Finch grows a bird. We grow you.

If you've used Finch, you already understand the idea behind ftns.ai. You've felt the thing that makes it work: a checklist asks you to be disciplined, but a small creature asks you to show up for something. That's a completely different feeling, and it is the reason Finch has north of ten million downloads and a 4.9-star average across hundreds of thousands of ratings.

We're not going to pretend that's an accident, or that we invented the care loop. Finch has done more to prove it than anyone. What we've done is change one variable: the character.

The one-sentence difference

In Finch, you take care of a bird. In ftns.ai, you take care of a full-colour 3D model of yourself — your digital twin.

That sounds like a small swap. In practice it changes the whole emotional contract. A bird is something you look after. A twin is something you are. When your bird droops, you feel like a slightly negligent pet owner. When your twin has had three flat weeks, you're looking at a consequence in your own shape.

Neither response is better in the abstract. They are better for different people, on different days, for different things.

What Finch is genuinely great at

We'd rather be useful than persuasive, so:

• Finch is the best gentle-entry self-care app available. Its whole design philosophy is shame-free, and it earns that. Onboarding hatches your bird before it shows you a single feature, so you are attached before you are asked to do anything.
• The free tier is unusually generous and ad-free. Finch's own community documentation is straightforward that the free version contains everything you actually need, and that there are no members-only items in the shop.
• The domain is mental wellbeing. Mood check-ins, breathing exercises, journaling, reflection prompts, small self-care goals. If that is what you are looking for, Finch does it better than we do, because it is what Finch is for.

Still here? Then you probably want the other thing.

What ftns.ai is for

ftns.ai is a fitness habit game. The domain is your body and your day: workouts, sleep, steps, water, meals, weight, mood, and a couple of things most apps ignore, like alcohol and caffeine. All of it feeds one number — your Life Score — and the Life Score drives what your twin looks like.

Three things follow from that.

• Your twin updates weekly, not daily. This is deliberate. If a single skipped session visibly changed your character, the model would be lying to you and you would stop believing it by week two. Bodies move on trends. So does your twin.
• Apple Health does the boring part. Steps, workouts and last night's sleep flow in on their own. The app works before you have logged anything by hand.
• Future Self. The part nothing else in the category has: your twin projected across six horizons and three timelines — Current Pace, On Plan and Coasting. It is free, unlimited, and it never costs gems.

More on how that loop is built in what a digital twin actually is and how the Life Score works.

The twin looks like you

Your twin is a full-colour 3D model built to your own proportions. It's you, in the game, and it changes as you do. That is a deliberate bet: the closer the character is to you, the harder it is to shrug off. A bird drooping is a pang. Your own twin looking flat after three quiet weeks is a different kind of information.

What it isn't is an assessment. ftns.ai is a game in the Health & Fitness category. It isn't a medical product. It doesn't diagnose anything, doesn't give clinical advice, and doesn't tell you what any of your numbers mean about your health — and a model that looks accurate still isn't measuring you.

Photos are optional either way. Your twin is built from your own metrics, and if you do add the posed shots during setup they are processed in memory only, never stored on our servers, and discarded the moment your twin is built. The full version of that answer is here.

Side by side

Finch pricing and features per finchcare.com and the App Store listing, checked 20 August 2026. Both products change; check before you buy.

On the money

Finch charges $9.99 a month, or $69.99 a year. We charge $4.99 a month, and Premium buys monthly cosmetic drops, a bonus gem stipend and a supporter badge only you can see — nothing that touches your score, your tracking, your weekly updates or your Future Self.

We're not claiming Finch is overpriced. They fund a free, ad-free product for millions of people, and their paying members are the reason it stays that way. We're pointing at a real difference in what the two subscriptions are for.

On privacy, we go further

Finch has friends features and an invite system that rewards you for bringing people in. That is a reasonable choice and plenty of users like it.

We don't have any of it. No social feed, no friends list, no leaderboards, no comparative ranking anywhere in the product — not at launch, not later. You get one shareable score card, and you export it yourself, to wherever you want, when you feel like it. The app never posts anything.

If you've ever quietly deleted a fitness app because your streak became something other people could see, that's the reason we built it this way. The longer argument is in why there is no social side.

So which one

• Use Finch if you want gentle mental-health self-care, you like the softness of caring for something outside yourself, and the point is mood, reflection and small daily kindnesses.
• Use ftns.ai if you want the same loop pointed at your body, you would rather the character be you, you want your steps and sleep to count without logging them by hand, and you want to see where your habits are heading.

Plenty of people run both. They're not the same app, and one of them has a bird.
