Practical guides for personal, family and business expenses

CHEK 2.0.0 is available on Google Play. Personal finances, shared family budgets and business expenses in one Android app.
Free tools
Subscription calculator
See what recurring subscriptions add up to. Enter up to 30 payments in one currency and compare their annual cost, even when billing periods differ.
Savings goal calculator
Enter your target, existing savings and the months available. Get a monthly contribution and compare it with your budget.
Family budget Excel template
Download the spreadsheet, enter your income and plan the month. Compare your plan with actual spending and see the unallocated balance on one sheet.
Personal finances
Expense Tracker App
Coffee on the way to work, groceries for home, a service subscription. Small purchases add up to your month. CHEK helps bring those records into one picture.
Receipt Scanner App
Paper receipts are easy to lose. In CHEK, start with a photo, review the recognised details and keep a record of the purchase.
Budget planner
A budget works best as context rather than a hard restriction. CHEK lets you compare your own plan with recorded purchases, categories and upcoming commitments.
Spending analytics
Knowing your monthly total is a start. Understanding what contributed to it is the next step. CHEK brings purchase records and categories into a spending overview.
Personal finance app
Purchases, receipts, budgets, subscriptions and future goals often live in different places. CHEK brings these workflows together in one Android app.
Savings goals
A plan that only lives in your head is easy to put off. CHEK NEXT lets you give a savings goal its own place and revisit it alongside your spending.
Budgeting with irregular income
When your next payment varies in timing and amount, start with money available now and upcoming commitments. Update the plan after each payment actually arrives.
Family and business
Family Budget · Family OS 2.0
Create a family or join with a code. Review the monthly budget, members’ recorded expenses and remaining amount in one family overview.
Business expenses
Work purchases can get mixed into daily spending. CHEK’s business tools help you organise those records and continue using the data in your own workflow.
Recurring payments
Subscriptions, services and other repeat expenses can disappear among daily purchases. CHEK NEXT gives them a separate place in your planning.
Subscription tracker
Streaming, cloud services, mobile plans and other repeat charges are easy to stop noticing. CHEK NEXT gives recurring payments a separate place in your planning.
Shopping and AI
Smart shopping
What do you need? Which offers are worth checking? Does the price fit your plan? CHEK NEXT brings these questions into a connected shopping workflow.
Price search
A matching product name does not always mean a matching offer. CHEK helps you look for options and return to them before making a purchase.
Market Intelligence
Market Intelligence turns saved receipt items into personal price history. Start with purchases already recorded in CHEK, even when your shopping list is empty.
Shopping list
Keeping the things you need in one place makes planned purchases easier to distinguish from impulse decisions. CHEK NEXT puts the list alongside your spending tools.
Purchase warranties
A saved receipt is useful, but a warranty period is easy to forget. CHEK includes a separate tool for keeping product and warranty information near your purchase records.
AI financial assistant
A page of numbers can leave you with more questions than answers. CHEK AI helps you explore everyday spending and shopping decisions in context.
Financial Brain & Autopilot
Financial Brain brings expenses, budgets, recurring payments and goals into one CHEK 2.0 overview. Review the context behind a suggestion before deciding what to change.
Voice CHEK
Voice CHEK adds speech input to everyday expense tracking. Dictate a short record or type it, check the recognised title and amount, then confirm the expense.
About the app

Explore real screenshots and choose your workflow: personal expenses, family or business. Read the steps behind each scenario below.
Pricing and features
The website calculators and Excel template are free. The Android app provides paid access for ongoing expense tracking, family budgeting and business expense records.
How to use these guides
Worked examples explain a calculation, not a recommended level of spending. Substitute your own amounts and check payment dates. App features are separate from the website calculators: figures entered here do not transfer automatically into CHEK.
App and feature availability can vary by country, version and data source. Price search does not guarantee coverage of every retailer. Check device compatibility and installation availability on Google Play.
