ftns. vs Stackd Health

ftns. is a fast, fully offline workout log built for people who just want to train. Type your workout in plain English and it instantly turns into clean sets with the right weight and reps. Add tags, muscle groups, and notes, then use the Insights tab to track progress over time with clear, granular views of your training. All features are completely free, and user data is completely stored on-device.

Stop guessing. Start knowing. Stackd brings your bloodwork, nutrition, workouts and supplements into one place, then shows you how they connect, with sources you can check yourself. UPLOAD YOUR LABS Snap a photo or upload a PDF of your blood test. Stackd reads the markers it supports, explains what each one means, shows where you sit against standard reference ranges and research-cited optimal ranges where available, and tracks your trends across every upload. Always check values against your report and review results with your doctor. INSIGHTS THAT CONNECT THE DOTS See how your labs, meals and training relate. Every insight links to its sources, such as the NIH and studies indexed in PubMed, so you can read the research behind it and bring better questions to your doctor. LOG FOOD IN SECONDS Search, scan a barcode, or describe a meal. Snap a photo of your plate or a screenshot of a recipe and get estimated per-serving calories, protein, carbs, fat and 25 micronutrients, with every ingredient editable.
