Frequently Asked Questions (FAQ)
Q1: Does it support distances other than full marathon?
Yes, it supports half marathon (21.0975km), 30km, 20km, 10km, and custom distances (1.0-200.0km). You can use it for ultra marathons and other long-distance races.
Q2: What is the pace setting range?
You can set pace from 2:00/km to 60:00/km. It covers a wide range from beginner's slow pace to elite runner's fast pace.
Q3: What is the precision of custom distance?
Up to 4 decimal places (0.0001km). You can set precise distances like 21.0975km (half marathon).
Q4: I selected even pace but the last segment pace differs from others. Is this calculation correct?
Yes, it's calculated correctly. The app manages pace in integer seconds (seconds/km), so when the theoretical pace from dividing target time by distance includes decimals, rounding to integers creates errors that are adjusted in the final segment. This adjustment minimizes the difference from target time.
This adjustment also applies to negative split and positive split strategies.
Q5: Is there a limit to the number of plans I can save?
Limits vary by plan. Free plan allows 3 plans, Basic plan allows 10, and Pro plan allows 100. To save more than your limit, delete existing plans first.
Q6: Can I share my pace strategies with others?
Yes, you can share pace strategies via SNS (LINE, X, Facebook, etc.) or email using the share feature. Recipients can view the strategy from the shared link, and if they have version 1.2.0 or later installed, they can open it directly in the app. If the app is not installed or is version 1.1.0 or earlier, please download the latest version from the App Store.
Q7: I received a shared link. How can I view it?
