Paceva is the triathlon and multisport analytics app for athletes who swim, bike and run. It brings swimming, cycling, running and walking sessions into one history and one combined training-load view, so you can understand fitness, fatigue and form across disciplines. NEW: ANALYSE YOUR TRAINING WITH AI Choose what to review (today's workout, your latest session against the previous one, this week or this month against the last) and the app turns your data into a professional prompt, in your language. One tap copies it and opens your AI assistant: just paste it into a new chat. ONE ATHLETE. ONE TRAINING PICTURE. A hard swim, an easy run and a long ride all affect the same body. Paceva analyses compatible workouts from Apple Health together instead of splitting your progress across separate sport apps. TRIATHLON AND MULTISPORT ANALYTICS • Swimming, cycling, running and walking in one timeline • Combined training load using TSS across disciplines • Fitness, fatigue and form trends with CTL, ATL and TSB • Weekly, monthly and yearly progress views • Personal training zones for each sport METRICS FOR EACH DISCIPLINE Review CSS and SWOLF for swimming, critical pace for running, and power and FTP for cycling. Use sport-specific detail without losing the overall multisport picture. YOUR DATA, YOUR CONTROL Paceva does not require an account. Health and workout data are analysed locally and remain on your device. Technical crash diagnostics may be sent to help improve reliability; screenshots and performance traces are disabled. Export your history whenever you need it. PREMIUM Paceva Premium unlocks the full experience with monthly, annual and lifetime options, starting with a 7-day free trial.
