Because the tools freelancers have today weren't built for freelancers.

Push notifications 30, 14, 7, and 1 day before every IRS quarterly payment — with your exact amount already calculated.

All calculations happen on your device. No accounts, no servers, no trackers, no data brokers. Ever.

Every tax term explained. Every deduction categorized. Built for real humans, not CPAs.

Built for freelancers, contractors, gig workers, and the self-employed — not generic personal finance.

We're launching on iOS and Android in the coming weeks. Early subscribers get a founder's discount on SoloCalc Pro.
