## What is SuccessLog?

SuccessLog is a private progress photo diary for tracking changes in how you look — skin, hair, workouts, body shape and more.

Just take a photo from the same angle each day, and you'll be able to look back and see the change. Your photos are kept inside SuccessLog, separate from the iPhone Photos app.

KEY FEATURES
- Take progress photos with the built-in camera
- Organize by category (Hair, Face, Body…) and tag (Front, Right, Left…)
- Scroll from then to now, or scrub through your photos with the slider
- Turn your photos into a slideshow video
- Hide what you'd rather not show with stamps (heart, star, circle, square). The original photo stays as it is, and you can add or remove stamps anytime
- See your streak on the calendar. Add treatments and events, or import them from iOS Calendar
- Filter by category, tag and date
- Edit the date, category, tag and note of each photo
- Recording reminders
- Available in English, Japanese and Korean

SUCCESSLOG PRO
- No ads
- Overlay your last photo while shooting
- Grid lines and face outline guide
- Import photos from your photo library
- Export selected photos to an album in the Photos app
- Sampling: show one photo every 3 days, every week or every month
- Add and edit categories and tags, and set camera defaults

PRO is available as a monthly subscription or a one-time lifetime purchase. The monthly subscription is charged to your Apple Account and renews automatically unless canceled at least 24 hours before the end of the current period. You can cancel anytime in iPhone Settings.

Your photos and records are stored only on this iPhone and are never sent to our servers. Deleting the app also deletes the photos in it, so export any photos you want to keep.

SuccessLog is not a medical app and is not intended for diagnosis or for judging the effects of any treatment. It's a tool for recording photos and looking back on changes in your appearance.
