A current result screen from inside the app — captured directly from KetoLock.
Log the way that suits the moment — a photo of the plate, the barcode on the pack, or just say what you ate.

Point the camera at your food and KetoLock itemises the meal — each part verified separately, each portion correctable with a tap.

Type it or dictate it: “Two eggs, half an avocado, and coffee with cream.” KetoLock accounts for additions such as cream or sweetener instead of treating every cup of coffee the same.
The barcode reads the product label instead of estimating from a photo. Some trackers include barcode access free and others reserve it for Premium; KetoLock keeps it free with no daily cap. Normal anti-abuse safeguards apply.
No mockups, no renders — these are captures from KetoLock running, honest numbers included.
People explore ketogenic and low-carbohydrate eating for weight, metabolic health, steadier energy, and mental clarity. KetoLock helps make the food side easier to see and track — without promising that one eating pattern works for everyone.
Ketones provide the brain with an alternative fuel, and researchers continue to study their possible cognitive effects. Some people report steadier focus, but results vary and the evidence does not support promising sharper thinking for everyone. KetoLock helps busy students keep meal choices aligned with their plan without adding another complicated task.
The American Diabetes Association recognizes low- and very-low-carbohydrate eating as options that may help some adults with A1C, weight, blood pressure, triglycerides, or HDL cholesterol. Diabetes care is individual: major carbohydrate or fasting changes should be planned with a qualified clinician, especially when medication is involved.
Lower-carbohydrate eating may help some people manage appetite and weight. Outcomes depend on food quality, health, medication, sleep, activity, and whether the approach is sustainable — KetoLock records choices, not guarantees results.
Optional glucose, ketone, weight, activity, hydration, and fasting records can sit alongside the food log. That makes trends easier to review while keeping estimates, correlations, and medical conclusions clearly separate.
No KetoLock account is required. Health information remains on the iPhone, and Apple Health access is optional and controlled through Apple’s permission settings.
KetoLock is a wellness and food-tracking app, not a medical device. It does not diagnose, treat, or prevent any condition. If you have diabetes, take glucose-lowering medication, are pregnant, or manage another health condition, consult a qualified clinician before making significant dietary or fasting changes.
