Tally
Why Tally the Perfect:
This name was based on your specific criteria, cross-referenced against competitor software, and vetted for brand feel.
Meets the "Heard Once, Spelled Once" Test: Tally is a common, five-letter, one-syllable word. It is effortless to hear, say, and type on a dirty phone screen.
"Solid and Practical, with Some Weight": Tally carries connotations of accounting, tracking, and completion—the exact core functions of an app that manages estimates, schedules, and invoices. It feels industrious and professional without being corporate.
Modern, Not "Silicon Valley": It is a real word that has been in the English language for centuries, yet it feels fresh and modern when applied to software. It isn't light, cute, or techy.
Trade-Agnostic: Tally does not favor one trade over another. A concrete crew pours, a plumber installs, and they all "tally" their hours, materials, and payments.
The "Anti-Compound" and "Anti-Suffix" Rule: The name stands alone. It doesn't need "Job," "Field," or "-ify" to explain what it does.
