Making weight is not a diet. It is a deadline.
Put in your class and your date, and camp comes back as a timeline.
A CUT ENGINE THAT WILL SAY NO
Built backwards from the weigh-in through as many as five phases, each week with a start weight, a target end weight, and separate training-day and rest-day calorie targets.
Then it holds the line.
• Every diet week is capped at a 750 kcal deficit, a hard clamp in the arithmetic, so the plan never asks for more than 1.5 lb (0.68 kg) a week of diet loss.
• The weekly rate is graded against your own bodyweight: safe to 1.5%, caution to 2%, unsafe above it.
• If your class cannot be reached even at that capped deficit, the plan comes back "impossible" and prints how far short it lands, rather than prescribing into it.
• Weeks whose target falls under the intake floor, 1,500 kcal for men and 1,200 for women, are flagged.
• An unsafe or impossible plan hides its week-by-week breakdown until you tap through the risk.
• It sizes the final water cut, 3% of bodyweight by default and adjustable to zero, then stops: that part needs a qualified professional next to you.
THE DAY
236 foods are built in and work with no signal. Water keeps the exact amount you log. Add entries to past days from any screen. More food on training days, less on rest days, weekly total unchanged.
THE SCALE AND THE TAPE
One weigh-in a day, in your unit, with the exact gap to your class. With three weigh-ins in the last 28 days it projects where you land on fight day. 14 tape sites, each with its protocol on screen. Body fat four ways: US Navy, three-site or seven-site calipers, or a figure you type in. Estimates, and the app says so.
THE REST OF CAMP
Weight-class tables for MMA, boxing, wrestling (UWW), judo (IJF), BJJ (IBJJF, with the gi) and powerlifting. Muay Thai and kickboxing ship none on purpose: no single consensus table exists.
A workout calendar with session types from your discipline. Your fight record with the class you competed at. A leaderboard for your gym. Fasting windows (16:8, 18:6, 20:4, OMAD, or your own) with a live clock and a 28-day streak grid.
65 generic supplements, each with a caution, and 177 branded products from 69 brands ranked on additives and dose. Switch on "drug-tested athlete" and it stops recommending pre-workout blends and thermogenic fat burners, the two entries flagged for contamination risk.

YOUR DATA, YOUR ACCOUNT, PRO
The free tracker needs no account: logs, weigh-ins, sessions, fasts and measurements live on your phone. Create an account, or sign in with Apple or Google, only if you want a backup, a second device, or your gym.
Apple Health is optional. Fighter Cut reads weight, body fat, energy, steps, exercise minutes, resting heart rate, sleep and workouts. That stays on your phone unless you turn on Show this activity on the web in Profile: then daily totals of steps, calories burned, exercise minutes and workouts are uploaded to your account, only to show your activity on the web. Turn on sharing and it saves your weigh-ins, food calories and water to Apple Health. Never sold or used for ads.
Analytics run only if you opt in. No ad networks. One sponsored slot on the dashboard, labelled and dismissible. Export as JSON or CSV, or wipe everything from Settings.
Fighter Cut Pro adds the deeper plan and camp tools. There are no in-app purchases in this app: Pro is bought on fightercut.com, starts with a 14 day free trial, and shows up here on the same account. A Team gym code covers Pro at no charge to the fighter.
WHAT IT WILL NOT DO
No AI coach. No sauna, sweat-suit or water-loading protocol. It will not walk you through a water cut, and it will not tell you a bad cut is a good one.
Guidance only, not medical advice. Talk to a physician, a registered dietitian, or your commission before changing your diet, your supplements, or your weight-cut protocol.
