Molecular Constructor

App used to better. Bring back the double tap to switch between drag and rotate. This 2 finger thing is inconvenient, your 2 fingers will either get closer or further away from each other and that will start zooming instead of sliding as you would want. It was much easier to visualise the molecule with the arrows and the rotation. Now you need to be extremely accurate in your movements in order not to make a mistake. Please bring back the simple things.

Wonderful !!! It works perfectly. It's a powerful app to create and learn 3D molecular structures. But, after reinstalling the app, all the previously created molecules inside the Android/data/com.alextepl.molconstr/files/ folder gets deleted. So please correct that bug. Edit: Thanks for the response, but if you save those files in the external storage, they won't get deleted after the app is uninstalled. Only files in the Android/data directory gets deleted.

Amazing! I hope in the future you can improve the render quality, especially that many phones today are very powerful and capable of rendering very complex objects, but im not complaining. One thing I do hope that is improved on, is the background, as staring at a single colour for a long time can cause eye strain. I look forward to the features you will add in the future!

I basically failed chemistry in highschool... I tried other molecule apps today, and this one is the winner. it takes a few minutes to get used to select, deselect, add bond, delete atom, but it is well worth it, especially for the shaping feature... I made a 5' adenosine monophosphate in about 2 minutes, and it looked really bad, but the shaping, pulled it together, and it looked like a textbook image... I was looking for Jmol mobile, and found something better! the ability to save molecules, and reload them is a winner. took less than an hour to make A,C,G,U and start making an RNA chain. awesome app. the zoom, pan, rotate controls are flawless, and I even made a short polypeptide with no performance issues... Chemists might find it lacking in features, but for the curious, and the learners, this app is priceless. 100!

Totally amazing. Just what I needed. Saves me so much time. Before this I used to spend hours on some mainstream 3D modelling app but this makes everything so much easier! I totally love it! {Also, a little bug: if I include '/' in the filename while saving, it says already exists! For example, if save a structure as "r/s q1" it says the file exists and whether to overwrite it. But when I do click overwrite, it does not save any file by that name.}

The app works well, although it is quite slow when adding bonds or atoms, but nothing too big. It should have more available elements and should have a different UI imo, more categorized and cleaner, as I perceive this being a little bit too full. The app works great for what it can do, it calculates structure quite fast, and only slightly freezes when altering the molecule. imo, the system for adding and removing bonds should be different, but it is good as it's now.

I really like this app, i think its very useful. One thing that I think really needs to be added is the ability to manually set the maximum fluctuation. Because it automatically switches, it tends to waste a lot of time on high max fluctuation settings that don't really do anything after the first cycle.

This app is by far the best app I have found for this purpose. It has a friendly user interface and is very versatile. One thing I would really appreciate is an expansion on the tools available. Such as a bond angle measurement tool or an enthalpy of formation calculator. Even if it was a paid for feature I would definitely pay for it if it was reasonably priced.

My new favorite app! I'm no chemist, but this app is definitely super fun, educational, and feeds my creative interests in the subject. It's "hands on" approach has really taught me a lot about organic chemistry. My only complaint is the lack of other elements and tools. Aside from the hydronate tool, I would love to have a tool for chlorination and fluorination.

Please add more tools to the palette. For instance, I can't delete structures that I may have accidentally or intentionally placed onto the canvas. Also, it would be nice you have a feature a.) that would guess the name of the compound and b.) allow exporting the structure to other commonly used and standardized formats.

Absolutely LOVE THIS APP! GUI is pleasing. Could use some tweeking. I'd like to be able to make selections and rotate from there. Instead of only being capable of moving around the whole thing at once. Also auto shaping large molecules takes foreverrrr. 🙏

Cool app. Editing and moving things could be easier, but for a free app it's very nice. Took me a while, but I built myself a bucky ball (C60)! Edit: new changes in version 1.5 are nice improvements. A great change would be to allow moving and rotating just one molecule when there are several.

Rather easy to use, but there is no way to rotate the molecules individually, nor around an independent axis. If you move one, you move two, all of which turn around a predefined axis. Not what I'm looking for. I need to be able to compare molecules. It's impossible with this app.

I like the concept a lot, as it provides estimated energy of the compound drawn. But the only thing missing, which might be very difficult to add, is consideration of resonance in compounds. Otherwise, excellent app with good handling features.

The only thing that shouldn't have been changed is the double tap to switch from rotation mode and transitional mode. The 2 finger gestures aren't easy to master whereas the older way of moving the molecules was simpler and more efficient.

This is a great app. It's really helpful for visual learners to see how the atoms interact and form shapes of molecules. I'd recommend adding folders to the library so the molecules you make can be organized.

Excellent app, it really helps to visualize molecules, automatically generates the correct structure and is easy to use. Definitely recommended for everyone who's interested in chemistry.

Amazing App! I didn't expect so much for an app with such a small size to be so functional. The appearance should be improved though. Only one missing feature: ablity to organize the library like creating folders.

Great game. A lot of fun when you have some free time. Very simpe controls, easy to understand. One thing I would suggest is adding elements like Uranium, Tungsten, ect. Nonetheless a very useful and fun app.

I had no idea I wanted an app like this until it showed up in my recommended feed. (I blame my obsessions with interhalogens and molecular word construction being observed by Google. All hail Big Brother!) (I haven't even opened the app for the first time yet and already know it's going to be fun. Not only is the design nice and clean, but the size is perfect for my phone that is strapped for memory.)

Amazing app. Has all the functionality of paid apps with less hassle for free. Only downside is the limited amount of atoms available. It really needs some heavier elements to work with.

Really great app, perfect for what I want, genuinely I can almost run computational calculations from my phone now. Great stuff. I was going to suggest getting better forcefields for giving me a planar nitrogen but then realised it was conjugated in the molecule I tested. Great stuff, thanks

I liked it especially because it's possible to change the molecular model(I.e ball & stick or space filling etc)-really helpful in appreciating certain aspects of molecular topology. One thing that's been bugging me however is that there's no PROVISION FOR MANIPULATING THE CHIRAL CENTRES in a molecule...would be really grateful if future versions address this issue.

So close! My only problem is that you can not easily unselect the atom. You need to make something random, undo it, and that seems to free it up. Still it's a hassle.

This is a good molecule structure maker. One can easily understand the shape of molecule by making molecule's structure. But, one thing could be better, that is to add more elements and binding limits of the specific elements as mentioned for them differently.

It's a very nice app to use; however, may I suggest the ability to add hydrogen bonds to be added? As well I would also like to suggest a 2D mode / a 3D lock where the molecule can't be rotated in a 3D fashion

Good app for visualisation but there is a bug that sometimes that atom chooser palate appeares and after that the app freezes which causes all the work done to be lost.. would be great if u could please fix this bug 👍

It's a great app. I wanted to model a thymine and i was really surprized to find that softwares like hyperchem could not make it properly. But i was able to make one on this app really easily. And it saves molecules with .mc formati so i have a question: how can we convert .mc fortmat to other formats. What does .mc format stand for?

Great, but It does not allow me to add links between several elements, for example, when reacting a hydroxide with a hydrogen sulfide to form a neutral halogen salt plus water, it does not allow me to link Sulfur with Calcium. In addition, only some elements of the periodic table are available in the app, they are not all.
