Elementium is ready for iOS 18 and iPadOS 18. If you’ve updated your device you’ll be able to take advantage of all new dark mode and tinted icons as well as new Control Center widgets. DARK MODE & TINTED APP ICONS I’ve updated all of Elementium’s icons to support iOS 18’s dark mode and Home Screen tinting (in addition to the existing light mode icons). You can preview how Elementium’s new app icons will look from Settings > App Icons. ION subscribers also get access to dark mode and tinted variants for all the premium app icons. CONTROL CENTER WIDGETS You can now jump into the Periodic Table quicker than ever using the new Control Center widgets available with Elementium on iOS 18 and iPadOS 18. There are three new widgets available to let you quickly jump into the Periodic Table, Periodic List, and the Solubility Calculator. Add them to Control Center and your next study session is only a tap away. As always, stay tuned for more new features and content soon — I have a lot of big updates coming shortly! And, if you like Elementium, please take a moment to leave a review on the App Store. - Sam

Hello! It’s been a while since the last Elementium update. I've been working on exciting new features and look forward to sharing them soon. For now, this update includes performance tweaks and a few bug fixes. This update fixes an issue where widgets on iOS 17 and iPadOS 17 had excessive padding around their borders. This is also the first update requiring a minimum of iOS 16 and iPadOS 16. Please update your device if you haven't yet! Stay tuned for more new features soon! If you like Elementium, please leave a review on the App Store. - Sam

Hi there! This update to Elementium includes a few bug fixes and improvements. Many of you have been asking for the ability to change units of measure without the need for a subscription. You can now do this. Units of measure are now included as part of the one-time purchase for "Advanced Tools". Of course, if you're an ION subscriber, you'll still get all the same great benefits. Those of you who use Elementium on iPad with iPadOS 15 or iPadOS 16 will also notice a number of small improvements and fixes for some cosmetic bugs. As always, stay tuned for more new features and content soon! And, if you like Elementium, please take a moment to leave a review on the App Store. - Sam

Hey, thanks for updating Elementium! This update includes three new app icons: "Jack o Lantern", "PRIDE 23", and "Transgender Pride". Plus you'll find improvements to sharing and deep links. I've also fixed an issue where sidebar selections were not respected on iPad (sorry about that!). More to come soon! Cheers, Sam

The "Density, Data and Charts" Update Thanks for using Elementium! This update includes periodic trend charts, improved element data, density measurements, and reduced download size. And, unfortunately, this is the last update that will support iOS 15. If you're still running iOS 15, now is the time to update your device. This update also fixes a crash some folks were experiencing on iOS 16. DENSITY & DATA This update includes a vast swath of improvements to element data. Most notably, elements now have density data. Density information is displayed for each element (where available) in grams per cubic centimeter. ION subscribers can also sort and filter elements by density. Density data is sourced from the National Institutes of Health PubChem database. You'll also notice a number of improvements to other data points including atomic mass, electron configuration, and discovery year. CHARTS ION subscribers can visualize the active periodic trend with interactive charts*. Choose from electronegativity, density, or atomic radius and then tap the new chart button at the bottom of the periodic table. These interactive charts make it easy to visualize trends across the elements. REPORTING INACCURACIES If you come across incorrect data, you can now report it so it gets fixed in a future update. To report data inaccuracies, tap the "..." button on an element, and then tap "Report Bad Data". UNIT TOGGLING ION subscribers can now change temperature and length units directly while viewing an element. Just tap on an element's boiling point, melting point, or radius to cycle through the available units (e.g. to change from Kelvin to Celsius). SMALL TWEAKS & IMPROVEMENTS Atomic mass, when shown in the periodic table, now responds dynamically to the size of the table. For example, at its largest size you should see up to 5 decimal places. At the smallest size, where mass is still shown, you'll only see 2 decimal places at most. And, in my ongoing efforts to improve accessibility throughout the app, dark mode colors are more legible. STORAGE SIZE The amount of space Elementium takes up on your device should now be around 33% less than the previous version (that's approximately 60 megabytes!). Huzzah for more space and less data use! As always, thank you so much for your support. Your votes on the roadmap are both encouraging and helpful, and I'll be working on the most popular requests for the next update. If you're enjoying Elementium please take a moment to leave a review -- it really helps :). Cheers, Sam *Requires iOS 16.0 or higher.

Hello! I'm excited to share "The Fuzzy Roadmap" update with you all. From the in-app settings you'll find two new items: fuzzy search and roadmap. ROADMAP You can now view and cast your vote for planned and upcoming features. Open the in-app settings and choose the "Vote on New Features" option. Here you'll find a list of planned and upcoming features. Tap the up-arrow to cast your vote for the the features you'd like to see implemented the most. I can't wait to see what ideas you're excited about; and remember to check back regularly to see the status of any planned updates. FUZZY SEARCH I've begun rewriting the element search algorithm from the ground-up using a new "fuzzy" search technique. This means search results for elements will be a lot more forgiving. For example, searching "Neptune" will show "Neptunium" and searching "Bo" will only show "Boron" and "Bohrium" (instead of every element that has the letters "b" and "o"). The results are much more accurate, more forgiving, and just as fast as before. Because this is such a large change to how search works, you'll need to explicitly opt-in to try it out. I'd love to hear what you think and how it works for you! I have quite a bit more planned for the coming weeks and months; so stay tuned (and check the new roadmap)! :) Let me know what you think by leaving a review or sending an email to me at hello[at]samspencer.art. Cheers, Sam

Hello chemists! This update includes subtle, but exciting, improvements to the look and feel of element detail screens. You'll also notice a number of performance improvements and bug fixes :). Read on to find out more! ELEMENT DETAIL LAYOUT Element descriptions are now much, much easier to read. The color of an element only affects the top portion of the screen, so you can read without straining your eyes (on a higher contrast background). Additional improvements and hints have been added to element info items for customers who use VoiceOver. I've also added a sticky header to element detail screens so you always have quick access to additional element sources, and to close out of your current element. IMPROVED EXPORTING Exporting element data is now easier than ever. If you've purchased the "Export" feature, or are an ION subscriber, you'll now see a Share button (upwards arrow in a box) on each element detail screen. Tap on the share button to select the pieces of data you'd like to export. A new "Export all data" option also lets you share all information about an element in one tap of a button. And, of course, you can still export data as before by tapping and holding on a data point.  I want to give a big thank you to Alan for taking the time to provide feedback and insight into the export feature! CUSTOM TYPOGRAPHY (FONTS) ION subscribers can now customize the font style (serif, sans-serif, rounded), weight (light, medium, regular, bold), and line spacing to make reading about elements just that much nicer. Find the new options in Settings > Typography. PERFORMANCE IMPROVEMENTS You may have noticed unusually long wait times to get the Periodic Table loaded in recent updates. We're talking upwards of 2 (TWO!) seconds. That's a long time to wait around for the Periodic Table. Rest assured, this update reduces your wait time to about 30 milliseconds on most modern devices. SMALLER THINGS TO NOTE • Home Screen widgets now open to their displayed element • Filters & sorting should be more responsive • Fixed a few iPad layout issues As always, I want to give a big thank you to everyone who uses Elementium! I appreciate all of your reviews and feedback and read it all (and it often makes my day). So if you're enjoying Elementium, please take a moment to leave a review. If you have any feedback, or just want to say hey, send me an email at hello[at]samspencer.art

Hi there! I've been hard at work on a few wonderful improvements to Elementium these past few months. This update focuses on accessibility, performance, and in-app purchases. And, Elementium is now updated for Apple TV - perfect for projection in your classroom, or on a monitor in your lab. ION TRIALS Beginning in this update you'll be able to start a free trial of ION before deciding to subscribe. If you're on the fence about whether some of the features and tools included in ION will be helpful to you, starting a free-trial is a risk-free way to finalize your decision. And, as always, if subscriptions just aren't your cup of tea you can purchase individual features for a single, lifetime price. PERFORMANCE Performance improvements are hard to qualify, but here's what I think you'll notice: • Decreased download size • Faster app launch time • More reliable Spotlight results • Reduced battery consumption when viewing Bohr Models ACCESSIBILITY If you use VoiceOver or a screen reader, you'll notice that both the Periodic Table and element details are now much easier to navigate. Periodic elements are now a single VoiceOver item instead of disparate items. I am continuing to work on making Elementium more accessible and would love to hear any feedback; especially about what could be improved. DEEP LINKING This one is for all the power-users out there. You can now configure links to open specific elements using the elementium://element-name format. For example, to open the Nitrogen page, you'd use elementium://nitrogen. Improved support for Siri and Shortcuts is on the way; this should help out in the mean time, though! 3.1.1 BUG FIXES Fixes a number of small issues, including: • Purchasing a subscription should now immediately unlock all app content (no opening / closing required).  • Links to feedback and support are fixed.  • Resolved a crash that may have occurred on devices running iOS 15 when viewing photos for elements. I appreciate all of your love and support, and have so much more planned for Elementium over the weeks and months to come. If you enjoy the app, or find it helpful in some way, please take a moment to leave a review. And, if you're an educator or school administrator, I'd love to hear from you about how you use Elementium with your curriculum. With love, Sam

Hi there! This is just a small update to fix a few issues. That is all. More exciting things coming soon.

3.0.1 fixes an issue for some iPad users who may have seen a black screen when opening Elementium for the first time after updating. This should be fixed now: no more dark voids! Huzzah! And, if you missed what's new in 3.0, here's the run down again: RESIZABLE PERIODIC TABLE Just pinch to zoom in or out on the Periodic Table. As you zoom in or out, information will be added or removed to fit the available space (nice!). Plus, the Periodic Table layout is much cleaner and easier to read on any device. VISUALIZE PERIODIC TRENDS In addition to existing visualizations for classification, state, and orbitals you can now view trends for electronegativity and atomic radius. And, more will be added soon. ION subscribers get instant access to these new trend visualizations. SOLUBILITY CHARTS & CHECKER Check the solubility of different salts using the new solubility table, which shows a wide range of common solubilities at STP. ION subscribers get instant access to a new solubility checker to quickly check the solubility of two compounds without needing to use the lookup table. IMPROVED SEARCH Searching for elements is faster and cleaner, and when searching on the Periodic Table you'll still see elements that don't match (they'll just be dimmed instead of hidden). CONTINUED UPDATES I've still got a lot of updates and new features planned and can't wait to share it all with you. I rewrote a lot of the code in this version, so substantial updates should come faster from here on out. As always, if you have any feedback, questions, comments, or concerns please reach out to me at hello@samspencer.art or using the feedback option inside the app. And, if you have a second, please rate or review Elementium on the App Store or share it with one of your classmates or teachers!

Hi everybody! This little update introduces App Clips, so you can share the periodic table with your friends quickly in iMessage. Just long press on the Elementium app icon and select "Share App". Much bigger, more exciting, electrifying updates coming in the very near future.

This update makes some minor improvements to visual content and includes bug fixes.

Fixed issues with filtering and displaying content on an iPad, and when using a Traditional Layout.

Elementium is proud to be a part of the Indie Sticker Pack! Learn more in the app after updating, or visit indiestickerpack.com. Fixed issues with ION purchase pricing and Home Screen icons. Prices for ION features should be correct for your App Store now. iPad users now have access to custom Home Screen icons, and it's easier to select a new icon for everyone.

Bug fixes as well as a more cohesive look and feel.

Fixed an issue where the Today Widget was unable to load any data. It turns out this feature is actually really popular -- I had no idea. If you ever have an idea, feedback, an issue, or just a question please don't hesitate to reach out (tap "Send Feedback" from the "Guide" tab).

Improved localization for a number of languages. And for the first time, Chinese and Brazilian Portuguese localizations.

Rubbish! The Periodic Table in a list? But, why? Its something that's been requested for a long time -- a fan favourite, if you will. The new list of elements will help you to get to the information you need even quicker than before. Plus, ION subscribers now have access to Advanced Sorting Tools: a great new way to understand the elements. The new Advanced Sorting Tools allow you to sort by a number of properties including electronegativity, atomic radius, melting and boiling point and more. As always, this update includes bug fixes and some nice improvements. See if you can spot any new animations! Thank you for your support.

New content for ION subscribers and for anyone who has purchased the Visual Content Pack! Hydrogen, Helium, Carbon, and Nitrogen now have 3D planetary models you can view in Augmented Reality. These models are useful for illustrating additional natural (and cosmic!) occurrences of those elements. I'm looking forward to sharing more new content and some nice changes in a larger February update.

A winter surprise! Open the Info panel to change your app icon from the regular Elementium pink to a new Winter purple. Bigger updates coming soon.

Fixed bugs for the Today Widget and with visual content for Copper and Nickel.
