Answers

Short, direct answers to the questions founders ask.

How to pick the right free tool

The tools are grouped by the stage you are at. If you have an idea and no app yet, start with the app development cost calculator and the idea validator. If the app is live and downloads are slow, the ASO score and the listing checker show what the store page is missing. If you are buying users with ads, the ROAS, CPA and cost per lead calculators tell you whether the spend pays back, and the subscription LTV calculator tells you what you can afford to pay per install. Dental practices have their own set at tools for dental practices.

Every calculator works the same way: change a number on the left, the result updates on the right, and the verdict under it says what the number means and what to do next. Nothing is stored unless you ask for the result by email.

Questions people ask

Are these marketing calculators really free?

Yes. No signup, no trial, no card. The two AI report tools ask for an email before the full report because each run costs us money to generate; every calculator and template is open.

Can I embed a calculator on my own site?

Yes. Every tool has an "Embed on your site" button that gives you an iframe snippet. The embedded version hides the site navigation and keeps the calculator, the formula and a small credit link.

Where do the formulas and benchmarks come from?

The formula is printed on each page so you can check it. Where a benchmark is used, the page names the source or states that it is the assumption the tool uses. We do not publish client results as benchmarks.

How often are new tools added?

Most weeks. The list is driven by what founders and marketers ask us for on calls, and by what people search for. If a tool you need is missing, tell us on the strategy call page.
