Love it! Well worth the investment!

I’ve been using this app KRON for a few months now and loving all the fun moments, so I strongly recommend it. Creative people and innovators who likes fresh ideas will get the most out of this app.
I imagine that app lovers like me will recognize it is rare to see the amount of care and thoughtfulness going into an app like this one. I truly wish more apps take this route of high performance and innovative design rather than the quick and easy approach like thousands of apps out there. I will always choose a well conceived and finely tuned product, and honestly, I think we need to encourage high quality apps as a iPhone community.
Love the whole bunch of new features like the beautifully displayed Wordles and customizable plasma display settings.
I see there is a new review this week; I disagree with the user saying the price of this app is too high, and I got motivated to give my support here. I value hard work and this app KRON clearly is a winner and it is well worth the $10 they ask for. I would even go further to say this app is literally at least 6+ well made apps in one; I feel smart buying it when I spotted it so I’m already getting my investment’s worth and then some. It makes me feel good supporting excellent work. Can’t wait to see what’s next in the upcoming new releases.

Hello Carson11fly, Your tremendous positivity and praise is rocket fuel for us! We work hard and enjoy building KRON with love - it always feel amazing to be appreciated. We look forward to hearing your thoughts on the new features and refinements in the newly released KRON Version 2.3. Best Wishes, Your KRON Team

Innovation supreme

To say that KRON is a transformative app is an understatement! Mind blowing how you can view time on a continuous arc from seconds to decades - I just can’t get over it. Totally out of the box. We have literally been viewing time in boxes on calendars and papers for centuries! Welcome to the Apple Apps Age! KRON is a bold and innovative app that has changed my perception of time. The calendar functionality is stunning- I particularly like how I can see my numerous calendars in one view. KRON feels like something much more than a calendar - like a time navigation device from the future. A great investment indeed.

Expected alot More, but it's just a cool graphic look

The app looks amazing visually. But unfortunately falls short. I downloaded it thinking I was going to get the trial version, but I wound to paying $9.99 for it and the Titan bundle. They’re almost basically the same thing. Unless I’m missing something it really just doesn’t rise to the occasion. Like I said visually it’s stunning. But it’s hard to look at a full month's view of the calendar. And like some of the other reviews stated it’s not necessary to have all these newsfeeds. I was expecting a stunning looking, visually intense calendar app to really excel at being a calendar. But unfortunately it doesn't. I hate to post a negative review but I spent money on this one so I have to tell you what I think of it.

Developer Response ,

Hello Almanist, Thank you for your decisiveness in recognizing KRON's qualities, in downloading the KRON & Titan App Bundle [Hearts], and in giving our innovative platform a spin. It is heart warming that you 'get' our emphasis on the visual aesthetics that we excel at [Hearts]. We are respectful of your initial experience share; indeed, we are invigorated by the upside of evolving KRON to meet your vision of both a "stunning looking, visually intense calendar app" and "to really excel at being a [fantastic] calendar" - the beauty of KRON's creative journey is that we welcome and react swiftly to our user's experience share and suggestions - KRON has been evolving at lightning speed to achieve the highest marks - we tend to go for high hanging fruits such as expanding the capabilities of KRON to not only display Calendars but also News Feeds, Photos & Videos, and Spotify Music Listening history - each of these are major undertakings with the aim to please users like you, to expand your capabilities, and to achieve the goal of KRON being the go-to and must-have Time Navigation device that we and many users envision together. A major challenge exists in all other calendar apps is a feature that KRON excels at - this is the display of multiple sources and simultaneous events - it was natural for KRON to expand to enabling the display of expanded data streams beyond calendars. We again send our gratitude that your helpful feedback highlights a philosophical angle that we've embarked on - from the beginning, we realize that that there are many "Calendar Apps" available for the iPhone community, and many of them are awesome Apps that offer specific "Calendar" functionalities made for the currently familiar calendar user community, the common concepts pertaining to the familiar box-like designs that resemble the paper calendars that hung on the wall traditionally - our goal at KRON is to avoid reinventing the wheel, we elected to offer a high performance, aesthetically stunning new perspective on events of our lives that is natural for the hand-held smart-phone interface; our research indicates that KRON is the only App that displays live events across a arc-shaped continuous timeline, resembling events orbiting in the night sky; KRON is also the only App that displays the rhythms of user's various data streams via the exclusive cloud-like plasma mode, and your team at KRON has meticulously created the "Mission Control" ("..." button) for your real-time customization of the plasma; we went far for users, respecting the value placed on precision and fine control. Circling back to your experience regarding TITAN (KRON's Satellite App), TITAN is designed strictly as a simplified version of KRON with only calendars enabled, therefore, the reduced pricing when TITAN is purchased separately. With TITAN, we continue along the same trajectories of visual aesthetics on designing the refreshing "vista" (background landscape) and designer-color palettes as unique offerings on TITAN. With both KRON and TITAN, users typically would place special calendar(s) (for example, work-related calendars) on TITAN and reserve the "orbitals" of KRON for the viewing of other (for example, personal) calendars, photos, news feeds, and music. This way, these various data streams are available for viewing in their respective spaces in KRON and in TITAN without having to reset the menu to load and reorder the "orbitals"; in brief, for App Bundle users like you, TITAN offers a new "vista" where special calendars will have a special space for quick recalls and in a visually stunning designer user interface. In the creative journey that we are embracing, we anticipate there will be times when new features we bring might not eclipse with our users' expectations, so we whole heartedly encourage precious user feedbacks like yours. This way, your team at KRON will continue to grow the investment ($) you have entrusted in KRON as we continue to zero in on refinements and advancements for you. As you might have already discovered in the new KRON Version 2.3 released earlier this week (15Feb2021), a number of new (again high hanging fruits type) features have been incorporated based on constructive user suggestions like yours. We sure look forward to continue engaging with you as you check out more creative and innovative offerings from your KRON team. We greatly appreciate your feedback, and we hope new iterations on newer KRON versions will improve your experience. Please email us at directly for a more expeditious exchange, so we can understand the specifics that will please you the most. Best Wishes, Your KRON Team
