A very subjective star rating more less means:

• awesome-mac
• fontcase - font manager for iOS.
• Flyleaf - good looking read-it-later app (Freemium)
• ChatGPT - Official app from OpenAI. Doesn't need a key, just a free account. (Free)
• Anybox - best bookmark storage app (Sub: $15/yr, lifetime: $40)
• GoodLinks - quite good for the purpose (Paid: $5)
• Working Copy - as far as git on mobile goes - this is probably the best one can get. (Paid: $20)
• Web Inspector for iOS - web inspector for iOS Safari.
• Bear - note taking (Subscription: $30/year).
• Evernote Scannable - used to be the best, now it's not usable. Cannot save scanned images to photos.
• Adobe Scan: PDF & OCR Scanner - requires account! (Subscription: $10/m).
• iScanner - lots of functions, most of which, when clicked - popup a "Pro" screen, asking for money. Convoluted workflow (lots of taps required to scan and save to photos). Scans don’t look great. (Paid: $15)
• Tiny PDF Scanner - lots of functions, most of which, when clicked - popup a “Premium” screen, asking for money. Convoluted workflow (lots of taps required to scan and save to photos), scans don’t look great. (Paid $3)
• Meditation - the app doesn't look much, but has 1 great feature: you can use any mp3 with guided meditation or music and customize everything else and the app will sync your mindfulness minutes to the Apple's Health app. And it's free!
• Lichess - less bloated than the chess.com and has unlimited free puzzles.
• SongShift - transfer playlists between music services (Subscription, $20/y).
• Fantastical - probably the best calendar app for mac (Subscription ~€44/yr)
• Things - Best task manager (Paid: $10).
• Readwise Reader - A fantastic read-it-later app that in conjunction with the readwise service (syncing highlights between your reader, books, kindle and your pkn/notes apps) is unstoppable (Sub: $96/yr while in beta).
• Adguard - System-wide ad-blocker. It's expensive but occasionally gets discounted (even down to $14).
• xsearch - app that allows to set custom search providers in safari (Paid: €3.50).
• Weather - simple and free weather app with a nice widget.
• Maple Read - A good apple books alternative. Can use any custom font and reads epub & pdfs (SE version: €9).
• Scanner Pro - too many buttons and clicks, and useless functions, e.g. storing scans in iCloud requires pro, but syncing with iCloud doesn’t. Weird UI. Not a straightforward flow (e.g. saves docs to its own internal storage, and requres manually “exporting” them outside). Some basic functionality is free, but full featured app is not. (Paid: $30)
• Blank Spaces - Remove all distraction from your iPhone: provides blank widgets, dock-hiding wallpapers, and a simple widget with a textual list of the most important apps. (Subscription: €15/y, lifetime: €25).
• Prizmo - Currently seems to be the best iOS scanner app out there. Does everything Scannable used to do and more. (Paid €24)
• Reeder - The best RSS reader for Apple devices (Paid: $10).
