Minder

Minder turns your phone into a pair of eyes that watch you work. Prop your phone up, slide to focus, and get to it. The eyes stay with you: they blink, glance around, raise an eyebrow, look proud when you've been going a while, and get very suspicious if you pick your phone up mid-session. It's body doubling for people with ADHD, or anyone who works better when someone's watching. A black screen, two eyes, and a reason to keep going. FREE, AND BUILT TO BRING YOU BACK โข Slide to focus; a timer and gentle check-ins every 15, 25, 45 or 60 minutes โข A daily goal ring and a streak, with one Streak Shield every month for the day life gets in the way โข A monthly challenge to chase, with a trophy when you get there โข Tag each session (Work, Study, Read, Write, Create) and plan it: open-ended, 25, 50 or 90 minutes โข A 5-minute break when you finish, while the eyes doze off too โข A Lock Screen and Dynamic Island timer while you focus โข Widgets for the Home Screen, Lock Screen and StandBy; tap one to start focusing โข A Start focusing control for Control Center, the Lock Screen and the Action button (iOS 18) โข Brown noise to focus to, made on the phone โข Your week, and where the time went, by tag โข Siri and Shortcuts: "Start focusing in Minder" and "How long have I focused in Minder" MINDER PLUS (SUBSCRIPTION) Everything in Pro, plus, while you're subscribed: โข Every eye pack (Galaxy, Gilded, Toxic, Blood moon) and the rain and fireplace sounds โข The Eye of the Month: a new look every month, kept in your collection โข 3 Streak Shields and 5 poster credits added at the start of every month โข Insights: your best focus hours, average session, pick-ups an hour and the month as a calendar โข iCloud backup of your focus history, in your own iCloud account Minder Plus is $2.99 a month or $14.99 a year in the US (local prices vary), and the yearly plan starts with a 1-week free trial for new subscribers.

Check the result Preview your compressed PDF and see its file size, page count, and percentage reduction. Your original PDF stays unchanged, so you can review the compressed copy before using it. Save, share, and find it again Save the result to Files or send it through the share sheet. Saved results remain available in History for previewing, sharing, renaming, or deleting later. Process your PDFs locally Compression runs locally without uploading your documents to a processing server. No app account is required. Choose the access that fits your needs Free access includes advertising and two successful compressions per day. Cancelled or failed attempts and results without a meaningful size reduction do not use your allowance. Previewing, saving, and sharing an existing result remain available without using another compression. Optional Pro access removes advertising and the daily compression limit. The same compression quality options are available with free and Pro access. Before you compress Compression converts each page into an image within the output PDF. Visual quality may decrease, and text in the compressed copy will no longer be selectable or searchable. Some PDFs may not become smaller, and a specific output size is not guaranteed. PDF Compressor lets you use the app at no cost. However, premium access may be available as an optional in-app upgrade.

Verdict
The clearest difference is in-app purchases: PDF Compressor at none against Minder's 10. Minder's advantage is ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.
