- Real food data first when you log in Forge
- Set up in one message
Setup
Set up in one message, not a long quiz
Most fitness apps start with page after page of questions. Forge asks in one chat: say who you are and what you want, check the profile it builds, pick your pace. You’re logging in about a minute.
1Say it
One message: age, height, weight, goal and how often you train.
2Check it
Forge fills in your profile and asks only for what’s missing. Fix anything with a tap.
3Pick a pace
Choose how fast to go, and Forge sets your daily calories.
Change any of it later in your profile.
How Forge works
Forge is an iPhone app for logging meals, workouts, weight, water and sleep in plain language. It turns what you type into a draft you confirm, keeps your history, and lets ChatGPT or Claude read it so they can answer questions about your own data.
One meal, start to finish.
1Type it
Write what you ate the way you would say it. Forge drafts the items and calories.
2Confirm it
Check the draft, then confirm, edit or discard. Nothing from the chat is logged until you confirm.
3See it
Your day updates straight away: calories in, burned, net and weight.
ChatGPT · Claude
Turn your AI into a coach that knows your numbers
Your totals show what happened. Your AI helps you see why.
Connect Forge to ChatGPT or Claude. Your assistant reads what you ate, how you trained and how your weight changed, and answers questions about it. It can also log for you: whatever it creates arrives in Forge as a draft you approve.
- Included in the plan
- Reads your meals, workouts, weight, water, sleep and goals
- Logs only as drafts. You approve them in Forge.
- Drafts use your assistant’s estimates. Check them before you approve.
- Ask in your own language
- “Check Forge: what’s left for today?”
- “What did I lift last time?”
- “Give me a weekly review”
- “Where do my extra calories come from?”
- “Am I eating enough protein?”
- “What should I change next week?”
Tip: start with “Check Forge” so your assistant reads your data instead of guessing.
More examples and how the connection works
You
It’s Day A. What did I lift last time?
Assistant, reading your Forge data
From Forge, your last Day A: lat pulldown 45 kg, 3 sets of 10. Leg press 70 kg, 3 sets of 12. Seated row 45 kg, 3 sets of 10. On the pulldown, stay at 45 kg until you get two more reps, then go up.
Examples of questions an assistant can answer from your Forge data. The answers come from ChatGPT or Claude, not from Forge, and are not medical advice.
Long chats forget. Forge doesn’t.
Chats get deleted, split up and misremembered. Forge keeps the record.
- Every approved entry is stored in Forge
- Food and training in one record, not two chats
- Start a new chat any time. Your data is still there.
- Switch between ChatGPT and Claude. Same history.
One app instead of two
Most people track food in one app and workouts in another. Forge does both, plus weight, water and sleep, so calories in and calories burned sit on the same screen.
- Meals
- Workouts
- Weight
- Water
- Sleep
What else it does
Built for the thirty seconds you actually have.
Photo, label and barcode
Snap the plate, the nutrition label or the barcode. Forge reads it and drafts the entry.
Food database first
Items are matched to USDA and curated food data where possible. When there is no match, Forge estimates and labels the item as an estimate.
Workouts in one line
“Ran 5k in 30 minutes” logs duration, distance and an estimate of calories burned.
Knows when you mean
“Yesterday I had pasta” and “at 2pm” are understood and dated for you.
Also: water and sleep logging, reminders, meal planning, metric or US units, light and dark mode.
Progress that adds up
Built from what you log. No spreadsheets.
Every set, every record
Weekly sessions, minutes and calories, with personal records picked up from your workouts.
Your averages, not just your last meal
Daily intake against your limit and average protein, carbs and fat.

Questions
An iPhone app that logs meals, workouts, weight, water and sleep from one chat box. You type, Forge drafts the entry, and you confirm it. Connect ChatGPT or Claude and they can read your data and answer questions about it.
About a minute. Instead of a long questionnaire, you write one message about yourself and your goal. Forge fills in your profile, asks only for anything missing, and you pick a pace. You can change any of it later in your profile.
AI can be wrong. Forge matches items to food databases where it can and marks the rest as estimates. You review every meal before it is saved, and every entry can be edited later. Weighed portions beat guesses.
Not yet. Forge is coming to iPhone first, and Android is planned. Choose Android when you join the waitlist and we will email you when it is ready.
At launch: $2.99 a month or $24.99 billed yearly, after a 7-day free trial. Billing is handled by Apple.
In Forge, go to Profile, then Connected assistants, and generate a link code. Give the code to your assistant: it works once, for 10 minutes. After that, what you tell your assistant arrives in Forge’s AI tab as a draft you approve. Disconnect any time on the same screen. It is included in the plan.
No. They arrive as drafts in Forge’s AI tab and count only after you approve them. Drafts use your assistant’s own estimates, so check the numbers and edit them if needed before you approve.
Your data is stored in the United States. Meal and workout text and photos are sent to OpenAI to be parsed. If you connect ChatGPT or Claude, what you say to them goes to OpenAI or Anthropic. The privacy policy lists every provider.
