Aada is the Finnish form of Ada, from a Germanic root meaning noble. It is gentle, clean and dignified.
It reads soft and fine, nobility made warm.
Aada does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Aada reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
