very good experience
This is has info about Total synthesis by Targets and Authors Found it so useful my Total Synthesis study
must have
Very complex
Excellent app for designing the chemistry and drug development
🛰️📡🛰️siTes.TogeTher.minimizer🛰️📡🛰️
Accurate and essential 👌
Nice app
Brilliant app and vast list of interesting reactions. Truly amazing app. I just have one suggestion, if we could open the reaction in vertical view..... It would be great
great for chem students
Very nice
Excellently built. I like the app content and the built structure. It is stable. It requires exit button as well as please do add all the organic synthesis reaction.
Greens are a great place to work for and the most important thing is the fact that
Very useful for chemist
Nice app to train organic synthesis skills
'Chemistry by design' is definitely a must-have app for those who are interested into both total synthesis and reaction design. The app is superp and very straightforward to use, but it has just a minuscule problem. If you don't use it for a short period of time or if you decide to open another app, you certainly will loss the progress you've made, i.e., the reaction you were checking.
nice app. Too much helpful. wonderful app.
Excellent app!! One thing could be still be improved: when the app goes in a background mode, the on going synthesis is lost and you are back on the starting page. If it was possible to get back where you left that would be fantastic! Thanks for the wonderful work!
v good app for researchers
It's a really helpful app
Great database and tool for chemist...
Should I search manually
Wonderful app for updating in total synthesis. If possible please provide explanation of few difficult chemical transformation. Thanks for making this app.
Very good. Excellent
Fantastic
Best app for organic chemists ir Playstore
Nice
Very awesome
Great app, love it! But it restarts everytime you lock the screen or switch to another app. Really annoying you want to look for a reagent's info on internet. And no offline mode available! Real shame for such a useful app! Please work on it!
Nice
Nice
organic researchers will love it
Good
Good!!!

Great app
Superb app to stay in touch with complex molecule synthesis... Thank you
It's very useful for chemistry students
Great app... But bit laggy..!
why I can't able to download this app
Useful
Good
Excellent app for the chemistry students and Faculty
Good
Good. New molecules update is needed.
Such a perfect app love it.i have been using this app for 3 years for my organic synthesis
Tremendous in terms of the library of syntheses. Could be better if the reaction mechanism pathways could be shown.
No
Nice
Great app! Seriously fantastic. Found a couple errors here and there, but they are few and far between. Wishlist: a "new molecules" filter and a way to bookmark favorite syntheses.
Best
It works not pls do not install it plzzzzzzz
This app is awesome but really needs an offline mode! Can't get anything unless connected to the Internet... Kind of annoying ! Keep it up!
Good
Good collection of total syntheses and drug syntheses. Only major complaint is that the app is unable to keep your place if the phone or tablet screen shuts off
Its an outstanding app
Good
This app is very usefull.... many synthesis routes of compound
Nice app
Nice one must help full
Very useful for chemistry
Superb
Luved it
useful
I like it
The app is great, there are tons of synthetic routes to refresh ( or learn) concepts of organic chemistry... but the interface could be improve. Also it is annoying that the app closes automatically when the screen is off or when you change the app . It would be great to be able to keep reading from the point it was before the app got close, so the reading of long synthetic routes could be more enjoyable.
Amazing
Very good app for student and teachers too
Super
It's really nice app!
Good
I cannot think of any other app which could beat this one anytime soon !!!

Very nice... I ever seen before

Very nice apps.
Exellant app for organic chemistry
It's a good app with a great database. But it has a basic gui that can be better.
Superb
Gud app
ok
, the UI might need some refreshment but its database is huge and it provides a good tool to practice one's synthetic skills and knowledge.
Pharma ref....
So no problem in download
Love it....
Awesome
Very good app. A lot of pharmaceuticals with all reactions... 5 stars from me...
Awesomely awesome!!
Still like it,because love to study much much.
Waste of time
Fast search, robust database. GUI needs improvement;)
fine app to test application of basic
Very very gd app.very use full to studys
Great app, one of the very few to go beyond just basics. Keep up the good work.
It is a very helpful for study of chemistry
The app no longer works since the new 4.4 kitkat update! Guys please fix it!! Thank you in advance, very helpful otherwise!
Work well :)
I thought this would be great for studying but it's very laggy :( the mechanism won't show anything at all
superb app
I need dis
not at all user friendly!!
Thought out would help out in the basics but its more of a pharmaceutical understanding app.
Thank u so much...
Good but would be much better if mechanisms were included.
I quite like this application, it's very useful for graduate-level synthetic chemistry. Unfortunately, it doesn't seem to work without a Data Connection.
Great app, im still learning some concepts in synthetic chemistry, great effort put into making this app, and it comes at no cost. Excellent app.
I rated this app with 3 Stars (ONLY) because of the complexity of the reactions (AND) the interface's 'look', which is a bit 'clunky'. Nevertheless, the app is extremely useful for GRADUATE LEVEL and CLINICAL students. Update the app to show examples of embedded functional groups and I'll give it 4 Stars.
Great app
Nice
Excellent app
First, this app is amazing. It contains great information in a totally free package. future updates would potentially include retrosynthetic analyses, and perhaps a better touch-friendly interface. the scroll bar is out of place on a touch screen phone. Again, thank you or all of the hard work that went into making this app what it is.
Great synthesis app. A must for organic grad students.
Would be great otherwise.
Brilliant app for testing, revising, and expanding synthetic routes!
I am a grad chemist and this has been a very fun app with a plathora of reactions to review and test you knowledge of synthesis.
