SecondsSprint makes it possible to determine the exact distance an athlete sprints given a fixed number of seconds. Sprint sessions where this app will be very useful: - 23” (men) or 27” (women) sprints, made popular by Chris Korfist and Tony Holler. - The Kosmin test, used to predict 800m and 1500m times. - Any other sprint or run with a fixed duration. HOW IT WORKS - Place cones at regular distances (e.g. 1 yard or 1 meter) in the zone where the athlete will finish. - Choose the number of seconds the athlete will sprint. 23 and 27 seconds are available by default, but any number of seconds can be entered. - Tap the big red START button as soon as the athlete starts to sprint. - Follow the athlete during the sprint and the video will freeze when time is up. - The frozen video will make it easy to determine the sprinted distance.

Verdict
The clearest difference is in-app purchases: SecondsSprint at none against Temporun calculator's 1. SecondsSprint also leads on ads (none vs shown). Temporun calculator's advantage is update cadence (every 3 weeks vs every 8 months) and iOS requirement (9.0 vs 16.6). On price and device support there is nothing between them.
