About

Paceva

Read full description

Paceva is the multisport tracker for people who do more than one thing. Swim, run, bike and walk sessions land in one training history, with one training load and one honest answer about whether you are getting fitter β€” privately, on your device. ONE ATHLETE, NOT FOUR APPS Most training apps assume you only do one sport. Paceva reads every workout you record with Apple Watch or iPhone through Apple Health and analyzes them together, because your body does not have a separate fatigue budget per discipline. WHAT YOU GET β€’ Swimming, running, cycling and walking in a single timeline β€’ Combined training load (TSS) across all sports, not one per app β€’ Fitness, fatigue and form balance (CTL/ATL/TSB) for the whole athlete β€’ Sport-specific detail: CSS and SWOLF for swims, Critical Pace for runs, power and FTP for rides β€’ Personalized zones per discipline β€’ Weekly, monthly and yearly progress charts β€’ Export your complete multisport history to CSV or JSON BUILT FOR MIXED TRAINING Triathletes managing three disciplines in one week, runners who cross-train on the bike, swimmers adding dryland volume, and anyone whose training simply refuses to fit in one category. KNOW WHAT THE WEEK ACTUALLY COST A hard swim, an easy run and a long ride are not comparable on their own. Paceva puts them on the same scale, so you can see whether the week was sustainable before your legs tell you. PRIVATE BY DESIGN Everything is analyzed on your iPhone. No account, no cloud, no ads, no data brokers. Delete the app and the data is gone. PREMIUM Paceva Premium unlocks the full experience with monthly and annual plans, starting with a free trial. Cancel anytime in your App Store settings. Privacy Policy: https://paceva.analyticszone.app/en/privacy/ Terms of Use: https://paceva.analyticszone.app/en/terms/
