New features ready!

The iPhone has sparked a photo/video revolution. Never have so many people had continuous access to a camera. Never have so many people taken so many photos and videos. And never has it been so difficult to find a particular image, scrolling through row after row, grid after rigid grid.

CALLISTO by KRON uses KRONxARC technology to simplify navigation of your photos and videos, excelling at simultaneously visualizing "Arcs" of multiple albums across time. Instantly identify the time and cadence of when photos were taken and in what numbers. Quickly preview thumbnails to find the images you are looking for. Easily share photos with friends, family and on social media.

This new "Satellite" App from the KRON Suite of Apps is created for a specialized photo and video visualization experience.  

While our flagship app KRON offers access to a single photo album (Recents), CALLISTO offers an expanded capability to access all albums on your iPhone and iPad.

· Navigate and view thumbnails of your photos and videos quickly using simple, familiar gestures
· Assign separate "Arcs" to individual albums
· Review multiple photo albums simultaneously (Exclusive on CALLISTO)
· Quickly pan across time scales via the zoom-slider and short-cut buttons
· Reveal a holistic overview when zoomed out - a KRON App signature feature
· Open items in the detail pop-up mode and swipe horizontal to advance forward and back
· Interactive touch screen options to quickly:
· Tag a significant item to add a glow to find it again easily
· Open an item in the detail pop-up mode
· Center an item on the "Beam"
· Customize the color of an album "Arc" display
· Instantly access your camera from within CALLISTO (via the "+" button)
· See your collection organized daily in the "List" mode (via the arrow button)

What’s New

Version 3.1

1. The Preview Pop-up was originally set up to scroll between items in the "Beam" only; in this new version, an unlimited scrolling of the Pop-up offers access to all items in each album across the entire "Arc" of time. The movement of the "Beam", as visible at the top of the Preview Pop-up mode, is coordinated with the scrolling of items, creating a "time jump" sensation to improve orientation.
2. Live Photos are now previewed as short videos.
3. Menu layout - new option to show "ACTIVE" (the minimal design displaying only albums selected) or "ALL" photo albums (the original).

I've been waiting for this to drop; thank you!
You've done it again, so please don't stop anytime soon. All 3 apps are works of art.
— #CALLISTO is the beautiful complimentary cousin of #KRON, while wonderfully brilliant on its own merits and easily on par with #TITAN as well. 👍👍

If anyone is intrigued enough to still be reading this far you will probably regret not buying it sooner. — If only more devs gave as much of a š**t or were even half as innovative.

We are excited to share that there will be a new KRON version with cool new features coming very soon. We are also going to offer Apple Music Listening history on KRON and on LUNA (our 3rd Satellite App) launching very soon as well.

Thank you so much again for your powerful rocket fuel injection 💗💗💗
