Several iPhone apps can find your child in your camera roll. Kyn, Minis, ChildPix and Precious say their face matching runs on the phone. Apple Photos does the same for free in its People album, and Google Photos groups faces across iPhone, Android and the web. The apps differ most in what they do with the photos afterward.
We make Our Little World, a private baby book app for iPhone and iPad that does this too, so Our Little World appears in its own labelled block below and is not ranked. The list is ordered by use case. We read each app's App Store listing, pricing and help pages and recent App Store reviews on 15 Oct 2026.
What does "on the device" mean in this comparison?
On-device face matching means your phone turns each face into a set of numbers and compares them with the faces you confirmed, so your photos don't have to be uploaded to be sorted. Our post on how on-device face matching works explains it in more detail. If you're wondering whether Apple Photos already does this, how Our Little World works starts with that question. In the table below, "where matching runs" is what each company says on its listing or privacy page. Where a company doesn't say, we say so.

What are the free options?
Apple Photos and Google Photos are the free defaults, and for many families they are enough.
Apple Photos, the best free option on iPhone
Apple Photos recognizes faces with on-device analysis and groups them in the People & Pets album, according to Apple's Photos privacy page. Once you name your child, Apple Photos names them in the other photos and videos in your library, per Apple's iPhone guide. The People album works on your own library, so photos on the other parent's iPhone appear only once they are shared to you.
Google Photos, for Android and mixed families
Google Photos groups similar faces into face groups that you can name, per Google's help page, which says the feature isn't available in all regions or account types. Google's page doesn't say where matching runs. Google Photos keeps face models until you delete them or stop using Google Photos for more than two years, per Google's retention page. Every Google account includes up to 15 GB shared across Gmail, Drive and Photos, per Google's storage page, as of 15 Oct 2026. Google Photos works on iPhone, Android and the web. We compare it in more detail on our Google Photos alternative page.
Which apps turn the photos into something?
Kyn, Precious and Minis each find your child and then make something from the photos.
Kyn, for automatic slideshows
Kyn's listing says "All photo recognition happens on your device" and that photos aren't uploaded unless you choose. Kyn builds a private album and cinematic slideshows, with those features under Kyn Premium. Kyn's listing showed ten in-app purchase options from $3.99 a week to $199.99 a year as of 15 Oct 2026. Kyn is on iPhone, iPad and Android. See our Kyn alternative page.
Precious, for monthly milestone pictures
Precious organizes baby photos into monthly pictures, growth slideshows and a photo calendar, with frames and stickers. Precious's privacy policy says face data stays on your device by default and goes to its servers only if you explicitly consent to model training. Precious's listing says a free trial or purchase is required and gives the US price as $4.99 a week, as of 15 Oct 2026.
Minis, for sharing a daily timeline with family
Minis builds a day-by-day timeline from your camera roll that invited family can view, and a partner added as an editor gets their photos in too, per the Minis site. Minis's privacy policy says face recognition runs entirely on your device, and that the photos the app picks for each day, plus any you add, are uploaded to its servers. Minis's listing showed in-app purchases from $2.99 a month to $39.99 a year as of 15 Oct 2026, and Minis had 5 ratings.
Which apps just find and keep the photos?
ChildPix and Fotoback are tools for finding or backing up photos rather than baby books.
ChildPix, for finding every photo fast
ChildPix asks for a few reference photos and then shows every match, organized by child. ChildPix's listing says all face recognition runs on the iPhone's Neural Engine and no photo or face data is uploaded for matching. ChildPix Pro, at $9.99 a month or $79.99 a year as of 15 Oct 2026, scans your whole library rather than recent months and adds optional encrypted cloud backup.
Fotoback, for backup plus an age timeline
Fotoback says it backs up your library with end-to-end encryption, and it sorts baby photos by age with milestone tags. Fotoback's site says all photo analysis runs on your device and offers 5 GB free. Fotoback's listing showed 100 GB at $1.99 a month and a one-time Pro App at $24.99 as of 15 Oct 2026. Fotoback's listing describes detecting baby photos in general and doesn't say how it tells one child from another.
What about BabyLoop, TinyNest and Babyfolio?
BabyLoop's site describes on-device face matching and one memory a day, but we could not find BabyLoop on the US App Store on 15 Oct 2026, and its App Store button doesn't link to a listing.
TinyNest and Babyfolio are often named in this category, but their listings describe sorting the photos you upload by date and age, not scanning your camera roll for a face.
Where does Our Little World fit?
The app we make: Our Little World is a private baby book app for iPhone and iPad. Our Little World finds your child in the photos on your iPhone after you confirm their face from a few photos, and face matching runs on the iPhone.
After finding your child, Our Little World lays out their life month by month and lets you add Firsts, letters and voice notes. Two parents share one family space. Grandparents and family members you invite can view what's shared with them, never face data.
As of 15 Oct 2026, Family costs $7.99 a month or $69.99 a year for 4 accounts, and Family Plus costs $11.99 a month or $99.99 a year for 12, per our pricing page. There is no free plan, only a trial of 7 days on monthly or 14 days on yearly. There are no ads. Export covers everything you made, with or without a plan. Our Little World is the wrong choice for Android families, anyone who wants a printed book and anyone who needs a free plan.
How we compared
We read each app's US App Store listing, pricing, privacy and help pages and recent App Store reviews on 15 Oct 2026. "Where matching runs" is only what each company states. We did not test matching accuracy in any app, including ours. For apps that keep a baby book rather than only finding photos, see our best baby book apps for iPhone.
