Gregor
Read full descriptionHide full description
Minimalist calendar-based notes and journaling app. Guiding principles: # Simplicity You pick a day on the calendar and add a note to that day. Basic usage is as simple as that. No clutter, no distractions, no ads. # Reliability Your notes are stored as plain markdown files in iCloud or on your own device. Edit them with your preferred apps, copy or sync them wherever you want, and keep access and control regardless of Gregor itself. # Polish Access information easily, edit markdown from a native UI, and use local AI features to easily search and summarize your notes.
Margin
This app intelligently identifies and helps you remove unwanted files like duplicate photos, old screenshots, and large videos to free up storage space on your device. It allows you to preview exactly what will be deleted or compressed before making any changes, ensuring your important memories are safe.
- Groups near-identical photos
- Identifies screen recordings and expired screenshots
- Compresses large videos and images
- Previews space before deletion
- Runs entirely on-device
- Files recoverable from Recently Deleted

Your phone is full, and it's never the photos you meant to keep — it's five near-identical shots of the same moment, a screen recording from months ago, and the screenshot you took to remember something and never deleted. Margin finds all of it and shows you exactly what you'd get back before anything is touched. SEE THE SPACE BEFORE YOU FREE IT Margin groups near-identical photos into sets, picks the strongest frame in each one, and lets you review the rest at a glance — a full contact sheet per set, not one photo at a time. Screen recordings, expired screenshots (sorted by the text in them), and exact duplicate files are each their own category, so you know exactly where your storage is going. OR COMPRESS INSTEAD OF DELETE Long videos and large images over a size you choose can be re-encoded in place instead of removed — picked individually or as a batch, tracked from a compression tray. Camera, date and location metadata survive exactly as they were. NOTHING IS EVER PERMANENT Every deletion goes through your device's own Recently Deleted album — recoverable until you empty it yourself, exactly as if you'd deleted the photo in Photos. Nothing Margin suggests touches anything you've already favorited, edited, or filed into an album. RUNS ENTIRELY ON YOUR DEVICE Margin has no network code. There is no server, no account, no analytics, no third-party SDK — nothing your photos could be sent to, because there is no code path capable of sending them anywhere. Every comparison happens locally using Apple's own PhotoKit and Vision frameworks. Built for iPhone and iPad, sharing one engine with the Mac app.

Verdict
The clearest difference is update cadence: Margin at every 2 days against Gregor's every 4 days. Gregor's advantage is iOS requirement (18.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
