cheeky gold coin

    Cheeky, quick and a show-off. Small and proud of it.

    “I only flip for style. The answer is already decided: wait.”

  • Vault in their room

    Vault

    The steel safe on guard

    Disciplined, loyal and firm. Says no without drama and yes without fuss.

    “Over budget this month. Request denied. The safe stays shut.”

  • Jingle in their room

    Jingle

    The little glass money jar

    Sweet, cheerful and easily amazed. Celebrates every small win.

    “We saved six coins! Six! Listen!”

  • Digit in their room

    Digit

    The calculator robot

    Literal, helpful and proud of accuracy. Apologises for rounding.

    “Saving detected. I rounded the result slightly. I apologise for the rounding.”

  • Baron in their room

    Baron

    The rich, angry ogre

    Loud, impatient and greedy for bargains. Bullies prices, never people.

    “Full price? I did not get rich paying full price!”

Choose a humor level, from gentle to roast. They joke about prices, never about you.

What it checks for you

The homework you would do before buying, done in seconds.

  • Other stores

    The same product at stores in your country, with delivery counted in the total.

  • Price history

    The 90-day low and high, so you know whether today’s price is a good one.

  • Your safe-to-spend

    What is left until payday once your bills and your goal are covered.

  • Cheapest split

    Tell it your shopping list and it finds the cheapest way to split it across stores.

  • Price alerts

    Track something you want and hear when it drops, reaches your target or is back in stock.

Privacy

Your money stays your business

In plain words, from our privacy policy:

  • No bank login. Ever.

    You type or say your income, bills, goal and balance. We never ask for your bank login, card numbers or account numbers.

  • Photos are not kept

    A receipt or tag photo is read for its items and prices. The image itself is not stored: only the items and prices you keep.

  • Where your data lives

    On your phone, and synced to servers in the European Union (Frankfurt) when you sign in to an account.

  • Not for sale

    We do not sell your data and we do not show third-party ads based on your money.

  • Yours to take or delete

    Download everything in one file, or delete your account and its records, at any time in the app.

Questions

When can I get CoinKin?

We are finishing the app for iOS and Android. Leave your email at the top of this page and we will write when it is in the stores.

Is this financial advice?

No. CoinKin gives budgeting and price information only: no investment, credit, tax or legal advice. You always decide what to buy.

Do I need to connect my bank?

Never. You type or say your numbers yourself and update your balance when you like.

Which countries and stores does it cover?

It works in any country and currency. Your country sets the currency and the stores it checks, and the stores covered differ from country to country.

Are the voices real people?

No. The mascots are AI characters with synthetic voices. They joke about prices at the humor level you pick, never about you.

What will it cost?

There will be a free plan. Plus and Pro are planned at $9.99 and $19.99 a month before VAT, and new users get seven days of Plus. The stores show the final price.

Who is it for?

Adults. You must be 18 or older to create an account.
