Your food diary, in a conversation. Tell LeanFrame what you ate. Review the suggested calories and macros, then save them to your diary. Forgot a meal yesterday? Ask your coach to add it to the right day. CHAT, REVIEW, SAVE Ask to add a meal or correct a recent entry. LeanFrame shows the proposed changes before you apply them. Ask questions about your food log and nutrition targets. LOG A MEAL FROM A PHOTO Take a photo or choose one from your library. Review the estimated ingredients, portions, calories, protein, carbs and fat. Tell the scanner what needs changing before you save. Photo results are estimates, not exact measurements. PREFERENCES YOU CONTROL Ask your coach to remember a food preference. Review and confirm the proposed note before it is saved. Edit or clear these notes at any time. Chat history and saved notes stay on your device. Relevant context is sent to the AI service when you use the coach. YOUR USUAL MEALS Ask your coach to save a usual meal from entries already in your diary. LeanFrame keeps those recorded amounts. Ask to log the saved meal again on another day. YOUR DAY AT A GLANCE See today's calories, protein and meals. Open the diary for your full food log. Track weight and optional progress photos in Progress. AI body estimates are approximate and are not a medical measurement. FREE LOGGING, OPTIONAL PRO Manual food logging, the food database and nutrition targets are free.

Verdict
The clearest difference is in-app purchases: BMI Formula at none against LeanFrame's 2. LeanFrame's advantage is ads (none vs shown) and update cadence (every 2 months vs every 60 months). On price, device support and iOS requirement there is nothing between them.
