Fitness accountability for iPhone
Stay locked in with your people.
LockedIn pairs you with a training partner and your friends. Build pair streaks, make weekly pacts you actually keep, and let Spark keep you moving.
Free to download. LockedIn Pro subscription, details below. Requires iPhone.


Everything you do, and everyone who does it with you.
Train, fuel, recover and check in with your circle, all in one app.






What you get
Built so you show up.
Workouts and PRs
Log sets, reps and weight, see the muscles you trained on a body map, and keep your bench, squat and deadlift history in one place.
Nutrition that is easy
Set calorie and macro goals, log food and water, or describe a meal and get an AI estimate you can edit before anything is saved.
Partner pair streaks
Pick one training partner. Every day you both train extends your pair streak and earns bonus XP. See each other’s week at a glance.
Weekly pacts with stakes
Agree on how many days each of you will train for 1, 2 or 4 weeks and, if you like, a friendly stake: a coffee, lunch, carrying their gym bag. Miss it and you owe an IOU.
Lock in mode
Tap Lock in when you start training. Apps you pick are blocked with Screen Time, and your partner can see you are locked in now, only if you share it.
Friends, feed and Snaps
Share to your circle, post stories, send Snaps that open once, and see who is online with a green dot. You choose what to share and can turn online status off.

Spark, your coach
Spark is LockedIn’s blue-flame mascot and your optional AI coach. Turn it on for a daily breakdown of your training, food and body numbers, and ask Spark questions. Spark never shames and never replaces a doctor.
Accountability, step by step.
Choose your person
Invite a partner or friends with a link. One partner at a time, by mutual consent.
Make a pact
Each of you picks your own training days for the week. Add a stake if you want one. It is honor system only.
Lock in and show up
Tap Lock in, train, and watch your pair streak grow. Run it back when the week is done.
No money. Just friends keeping each other honest.
Stakes in LockedIn are a word two friends agree on. The app never handles payments between people, and nothing is guaranteed or enforced beyond a friendly IOU.

Questions
Do I need a training partner?
No. You can use LockedIn on your own or with friends and family. Choosing one partner unlocks pair streaks and weekly pacts, and you can change or remove your partner at any time in Settings.
Does LockedIn handle money for stakes?
Never. A stake is just a label two friends agree on, like “Coffee”. LockedIn does not move, hold or track money. If someone misses a commitment, the app records an IOU that the other person can mark settled or forgive.
What does it cost?
LockedIn is free to download. LockedIn Pro is a single auto-renewing annual subscription. New subscribers get a 7-day free trial, then US$44.99 per year in the United States (prices vary by country). Cancel anytime in your Apple ID settings (Settings › Apple Account › Subscriptions).
How do I cancel my free trial?
Open Settings › your name › Subscriptions › LockedIn on your iPhone and tap Cancel Subscription at least 24 hours before the trial ends, and you won’t be charged. The free trial is for new subscribers only; Apple decides who is eligible.
Who can see what I log?
Only you, until you choose to share. Sharing is off by default, goes to your friends unless you pick Public, and has separate switches per category. Nutrition sharing shows progress, never the individual foods.
Who can see that I am online?
Friends can see a green dot when you are in the app. You can turn that off in Settings › What friends see › Show when I’m online.
Is the body-fat scan or Spark medical advice?
No. Body-fat scans, food estimates and Spark’s coaching are AI-generated estimates for fitness tracking, not medical advice. Body-fat scans are only for adults 18 and over.
What devices does it run on?
LockedIn is an iPhone app. Download it from the App Store.
How old do I need to be?
You must be 13 or older. Body-fat scans require you to be 18 or older.
How do I delete my account?
In the app, go to Me › Settings › Delete account. It permanently removes your account and data. See Support for details.
