Do you ever want a timer that repeats itself? Cyclic Timer keeps your screen light up and count down silently. When the timer reaches zero, it fires and repeats (upon your setting). The alert sound can be muted so it does not disturb your important work. This could be useful during workout, gaming, or any work that you do need to be notified in every certain time frame. *This is not a timer that supposed to run in the background.

Verdict
The clearest difference is in-app purchases: Cyclic Timer at none against Superdo's 4. Cyclic Timer also leads on rating (5.0 vs 4.6). Superdo's advantage is update cadence (every 3 weeks vs every 12 months) and ratings volume (22 vs 1). On price, ads, device support and iOS requirement there is nothing between them.
