[Beta Testers Needed] PeakFit: The iOS App for Unified Fitness Data Tracking

clout Inc. (Headquarters: Minato-ku, Tokyo) is now accepting applications for 10 beta testers for "PeakFit," an iOS fitness logging app that consolidates training, nutrition, and body composition tracking into a single interface. Participation is free.

Those who use the app for 10 days and complete a follow-up survey will receive a 3,000 JPY reward.

About PeakFit

PeakFit is an iOS fitness logging app with the concept of "turning motivation into numbers." Traditionally, fitness tracking was fragmented—requiring separate apps for nutrition, workouts, and body measurements. PeakFit brings all three together.

By simply logging workouts and meals, the app automatically calculates daily calorie intake/expenditure and PFC (protein, fat, carbohydrate) balance. It is designed to visualize "current status" and "distance to goals" through numbers, guiding users on their next steps.

No account registration is required; data is stored locally on the device. The app is completely free, with no in-app purchases or subscriptions. It is currently being distributed via Apple's TestFlight.

Development Background

Development began from the representative's own experience. After 10 years of self-taught training without significant physical changes, shifting to "recording and managing nutrition and training through numbers" produced dramatic results.

However, at the time, necessary information was scattered across multiple services—nutrition calories, lifting weights, and body weight/fat percentage measurements were managed separately. Connecting these mentally was the biggest hurdle to long-term tracking.

"The more serious you are, the more you exhaust yourself by switching between apps. I wanted to create an app that consolidates everything and provides numbers on the next step." This vision led to the creation of PeakFit.

Representative Comment

"To improve, what's truly needed isn't grit—it's 'recording and visualizing through numbers.' Knowing exactly what's missing or how much you've exceeded the previous record significantly boosts training precision. PeakFit is a tool to redirect the efforts of hardworking individuals toward the 'right direction.' Through beta testing, we hope to gain candid feedback from those serious about training to polish the product further."

Competitive Advantage

Most apps are split into specific functions, forcing dedicated users to manage multiple apps. PeakFit resolves this fragmentation by treating nutrition, training, and body composition as data on the same scale.

Once consolidated, the relationship between "food consumed," "energy expended," and "body changes" becomes clear. Additionally, the app excels where international apps fail—providing support for Japanese convenience store foods and translating technical metrics into easy-to-understand terms, balancing ease of logging with actionable insights.
