Batch Mix vs Billable Hours Calculator

Batch-Mix is a local-first utility for pressure-washing and soft-washing field work. Enter your batch size, source strength, and target strength to estimate SH and water amounts in gallons or liters. Save mixes with notes on the device, add an optional Surfactant Helper while preserving final batch size, and use the downstream tool to estimate applied strength after an injector. The free app includes the Basic SH/water calculator, unit switching, saved mixes, and limited Surfactant Helper uses. Batch-Mix Pro adds the Field Guide, Advanced Mode, and continued Surfactant Helper access after the free allowance. Subscriptions are optional and managed by the App Store. Any introductory offer is shown only when the store confirms eligibility. Batch-Mix provides estimates and general reference information. It is not a guarantee of cleaning results, a chemical label, or a replacement for product labels, SDS, equipment instructions, local requirements, and testing a small area first.

Billable Hours Calculator turns raw project time into an accurate bill — automatically. Whether you're a freelancer, consultant, contractor, or anyone who bills by the hour, this app removes the guesswork and spreadsheet math from tracking what you're owed. TIME IT TWO WAYS • Start a live timer the moment you begin working — pause and resume anytime, and it stays accurate even if you switch apps or lock your phone. • Forgot to start the timer? Log a session manually down to the exact minute, backdated to any date and time, with an optional note. YOUR BILLING RULES, YOUR WAY • Set a rate per block (e.g. $50 per 15 minutes) for each project. • Choose per-session rounding, where every session rounds up individually, or cumulative rounding, where your total raw minutes are summed first and rounded once. • Add an optional flat setup fee per project. • Set a minimum fee that automatically kicks in if a project's logged time falls under your floor. STAY ORGANIZED ACROSS CLIENTS • Color-code every project so you can tell clients apart at a glance. • See a running total the moment you log time, with a clear line-by-line breakdown of exactly how it was calculated. • Every session — timed or manual — is listed with its duration, date, and note, so you always have a record to back up your invoice. BUILT FOR HOW YOU WORK • Light and Dark mode, matched to your system or set manually. • No account, no login, no subscription required to track your time. Billable Hours Calculator doesn't try to be an all-in-one invoicing suite — it does one thing precisely: turns your logged time into the number you should be charging, exactly the way your contract says it should be calculated.
