The app allows to search compounds through PubChem and helps to keep information on solutions made of those compounds. I. Compounds Tab Search the open chemistry database 'PubChem' at the National Institutes of Health (NIH) for chemical compounds. The app helps to find a compound by name from the collection of more than 111 million compounds. It downloads and stores the molecular formula, weight, and structure. Compounds 1. Selecting the "Compounds" tab will present a list of compounds. - If there are any solutions made of a compound, a droplet will appear next to the compound's name. 2. When a compound is selected, a view with the detailed information will appear. Follow the instruction in "Details for a compound". 3. When the "+" button is selected, a view for search will appear. Follow the instruction in "Search for a compound". Details for a compound 1. Click "Compounds" to return back to the table of compounds. 2. Click the magnifier icon to open the compound's PubChem page in the user's default web browser. 3. Click the trashcan icon to delete the compound. This function may not be available if there is a solution made of the compound. 4. Click one of the solutions made of the compound to display the information. See "Details for a solution" below. 5. Click "3D" to display a 3D structure. Use pan and pinch gestures to rotate and zoom the scene. Search for a compound 1. Select "Compound Name" ("CID") and type a compound name (PubChem CID). 2. Click "Search" to connect to PubChem. An activity indicator will appear until the search is finished. - If the search succeeds, the downloaded information will appear. - If the search fails, an alert will appear. 3. Click "Save" to store the information about a compound. 4. Click "Cancel" to dismiss the scene. II. Solutions Tab Choose compounds downloaded from PubChem and make a solution. The app allows to record a list of compounds with amounts dissolved in a solution. For the saved solutions, the app displays their compositions in gram and mol. Solutions 1. Selecting the "Solutions" tab will present a list of solutions. 2. When a solution is selected, a view with the detailed information will appear. Follow the instruction in "Details for a solution". 3. When the "+" button is selected, a view for search will appear. Follow the instruction in "Making a solution". Details for a solution 1. Click "Solutions" to return back to the table of compounds. 2. Click the 'action' icon to share a csv file containig the information about the solution. 3. Click the trashcan icon to delete the solution. 5. Choose the unit among gram, mg, mol, and mM. 6. Select one of compounds to display its structure and formula. See "Mini details for a compound" below. Making a solution 1. Click "Add Compounds" to bring a collection of compounds. See "Compounds collection" below. 2. The names of the compounds selected from "Compounds collection" will be displayed as “Solution Label”. A user can edit “Solution Label”. 3. The unit for the amount can be chosen among gram, mg, mol, and mM. 4. The amount may be entered. 5. Click "Save" to create and add a new solution. 6. Click "Cancel" to dismiss the scene. Compounds collection 1. Select or deselect compounds by clicking the images of compounds. 2. Selected compounds will be displayed. 3. Click "Done" to return back to "Making a solution". 5. Click "Cancel" to dismiss the scene.

Atomizer AR turns your iPhone or iPad into a portable quantum chemistry lab. Visualize atomic and molecular orbitals in 3D, render electron density clouds, and step into immersive WebXR augmented reality where molecules sit on your desk at real-world scale. — WHAT YOU CAN DO — • Explore atomic orbitals computed from real hydrogenic wavefunctions: 1s, 2p, 3d, 4f and beyond, with adjustable shell glow and Bohmian trajectory animation. • View any molecule's molecular orbitals (HOMO, LUMO, intermediates) computed via PySCF on the cloud, then rendered as interactive isosurfaces. • See ball-and-stick models in WebXR augmented reality. Tap "View in AR", point at a flat surface, place the molecule on a table, then pinch to scale and drag to rotate. • Pair your phone with the desktop using Atomizer Remote: enter a 4-letter code, then tilt your phone to control the on-screen molecule with your gyroscope. Live preview streams back to your phone in real time. • Browse 40+ molecules — water, glucose, caffeine, benzene, ammonia, ethanol, methane, sulfuric acid and more — with energy diagrams, dipole arrows, lone pairs (VSEPR) and MO correlation diagrams. • Calculate molar mass live from any chemical formula, including parenthesised groups like Ca(OH)₂ and (NH₄)₂SO₄, with per-element breakdown. • Balance equations, run stoichiometry, sketch molecules in 2D, and explore reaction pathways. — SUBSCRIPTIONS — Free: 5 molecule renders per period. All calculator tools and full periodic table. Californium Pass — $2.99/month. 50 renders monthly, priority compute queue. Einsteinium Pass — $6.99/month. Unlimited renders, GLTF export for AR/3D printing, protein visualization, priority support. Auto-renews unless cancelled at least 24 hours before the period ends. Cancel anytime in Settings → Apple ID → Subscriptions. Subscriptions sync across iPhone, iPad, and electronvisual.org.

Verdict
The clearest difference is rating: Search PubChem at 5.0 against Atomizer AR's 4.0. Search PubChem also leads on in-app purchases (none vs 4). Atomizer AR's advantage is update cadence (every 10 days vs every 9 months) and review sentiment (100% vs 75%). On price, ratings volume and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Atomizer AR sells 4 in-app purchases, starting at $4.99 per month. Search PubChem asks for nothing beyond the download.
Search PubChem holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 5 and 3 respectively. Written reviews complicate that: 75% of Search PubChem's written reviews are positive against 100% of Atomizer AR's, so the app with the better star average is not the one people write more warmly about.
Search PubChem ships an update every 9 months, Atomizer AR every 10 days. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
