Tap OChem vs Crys

"Awesome" writes a reviewer! More reviewers comments! "I have used it for all of my exams so far and it is extraordinarily helpful." "This is the best investment that you can make to visualize the reactions. There are a ton of them and they are AWESOME!!!!!" Another reviewer writes “Covers all of the major topics and the videos help me visualize the details of the molecules and reactions”…“Could almost replace a whole textbook.” While we never claim to cover an entire organic chemistry class, with content added in each update (major free updates each year since publishing ten years ago!), Tap OChem is the app that delivers! The reactions and concepts included are many from the one year sequence of undergraduate organic chemistry that is offered at all major colleges and universities. Students have told us that this app was essential in their preparation for the MCAT. Whether you are currently in the one year sequence of classes or reviewing for the MCAT, or PCAT, OAT, and DAT, this app will help! Designed by two award winning chemists with over 48 years of combined experience teaching at major universities, Tap OChem makes organic chemistry reaction come to life for each included reaction or concept. The following animations are currently included: Substitution reactions (20 animations), Elimination reactions (11 animations), Alkene Chemistry (15 animations), Free Radical Chemistry (4 animations), Alkyne Chemistry (7 animations), Epoxide chemistry (4 animations), Benzene chemistry (10 animations), Diene Chemistry (8 animations), Carbonyl Chemistry (8 animations), Major concepts (62+ animations), and Molecules in Motion (35+ animations). The Concepts section includes valence bond theory, molecular orbital theory, electrostatic potential maps, radical spin density maps, alkene stability, dienes and stability, conformational analysis of alkanes and cyclohexane, etc. We've just started adding information on intermolecular interactions and plan on more spectroscopic topics! One animation on dipole/dipole attraction was added. Two animations, one focused on the introduction to IR spectroscopy are included. We are developing and updating more animations for future updates! Each animation has an accompanying text that drills down to the main facts of each reaction or concept. These are in FULL COLOR! They are short, handy, descriptions with important information regarding each reaction or concept. In the case of reaction animations, the concise scrollable text descriptions include electron pushing. We will continue to update the app with future releases. Tap OChem is native to both iPhones and iPads! In addition to the animations being very sharp on your iPhone and iPad, they are of excellent quality when projected (iPhone 4S and iPhone 6s, 6s Plus, 7, 7 Plus, 8, 8 Plus, X, 11, 12, and later, iPad 2 and later, using appropriate adapters) in a classroom. For the iPhone 6s and later; and iPad Air 1 and 2 and later, an appropriate adapter is needed like Lightning Digital AV Adapter (this is an HDMI adapter), or a USB C to HDMI adapter, or a Lightning to VGA Adapter.

Crys-CAST brings crystal and molecular structure viewing, geometry analysis, and presentation tools to iPhone and iPad. OPEN AND EXPLORE Open CIF, XYZ, PDB, MOL, SDF, MOL2, and RES files from Files or other apps. Explore asymmetric units, unit cells, and supercells with ball-and-stick, Spacefill, coordination polyhedra, and thermal ellipsoids when suitable displacement data is available. Rotate, zoom, and view structures along crystallographic directions. MEASURE AND ANALYZE Inspect bond lengths, bond angles, and geometric hydrogen-bond candidates, grouped by type with clear symmetry details. Combine selected length, angle, and hydrogen-bond labels directly on the structure. Distinguish coordinate-calculated values from matching CIF-reported geometry, and export compact bond-length and bond-angle tables as TXT or Excel-compatible CSV. Explore simulated powder X-ray diffraction patterns, BFDH morphology, and geometric pore analysis. Display pore space alone or together with the crystal structure. BUILD YOUR COLLECTION Organize structures in My Database. Add files from History or import structure files and ZIP, RAR, or 7z archives into a chosen collection. Name entries, save viewing states, and export collections for reuse. CREATE PRESENTATION MATERIALS Save structure images and record GIF or MP4 animations with resolution and frame-rate presets and custom duration. Use automatic rotation or adjust the view while recording. Animation exports contain the structure viewer without interface controls or sound. MAKE THE VIEW YOUR OWN Use a consistent interface on iPhone and iPad, choose light or dark appearance, and customize backgrounds, unit-cell lines, axes, and scale bars. SCIENTIFIC SCOPE Calculated geometry, hydrogen-bond candidates, pore results, and other analyses depend on the input data and selected settings. They support visualization and interpretation but do not replace structure refinement or experimental validation. Missing hydrogen positions are not inferred. Actual recording frame rate depends on device performance and structure complexity.
