By supporting the bell (oron) with a single post, the sound resonates for a longer period of time, unlike conventional bowl-shaped orons. Tamayurarin, which has been patronized by many people since its launch in 2004, was born from the requests for a compact bell that produces good sound. Tamayurarin" was born from an unconventional idea that makes an orin upside down. After repeated challenges with the cooperation of local companies, a new bell (orin) with a swaying motion was completed. In 2005, we received the Good Design Award from Japan. Tamayurarin is used not only as a Buddhist altar, but also for meditation, yoga, relaxation.

Verdict
The clearest difference is in-app purchases: Tempra Ora at none against Zen Bell Timer's 3. Tempra Ora also leads on update cadence (every 2 days vs every 5 days). Zen Bell Timer's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 26.0). On price and ads there is nothing between them.
