TL;DR
Track revenue, store fees, and costs across your apps in a simple system. Your real profit is what is left after the store cut and your expenses, so log those, set aside money for taxes, and review monthly.
An app business can feel profitable while quietly earning less than it looks. Your dashboard shows a nice gross revenue number, but once you subtract the store cut, any paid APIs your app uses, and your developer fees, the real profit can be far smaller than the headline. I'm David, and tracking my numbers is what turned a fuzzy side project into a business I could actually make decisions about. You do not need anything fancy to start.
Record your real profit, not the gross
The number that matters is what you actually keep, not the gross revenue on your dashboard. Real profit is your revenue minus the store cut - 15 percent on the small-business program or 30 percent standard - minus any service costs and your developer fees. When you log a month, capture all of those so your numbers reflect reality. Tracking only gross revenue makes you feel richer than you are and throws off every decision.
Log costs and fees too
Your revenue is only half the picture. The store cut, any paid APIs or services your app calls, your Apple and Google developer fees, and tools you pay for all eat into profit, and in many places genuine business costs matter for taxes too. Keep a simple running log of what it costs you to run each app, with receipts where you can. Even a basic record makes tax time easier and shows what your apps really net.
- Log revenue, store fees, service costs, and developer fees per app
- Calculate real profit as revenue minus the store cut and all costs
- Set aside a portion of profit for taxes as payouts land
- Review your numbers monthly so nothing piles up
Keep it simple at first
You do not need accounting software on day one. A single spreadsheet with columns for app, month, gross revenue, store cut, costs, and profit covers most builders early on. What matters is consistency - updating it every time a payout lands or a cost hits. As your business grows you can move to dedicated tools, but a neglected fancy tool is worse than a simple sheet you actually keep current.
Use the numbers to make decisions
Tracking is not just defensive. Clear records show which apps make the most profit, which cost more to run than they earn, and whether your income is trending up or down. That insight is how you decide which app to improve, which to sunset, and when you can afford to scale or go full-time. Numbers you actually look at turn app building from guesswork into a business.
Start tracking from your very first payout. It is far easier to keep clean records from the beginning than to reconstruct a chaotic year at tax time. A simple, consistent system pays for itself many times over.
Common questions
What number should I record as profit?
Record real profit: your revenue minus the store cut, minus service costs, minus your developer fees. The gross revenue on your dashboard alone overstates what you keep. Your real profit is what actually lands after Apple's or Google's cut and every expense is counted.
How much should I set aside for taxes?
The right percentage depends on your country, income level, and situation, so this is general guidance rather than tax advice. The important habit is separating a portion of your profit into a dedicated account as payouts land. Check with a qualified tax professional for your situation.
Do I need accounting software to track my numbers?
Not at first. A simple spreadsheet with app, revenue, store cut, costs, and profit covers most builders early on. Consistency matters more than sophistication. You can move to dedicated tools as your business grows, but a sheet you actually keep current is enough.
What costs should I be tracking?
The store cut, any paid APIs or services your app uses, your Apple and Google developer fees, and tools you pay for - all of it eats into profit. In many places genuine business costs also matter for taxes. Keep receipts and log them, and confirm what qualifies where you live with a professional.
How often should I update my records?
Ideally every time a payout lands or a cost hits, and review the whole picture monthly. Updating as you go prevents a chaotic scramble at tax time. A simple system you keep current beats a sophisticated one you neglect and have to reconstruct later.
Why track numbers beyond taxes?
Clear records show which apps are most profitable, which cost more to run than they earn, and whether income is trending up or down. That insight guides which app to improve, which to sunset, and when you can scale. Tracking turns app building into a real business.
