Capi vs Replapse

Capi helps you discover how your daily habits and health events relate to your sleep. Track the factors you want to test, import sleep data from Apple Health, and review clear statistical insights built from your own history. Log the details that matter to you - Track routines, workouts, caffeine, alcohol, supplements, screen time, stress, travel, naps, and other daily factors. - Create custom event types as yes/no, numeric, or low/medium/high entries. - Edit past logs and archive factors you no longer want to track while keeping historical data intact. Use your Apple Health sleep data - Import sleep, activity, workout, mindful minutes, and medication records with your permission. - Choose a preferred sleep source when multiple devices or apps write sleep data. - Review nightly sleep summaries including total sleep, awake time, REM sleep, deep sleep, and a single-night Sleep Quality Score. Find patterns with statistics - See which factors are associated with changes in total sleep, deep sleep, REM sleep, awake time, or sleep quality. - Compare impact estimates, confidence levels, sample size, and charts for each result. - Learn how to interpret correlation, reliability, and limitations directly inside each insight. Private by design Capi runs on your device and is built for personal experimentation. Your logged events and Health data are processed locally, and Health data is not sent to a server for analysis. The optional iCloud backup stores only the events you log yourself in your personal iCloud — never your Health data. Unlimited Access unlocks unlimited custom event types, custom analysis date ranges, and data export for deeper personal review. It also includes iCloud backup, so your logged events survive reinstalling the app or moving to a new device. Capi is for wellness and self-experimentation only. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Replapse is a workout tracker built around how you actually train, not how an app thinks you should. You decide what to track. For every exercise you pick the metrics that matter to you, whether that is weight and reps, hold time, rest, resistance band, angle, or the leg position on a front lever. If a metric is not useful to you, it is not on the screen. The result is a log that fits your training instead of forcing your training to fit the log. Log a full session the way it really happens. Mark warmups separately from working sets. Add drop sets and supersets to any set. Build circuits and run them for as many rounds as you want. Put a warmup section before your main work. Save your own workout templates, or start from an empty one and add exercises as you go. It works for the gym and for calisthenics in the same place. Track barbell and dumbbell lifts, and bodyweight work like pull ups, dips, handstands and front levers, without switching apps. Recovery matters as much as the training itself, so Replapse also tracks HRV. Take a reading and watch the trend over time so you have a real sense of how rested you are before a hard session. You can log your bodyweight too, which means your strength, your recovery and your weight all sit in one profile instead of three separate apps. HRV readings are taken with a Bluetooth heart rate monitor, like a Polar H10, a Garmin or Wahoo strap, or any standard Bluetooth chest strap. Pair one, take a reading, and your recovery data sits next to the rest of your training. Everything stays on your device. No account, no sign up, no cloud. Your training is yours and it never leaves your phone. Create a profile in a few seconds and start logging straight away. If other people share your device, add a profile for each of them and keep everyone's history separate. Replapse is for people who want a complete picture of their training and the freedom to track it their own way. What you can do: Pick your own metrics for every exercise Log warmups, working sets, drop sets and supersets Build circuits with multiple rounds Create warmup sections and your own templates Track gym and calisthenics side by side Record HRV and follow your recovery over time Log bodyweight and watch it change Measure HRV with a Bluetooth heart rate monitor Keep multiple profiles on one device Use it fully offline with no account
