Explore the fascinating world of biological macromolecules: iMolview lets you browse and view in 3D protein and DNA structures from Protein Data Bank, drug molecules from DrugBank, and small molecules from Pubchem. Search for drug names like 'ibuprofen' or 'gefitinib' in DrugBank, or proteins like 'insulin' or 'thyroid receptor' in PDB. Information associated with each molecule in these databases is also at your fingertips. Sync and view your own structure files via iTunes. Molecular view can be customized with a rich set of molecular representations (wires, balls-and-sticks, space filling, ribbon diagrams, molecular surfaces) and various coloring schemes. Select residues, atoms or chains and color or change their representations individually. Select 'neighbors' of a ligand or any other selection to identify interacting atoms or residues. Set 'inertia' to the maximum and let your molecule spin in 3D indefinitely. Save the current scene (viewpoint + representation) as a slide which can be easily accessed later. Save the whole molecular document with multiple slides.

Super disappointing. ### 5/5 — Fantastic! Thank You! *2019-10-01, version 1.9.5* Visually stunning, better than apps on the PC or Mac. Perhaps someday it can calculate energies and maybe even a backend server option for number crunching? Works from iPad 2 to iPad Pro. Tim Cook must be mad. Efficient and artistic. ### 3/5 — Current version crashes *2019-02-07, version 1.9.4* Crashes on opening. Probably a temporary fault with an otherwise useful app. Hope it’s fixed soon ### 4/5 — 좋은데 좀 자주 튕기네요 *2018-10-14* electron density map 불러오면 로딩도 느리고 간단한 molecule 을 3D convert 해도 한 번씩은 꼭 튕김 ### 5/5 — fantastic *2018-01-30, version 1.9.3* amazing！I would like to give 100 dollar for this app. Just hope the developer would keep updating this app. Great! ### 4/5 — Huge Bonus *2014-04-30, version 1.8.4* Oh wow, they just added search for PubChem that suddenly let's me view small molecules, and with surface turned on with the electrostatic (or binding properties) view option, I can *see* an estimate of the real character of drug molecules. This is certainly the best visualizer out there for the iPhone. It's so far too slow to make surfaces for large proteins though, on an iPhone 5. Still, it quickly helps me better understand each week's biochemistry headlines since most reported studies already have sent their structural results to the Protein Data Bank. ### 4/5 — needs better depiction of electron density *2013-11-23, version 1.8.2* The dots style depiction is not very useful. please incorporate mesh surface like in coot. Thank you ### 4/5 — Keep it up *2012-08-28, version 1.5* Excellent app. Love the ability to superimpose structures quickly and easily. Would like a more detailed manual either in app or a link to an online version. Looking forward to future updates! Worth the 0.99c ### 5/5 — Good for viewing on the go... *2012-07-04, version 1.5* This viewer is good for having a quick look at a protein structure. The rendering is simple, but generally clear. 3D manipulation is intuitive. Not as flexible or powerful as full modelling packages like PyMol. Surface depictions are simplistic and not really useful for interior pockets. But overall, it is a useful app for checking out structures quickly. Well worth the 99¢ ## Frequently asked questions about iMolview ### What kind of molecules can I view with this app?
