- Nutrition AND training AND accountability under one coach. Welling is nutrition-only.
- Proactive outreach: your coach notices when you go quiet and reaches out. Welling is logging-first — you have to remember to open it.

Who should use which
Welling AI is the right call if you want a polished, focused calorie tracker with photo-based logging and you're happy living inside another app. Threwline is the right call if you want coaching, not just tracking — your coach lives in your text messages, handles training alongside nutrition, and reaches out when you go quiet. Welling has optimized for nutrition logging within an app; Threwline has optimized for the entire coaching relationship without one. The difference is bigger than it looks: tracking shows you data, coaching changes your behavior.
