SideProfit helps you see whether a small project is actually becoming profitable. Track revenue, expenses, time cost, and break-even progress for every app, SaaS, side project, or product experiment you are building. Instead of guessing whether a project is working, SideProfit shows the numbers that matter: income, costs, net profit, hidden development time, and how far each project is from paying for itself. Built for solo founders, indie developers, app makers, SaaS builders, creators, and small teams managing real projects with real costs. What you can track: - Income from app sales, subscriptions, payouts, sponsorships, or other project revenue - Expenses like hosting, APIs, domains, design, ads, tools, App Store fees, and AI services - Time spent on each project, with an estimated hourly rate - Break-even progress before a project becomes profitable - Long-term revenue goals after a project reaches break-even - Monthly revenue and expense trends - Net profit across one or more projects SideProfit is not a personal budget app or full accounting system. It is a focused project profitability tracker for people who want to know whether a small project is turning into something real.
