KetoCypher: Keto Diet Tracker

Decode your diet. KetoCypher is a free keto and carnivore tracker that connects what you eat to how you actually feel, so you can stop guessing and find what works for your body. No ads, no data selling, and your log is encrypted on your phone.

FREE, NO PAYWALL ON TRACKING
• Logging, barcode scanning, fasting, health tracking, Health Connect, and on-device insights are free, with no ads.
• Optional Premium Backup adds automatic encrypted cloud backup and restore, so a new or lost phone never means lost progress. It is priced to cover its costs, nothing more.

Most trackers stop at calories and macros. KetoCypher pairs your meals with your weight, sleep, energy, mood, heart rate, glucose, and ketones, then surfaces the patterns hiding in your own data.

BUILT FOR YOUR WAY OF EATING
Pick a starting protocol and adjust it anytime: Carnivore (0 g carbs), Ketovore (10 g), Strict Keto (20 g), Keto (50 g), Low Carb (100 g), or fully custom. A built-in calculator estimates your daily calories from your body metrics, activity level, and goal.

LOG FAST, LOG ACCURATELY
• Log meals in seconds: carbs, protein, fat, and electrolytes
• Track total (or net) carbs with a clear daily view
• Scan barcodes or search a large open food database
• Fix any nutrition value that looks wrong, or revert to the original
• Remembers the amount you usually eat
• Custom foods, recipes, reusable meal templates, and favorites
• Plan meals ahead; planned food stays out of your totals until you eat it
• Intermittent fasting timers and eating windows

TRACK WHAT KETO ACTUALLY NEEDS
• Ketones from urine strips, blood BHB, or breath, plus your glucose ketone index (GKI)
• Glucose, A1c, blood pressure, and a full cholesterol panel (total, LDL, HDL, triglycerides)
• Sodium, potassium, and magnesium as first-class numbers, not buried micronutrients
• One-tap water quick-add
• Use the units your meter or lab uses, like mg/dL or mmol/L

CONNECT FOOD TO FEELING
• Health Connect: read weight, sleep, heart rate, glucose, and steps, and, if you choose, write your logged data back for your other apps
• A Today screen with the health tiles you choose, in the order you want
• Insights, trend charts, and weekly reports, computed privately on your device
• See how a meal, a fast, or a carb spike tracks with how you slept and felt

WHO IT'S FOR
Anyone eating keto, carnivore, ketovore, low carb, or LCHF, including people pairing it with intermittent fasting, who wants clear numbers without handing their health data to an ad network.

PRIVATE BY DESIGN
Your health data is yours. KetoCypher encrypts your food log, biometrics, and notes on your phone before anything leaves it, with strong end-to-end encryption.
• The server stores ciphertext only. We cannot read your entries.
• No admin key, no backdoor.
• Free encrypted backup files you can save anywhere, locked with your own passphrase
• A 12-word recovery phrase keeps you in control of your account
• No ads, no data selling, no tracking networks.

MADE BY A SMALL, INDEPENDENT STUDIO
KetoCypher is built by Optikal, an independent studio in Colorado. We read every piece of feedback you send from the app.
