★4.6 (128.8K)Steffen Mayer
⚡This app is the direct market leader in the specific BMI-focused weight tracking niche, commanding a massive user base that dwarfs the target app.
Head to Head

The outtake for Weight loss tracker - BMI
Strengths to defend, gaps to attack
Core Strengths
- Privacy-focused 4-digit PIN protection secures sensitive health data
- Minimalist UI reduces cognitive load for daily logging
- Integrated photo-diary functionality supports personal progress documentation
Critical Frictions
- 30-day graph limit restricts long-term progress visualization
- Data-loss incidents post-update erode user trust
- Lack of ad-free monetization tier limits revenue
Growth Levers
- Implement cloud synchronization to prevent data loss
- Introduce premium ad-free subscription model
- Extend graph date ranges to support long-term retention
Market Threats
- Data-loss reports driving users to competitors
- AI-logging features in rival apps reducing manual entry utility
- Established clinical-grade competitors capturing health-conscious segments
What are the next best moves?
Ship cloud synchronization because data-loss reports are driving churn → stabilize retention
Multiple reports of historical data disappearing after the latest update
Trade-off: Pause the graph-range expansion sprint — data persistence is a higher-severity retention risk.
Introduce ad-free premium tier because users explicitly request it → increase revenue
Users state they would pay to remove ads to support development
Trade-off: Deprioritize the UI refresh — monetization path has higher immediate impact on sustainability.
A counter-intuitive read
The app's simplicity is its primary vulnerability; by avoiding clinical complexity, it fails to provide the long-term data utility that prevents users from switching to more comprehensive trackers.
Feature Gaps vs Competitors
- Cloud synchronization (available in Lose It! but missing here)
- Barcode scanning (available in Lose It! but missing here)
- AI-driven food recognition (available in Foodvisor but missing here)
Key Takeaways
The app excels at simple, private weight tracking, but the recent data-loss incidents and 30-day graph limit are driving users to more robust competitors, so the PM must prioritize data persistence and ad-free monetization to stop the churn.
Where Is It Heading?
Declining
The health-tracking market is consolidating around apps that provide long-term data persistence and AI-assisted logging. This app remains exposed due to its reliance on manual entry and the recent instability of its data storage, so the PM must address these reliability issues to prevent further user migration to more stable competitors.
Data-loss reports following the latest update cause significant frustration, which directly correlates to an increase in uninstalls.
The 30-day graph limitation prevents long-term users from seeing total progress, leading to dissatisfaction and eventual churn.
