Rutendo is from the Shona rutendo — faith, belief, trust in God. Rutendo is one of the Shona feminine names — central to traditional Zimbabwean Christian + Indigenous Bantu heritage. The Shona rutendo is central to Zimbabwean Christian theology + the Shona Bible translation (Bhaibheri Dzvene, 1949) heritage.
Rutendo 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 Rutendo reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
