Description

Invoice by Alto (now delivered through the Alto Timer app) is a mobile-first billing tool for solo workers — freelancers, contractors, consultants, designers, musicians, and trades — who want to run a one-person business from their phone. It combines one-tap time tracking, expense/receipt logging, and invoice creation with payment collection via CashApp, PayPal, Bitcoin, and Maya. Its main differentiator is the 'Alto Price Guarantee': free for the first three months, then a locked-in 99¢/month rate that never rises.

Clockk is an AI-driven automatic time tracker for professionals who constantly switch between projects and clients, running in the background to attribute your work to the right project without manual timers. It's aimed at freelancers, small agencies, and service firms (web designers, developers, media shops) who bill by the hour or by project and need accurate, defensible time data. Its main differentiator is that it captures time passively and is explicitly positioned as a non-surveillance tool, so you keep control over who sees your activity rather than being monitored.
