About
Simple apps for the jobs you'd otherwise do in a spreadsheet.
WebPlannerCo. makes small, focused web apps for everyday planning, weddings, budgets, mortgages, freelance work and more. The kind of thing people usually build in a spreadsheet, rebuilt as a clean app that just works.
Why we build these
Spreadsheets are powerful, but they're fiddly and fragile, a wrong formula, a deleted row, a tab you can't quite remember the logic of. For most everyday planning, that's more effort than the task deserves. We take the jobs people repeatedly wrestle into spreadsheets and turn them into purpose-built apps: the budget already adds up, the guest list already tallies, the mortgage already models the what-ifs.
You can use them free of installs in any browser, and either download a copy to own outright or sign in for cloud sync across your devices. No app store, no setup, no spreadsheet to maintain.
What we care about
One job, done well
Each app is built for a single task, not a blank template you have to wrestle into shape. Open it and the structure is already there.
Your data stays yours
The tools run in your browser. Your planning data is saved on your own device by default; the optional online version syncs it to your account so it's on every device.
Own it, or sync it
Buy an app once and download it to keep, no subscription, works fully offline. Or use it online with cloud sync for a small yearly fee. Your choice.
No spreadsheet maintenance
No formulas to fix, no broken references, no fragile tabs. The maths and layout are handled, so you can just plan.
Who's behind it
WebPlannerCo. is built and operated by SIG Machine Learning Pty Ltd (ACN 637 894 690), a software company based in Australia. We design, build and support every app ourselves, and we're steadily adding new ones, there's a range of tools already on the way for finance, property, freelance work and travel.
Got an idea for a tool, or feedback on one you use? We'd genuinely like to hear it.
