Drop Mopper Lab turns scattered chemistry concepts into structured research — build molecular blueprints, track variants and timelines, and keep an entire knowledge library at your bench. Everything stays on your device.
Six connected tools that take a loose compound idea and turn it into an organized, evolving project you can return to whenever inspiration strikes.
Assemble molecular structures with drag-and-connect node tools, then watch the layout respond as your designs grow in complexity.
Analyze structural compositions and read live stability indicators, so you can compare concepts and refine hypotheses with confidence.
Keep work in categorized projects with variant tracking, development timelines, and detailed notes you can revisit and expand over time.
Browse an extensive catalog of elements, reactions, lab techniques, and compound records — context that's always one tap from your work.
Integrated formula tools and calculators support everyday planning and investigation — including the live molar-mass bench below.
Track milestones, monitor progress, and surface contextual recommendations that point toward new directions worth exploring.
A taste of the integrated calculators inside the app. Type any chemical formula — including groups like Ca(OH)2 or Fe2(SO4)3 — and watch its molar mass resolve in real time, entirely in your browser.
The bench parses nested groups and counts every atom, then breaks down each element's contribution to the total weight. Tap an example to load it.
⚗️We're the team behind Drop Mopper Lab — chemists at heart and builders by trade, united by a simple conviction: every molecule begins as an idea, and ideas deserve somewhere durable to evolve. We made the workspace we always wished we'd had at the bench.
🔭Our mission is to turn scattered thinking into structured science. Students, molecular explorers, and independent researchers shouldn't have to juggle loose notes, half-finished sketches, and forgotten files — they should have one calm, organized environment built for the way real investigation actually unfolds.
🧪So the app lets you construct molecular blueprints with node-based tools, analyze structural compositions, and watch stability indicators respond as your designs grow in complexity. Manage research portfolios with categorized projects, variant tracking, and development timelines; browse a deep reference library of elements, reactions, and lab techniques; and lean on integrated calculators and formula tools whenever planning gets technical.
✨Drop Mopper Lab — where loose ideas crystallize into real research.
Drop Mopper Lab is built on a straightforward principle: the app does not collect, store, or transmit any of your data. Everything you create lives entirely on your own device. Here's exactly what that means.
Nothing. The app does not ask you to create an account and does not gather your name, email, phone number, location, or any other identifier. We run no analytics and collect no usage statistics. Every molecular blueprint, compound record, reaction note, atomic structure, experimental observation, project, variant, timeline, and note you create stays on your device and is never seen by us.
Because we never collect any information, there is nothing for us to use, read, analyze, profile, share, or sell. All features — the node-based builder, structural analysis, stability indicators, the reference library, and the calculators and formula tools — run entirely on-device. Your work is never processed on our servers, because it never reaches them.
All of your research is stored locally, in the app's own space on your device. There is no cloud sync, no remote backup, and no transmission of your projects to us or to anyone else. Your data stays where you put it: with you.
The app integrates no third-party analytics, advertising networks, trackers, or data-harvesting SDKs. There are no embedded marketing pixels and no behavioral profiling tools. Nothing inside the app reports back to an outside party.
Since your information never leaves your device, the most significant privacy risks — interception in transit, server breaches, leaked databases — simply don't apply. Your research benefits from the security controls of your own device, and we keep our external footprint as close to zero as possible.
Because we collect no data from anyone, we collect no data from children. The app does not knowingly gather personal information from users under the age of 13, and our no-collection design keeps it aligned with the spirit of COPPA for younger learners exploring chemistry.
You are always in full control of your content. You can edit or delete any project, compound, or note at any time inside the app. Because there are no accounts and no backups held by us, removing the app from your device permanently removes the data stored with it. There is nothing to request from us, because we hold nothing about you.
We may update this policy from time to time as the app evolves. When we do, we'll revise the Effective Date shown above so you can always see when the current version took effect. Our core commitment — no collection, no storage, no transmission — is not something we intend to change.
Questions about this policy are always welcome. You can reach us at privacy@dropmopperlabapp.com.
🧫We love hearing from the people who actually use Drop Mopper Lab. Whether you're deep in a research portfolio or just getting your first compound onto the canvas, your input shapes what we build next.
