Best Progress Photo Apps for iPhone (Before and After)

The best progress photo app for iPhone is the one that does what your camera roll can't: put two photos taken weeks apart on top of each other so you can actually see the change. Flip between two shots a month apart and they rarely look different. Put the same pair under a slider, lined up on the same outline, and the change in your waist or shoulders often becomes obvious.

We make Periscope, a free weight tracker for iPhone with progress photos, and it's one of the apps compared here. Every app was researched from its App Store listing and official site or privacy policy in October 2026. We haven't used each app for weeks, so anything a listing or policy doesn't cover is marked "Not stated". Prices are US App Store prices as of October 2026 and change often.

How we compared

Four things, in order of importance:

1. Comparison tools. Side by side, a slider (one photo wiping across the other), an overlay or an animation. A slider is the most useful for spotting small changes because your eye stays in one place.
2. Alignment help. A guide on the camera screen while you shoot, or a way to line photos up afterwards. Without one, a slightly different distance can hide a month of change.
3. Where photos are stored. Body photos are about as personal as data gets.
4. Weight alongside the photos, and price, including what sits behind a paywall.

Some apps do photos as part of something bigger:

What are the best progress photo apps for iPhone?

Periscope: best free app with weight and a slider

Best for: weight tracking and before/after photos in one free app.

This one is ours, so factor that in. Each weigh-in can hold up to two photos, from the camera or your library. In the Progress tab you pick a Before and an After from any two entries, then drag a slider to reveal one over the other, or press Play to animate the change. The weight difference between the two entries is shown alongside. An Align Photo tool lets you drag and pinch each photo to fit a body outline, so shots taken from slightly different distances still line up.

Photos, weights and notes are stored on your iPhone, not our server, and an optional Face ID lock covers the app. The photos sit inside a full weight tracker: a smoothed trend line in weekly, monthly and yearly reports, widgets, a goal weight and Apple Health sync. It's free, with no ads, subscription or in-app purchases.

Where others beat it: there's no guide on the camera screen while you shoot (alignment happens afterwards), no timelapse or video, and no export of any kind. It needs Sign in with Apple, and it's iPhone only.

Fitness Trackr: most photo tools for a one-time price

Best for: people who want the most comparison options and will pay a few dollars once.

Fitness Trackr has the widest set of photo tools we found at a one-time price: pose guides while shooting, side-by-side and an interactive wipe slider (exportable as an animation), overlays showing days between photos and the change in weight and body fat, a timelapse, and auto-alignment in Pro. Weight and body-fat trend charts, a goal countdown and Apple Health import round it out. Its policy says there's no account, data stays on the device and it doesn't collect analytics.

It was released in July 2026 and has no US ratings yet, so there's little track record. Auto-align and MP4 timelapse need the $4.99 purchase after a 14-day trial.

Where it beats Periscope: camera guides, timelapse export, auto-alignment, a backup file and no account.

PhotoJourney: best camera overlay

Best for: matching your pose every time, if you don't need weight.

PhotoJourney is built around identical framing. Ghost Mode and camera guides (a thirds grid, selfie lines and body templates, with optional countdowns) help you repeat the same pose and distance. It also has side-by-side and swipe comparison, streaks and reminders, multiple "journeys", and HD timelapse and GIF export. It's rated 4.42 from 114 ratings.

The subscription adds unlimited journeys and photos plus HD export, and Apple lists Pro at several prices, with yearly plans from $34.99 to $44.99. There's no weight tracking or Apple Health. The listing doesn't say where photos are stored.

Progress Pics: Body Tracker: best AI alignment

Best for: people who want the app to line photos up for them.

This app aligns photos with AI pose detection, compares them side by side, links weight to each photo and builds timelapse videos. The listing says photos remain on your device and aren't uploaded, stored or shared. Its privacy policy names analytics and crash tools including Firebase Analytics, Crashlytics, Sentry and Mixpanel. Rated 4.59 from 46 ratings. Pro is $4.99 a month, $9.99 to $29.99 a year, or $39.99 lifetime.

WeightSnap: photos plus GLP-1 dosing

Best for: people on a GLP-1 or peptide protocol who also want before/after photos.

WeightSnap has shifted toward dose schedules and injection tracking, but its photo side is strong: before/after comparisons with stats, background removal, face blur, side-by-side video and a "Time Machine" slideshow, plus body measurements and a projected weight trendline. No account is needed. The listing says photos stay on your device unless you request an AI body-fat estimate. Rated 4.96 from 106 ratings. Premium is $7.99 a month, $34.99 a year or $69.99 lifetime.

CompareMyself: simplest free option

Best for: free photo comparison with nothing leaving the phone.

CompareMyself keeps it simple: log a photo and your weight (kg, lb or stone), compare two side by side, scroll a timeline and share collages. Its policy says photos are stored only on your device and never uploaded. It's free with no in-app purchases, but it was last updated in June 2025 and has no ratings yet.

Where it beats Periscope: no account mentioned, and stone as a unit.

Progress, MacroFactor, BitBody and MyFitnessPal: photos inside bigger apps

Progress compares any two of your front, side and back photos and keeps them on your device and in your own iCloud. Photos need Pro. Pick it if you also track tape measurements: it covers 17 plus custom ones.

MacroFactor has front, side and back photos with a side-by-side gallery and 21 body metrics. It's a calorie and macro coach first, with no free tier after the trial, so it only makes sense if you log food.

BitBody uses an AI pose assistant to take the photo, replaces the background, compares side by side and makes progress videos, with weight and BMI charts. The listing says measurements stay on your device and are locked by default.

MyFitnessPal lets you attach a photo to a weigh-in in the app, cropped square. We couldn't confirm a comparison view.

Can you just use the iPhone Photos app for progress photos?

Yes, and it costs nothing. Keep your shots in their own album, or hide them: Apple's support page says that from iOS 16 the Hidden album is locked by default and opens with Face ID or Touch ID, and hidden photos don't appear elsewhere in Photos, including the widget.

The trade-offs are real. There's no slider, overlay or alignment, so you're flipping between two images, and no weight attached. If iCloud Photos is on, the photos sync to iCloud, where they're only end-to-end encrypted with Advanced Data Protection turned on. That's fine for plenty of people; just make it a choice rather than a default.

Which progress photo app should you pick?

Our pick for most people is Periscope. It's the only free app here that puts a before/after slider, an alignment tool and a smoothed weight trend in one place, and photos stay on your iPhone.

If you want camera guides, a timelapse, export or no account, other apps do specific jobs better:

• Most photo tools for a one-time price: Fitness Trackr.
• Matching your pose while shooting: PhotoJourney.
• Alignment done for you: Progress Pics: Body Tracker or Fitness Trackr (Pro).
• Simple, free, no account: CompareMyself.
• Body measurements too: Progress.
• On a GLP-1 medication: WeightSnap.
• You log food: MacroFactor.
• You won't install anything: the Hidden album in Photos.

The app matters less than the setup: same spot, same light, same clothes, phone at the same height on a timer. Our guide to taking consistent progress photos walks through it, and how to track weight loss progress covers how photos fit with the scale and a tape measure. For the wider field of trackers, see the best weight tracking apps for iPhone; for data handling, our guide to private weight tracker apps.

Progress photos aren't for everyone. If they leave you picking yourself apart, or you have a history of disordered eating, skip them. The National Eating Disorders Association and Beat in the UK can help.
