Questions, answered.
Are the tools really free?+
Yes. No sign-up, no email gate. Every tool runs in your browser, so the numbers and files you enter never reach our servers.
Where do the benchmarks come from?+
Where a tool shows a benchmark, it names a public source and the date we checked it. Everything else is labelled a rule of thumb. None of it is Fovea customer data.
Is the Meta specs data current?+
The specs were read from Meta's Ads Guide on 2026-10-21, and every placement links to Meta's own page. Meta changes them, so check before a big launch.
Which tool should I start with?+
The break-even ROAS calculator. Every other number, from a creative test budget to a winning ROAS, means more once you know the line you have to clear.
What does Fovea do that the tools do not?+
The tools work on numbers you type in. Fovea syncs your Meta ads every night and keeps spend, ROAS, hook and hold next to every creative you link, in one AI-tagged library linked to your Shopify products.
The math is easy.
Which ad won?
Fovea links every creative to its Meta spend and the Shopify product it sells, so the numbers are already done on Monday.
