HabitKit's solo app disclosed about $15.1K monthly revenue

Developer Sebastian Röhl disclosed in a 2024 Indie Hackers interview that HabitKit generated about $7,800 in monthly recurring revenue plus roughly $7,300 a month in lifetime purchases, or around $15,100 combined; a New Year peak exceeded $33,000 in one month. The product serves people who want a visual grid for habit tracking. Core features are free, while Pro sells monthly, annual and lifetime access. About 98% of new users arrived directly through the App Store or Google Play, supported by keyword optimization and build-in-public content. A single Flutter codebase delivers iOS and Android, while offline storage removes the need for a backend. The figures are founder-disclosed from 2024, not audited current profit, and omit refunds, store fees, taxes and take-home income.
