Diagnostic Utilities

Free diagnostic tools.

Working calculators for the numbers behind mobile game and app growth: LTV, ROAS, eCPM, retention and more. They are tools for UA, monetization and analytics teams, not games disguised as calculators. 28 interactive calculators and templates covering monetisation, user acquisition, ad networks, product analytics and team workflows. Built to surface the numbers that matter — no sign-up, no paywalls.

These free, no-signup calculators are informed by operator experience diagnosing monetization and growth problems across a 575M+ download portfolio. Pick the one that matches the decision in front of you — a retention curve, a UA bid cap, a mediation waterfall — and run your own numbers through it.
