The terms, in plain words
Last updated November 15, 2026
- Moose is a workout log you text. It is not a coach and not a doctor.
- 7 days free, then $8 a month. One plan.
- Text "cancel" to end your plan. STOP only stops messages.
- Your log is yours. Ask for a copy or have it deleted.
What Moose is
Moose is a workout log in iMessage. You text or voice note your sets. Moose logs them, tracks your PRs and compares each lift with last time.
Moose is made by 4ff inc., a Delaware corporation based in San Francisco, CA. "We" below means 4ff. Using Moose means you agree to these terms.
Not a coach, not medical advice
Moose is a log first and a light training partner second. It can suggest a next weight from what you logged. That is a suggestion, not a program and not medical advice.
You decide what you lift. Check with a doctor before you start training or if something hurts. In an emergency, call 911.
Who can use it
- You need an iPhone with iMessage.
- You must be 13 or older.
- Use your own number. One account per number.
Texting Moose
- You text first. Moose never texts a number that hasn't texted it.
- Moose replies when you text. It may also check in, like asking if you're done for the day.
- Reply STOP to stop all messages.
- Reply HELP for help.
- Message and data rates may apply. Those come from your carrier, not from Moose.
Price and trial
- 7 days free. One trial per phone number.
- Then $8 a month. One plan.
- No card to start. On day 7 Moose texts you a link to pay.
- Payment runs through Stripe. Moose never sees your card number.
- Your plan renews each month until you cancel.
- If the price changes, we'll text you before your next bill.
Cancelling
Cancel any time. Text "cancel" and reply yes. Your plan stays on until the end of the month you paid for, and you aren't billed again.
STOP only stops messages. It doesn't end your plan.
We don't refund part of a month. If something went wrong, write to hello@textmoose.com.
If you don't pay
Moose stops logging new sets. Your log is kept, and you can still ask for a copy or have it deleted.
Your log
Your log is yours. We only use it to run Moose for you.
Ask for a copy or have it deleted at hello@textmoose.com. The privacy page says what we hold and who handles it.
What we ask of you
- Don't send anything illegal, or anything that isn't yours to send.
- Don't flood Moose with messages or try to break it.
- Don't resell Moose or run it for other people.
We can pause or close an account that does.
When Moose gets it wrong
Moose reads your messages with an AI model. It can mishear a voice note or log the wrong number. It reads every log back so you can catch it. Tell it and it fixes the set.
Moose can also go down. We offer it as is, with no promise that it's always on or always right.
What we're responsible for
As far as the law allows, 4ff isn't liable for injuries, lost data or other losses from using Moose. If we do owe you, the most is what you paid us in the last 12 months.
Changes
If these terms change in a way that matters, we'll text you before it takes effect. Keep using Moose after that and the new terms apply.
Law
These terms follow the laws of California.
