Alpha Progression vs Happy Scale

Alpha Progression is a strength-training app for Android and iOS that logs workouts and uses performance to recommend weights and repetitions. Its Pro plan can generate a training plan from goals, equipment, training frequency, and duration; users can adjust the exercises, sets, and reps. The library contains 795 exercises with instructional videos filmed by certified trainers. Progress tools include charts, personal records, streaks, achievements, and CSV export. Users can follow plans, log workouts, and get Pro progression recommendations offline, but creating a new plan or workout needs an internet connection. With consent, the app can exchange activity energy, weight, body-fat percentage, and exercise data through Apple HealthKit and Google Health Connect. The free plan includes personal plans and unlimited logging, but excludes plan generation, recommendations, charts, and advanced tools. Pro Monthly costs $12.99 a month; Pro Yearly costs $79.99 a year, with a 14-day trial for eligible new customers. Subscriptions auto-renew unless canceled before the billing cycle ends.

Happy Scale tracks weight trends by smoothing daily scale readings with moving averages, helping users distinguish progress from day-to-day fluctuation. It lets users divide a weight goal into smaller milestones and estimates future weights and the time to reach a target from current trends. The app can import and export weight entries through Apple Health when permission is granted; Apple Health is not available on iPad. Health data stays on the device by default, so a server login is not needed to record or retrieve it. Dropbox sync and backup are optional, and the app accesses only its own Happy Scale folder. Profiles can be passcode-protected. The maker says it will not share personal or health data without permission and that analytics exclude health data and personally identifiable information. Happy Scale is free with in-app upgrades. Deluxe costs $1.99 a month, $11.99 a year, or 39.99 USD once. It supports iPhone and iPad with iOS 16 or later, and Apple silicon Macs with macOS 14 or later.
