Make your Home Screen look the way you always wanted it to. DataFastView is a collection of twenty Home Screen widgets designed to look like they shipped with the phone β and to go transparent, so your wallpaper shows through every one of them. No subscriptions: the app is free, two widgets are free, and each page of widgets is a single purchase that is yours forever, on every iPhone signed in with your Apple Account. PICK A PAGE, MAKE IT YOURS β’ Status Portal β a large sci-fi control panel with the time, the weather, your month, your next events and reminders, and your battery. Two palettes. β’ Weather and time β today by the hour, the week ahead as soft curves, and a glass clock that looks like the Lock Screen's. β’ Calendar β the next events as cards, today's date, the whole month, and a large calendar with your events, reminders and the weather on one panel, by day and by night. β’ Productivity β ten shortcuts to your apps with their real icons, a four-tile version at icon size, and three world clocks that show whether it is day or night there. β’ Mail β unread messages from two accounts, on small or medium cards, in the colour you choose. Works with any IMAP account, Gmail included. β’ Health β this week's steps as a curve with today's count, and your average distance over the last 21 days. β’ Free β Storage and network, and the calendar list, for everyone. EVERY WIDGET CAN BE TRANSPARENT Each widget has a switch: draw its own background, or let your wallpaper through. Light and dark follow your phone. AND THE REST OF THE APP β’ Status β free space, link quality and a real speed test: download, upload, latency and jitter, with charts. β’ Dynamic Island and Lock Screen β fourteen live metrics, or a phrase of your own, in the colour you pick. β’ Control Center β your shortcuts one swipe away. β’ Track β your day on a map: where you stopped and for how long. Kept on your device for 90 days. β’ Passwords β a generator for strong passwords, ready to paste.

Mail passwords live in the Keychain and never leave the phone. In English and Spanish. Made for iPhone.

Verdict
The clearest difference is in-app purchases: Vocalize AI at none against DataFastView's 5. Vocalize AI also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.6). DataFastView's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). On price there is nothing between them.
