Free tools

Check your numbers before you spend more

Four free tools, each built from the checks we run in a paid audit. They take about a minute and need no call. Start with the one that sounds most like your week.

Predicted ROAS Calculator

When does your ad spend actually pay back?

Put in your CAC, day 1, 7 and 30 retention, and one real revenue-per-user number. It fits a curve to your own data and predicts your breakeven day and ROAS. No industry benchmarks.

Best for: Any app, game or subscription business with a few weeks of cohort data.

Find your breakeven day

Channel Profitability Audit

Which channel is quietly losing you money?

List each channel with its CAC and day 1, 7 and 30 retention. It scores every channel on CAC against LTV and tells you to scale, hold or pause it.

Best for: Teams spending on two or more channels.

Audit your channels

Growth Leak Check

Which part of your growth is actually leaking?

Five one-tap questions, about 30 seconds, no signup. How you make money, your day 30 retention, how many installs pay, how fast paid UA pays back and how you track it. It names the one most likely leak: retention, monetization, acquisition or measurement, and why.

Best for: Any app, game or subscription business that wants a first read on where the problem is, before opening a single dashboard.

Attribution Diagnostic

Do you actually know where your installs come from?

List the ad platforms and tracking tools you use. It scores how much of your traffic you can really see since Apple's privacy changes, and what to fix first.

Best for: Anyone scaling paid spend on iOS, or running Meta, Google and TikTok side by side.
