E-Juice Lab

E-Juice Lab is a calculator for DIY e-liquid mixers, containing:

- two editors / calculators:-
- The "classic" one, that calculates amounts of nicotine base, VG and PG based on desired PG/VG ratio and nicotine strength-
- A mixed base calculator, where you can add arbitrary PG, VG, and VPG (mixed) bases with or without nicotine. You then use sliders to mix.


- searchable aroma library, with some (optional) aromas from common vendors.


- a batch manager for storing your batches. You can set a steeping notification and get notified when your e-liquid has matured

Recipes can be shared/exported/imported via Gmail, DropBox, Google Drive etc.

It may also be worth having a look at the app settings page, where you can set the screen permanent on when e.g viewing batches/recipes, or if you need more accurate PG/VG steps in the editor.

NOTE! If you're using premixed "VPG" bases, select the bottommost option when creating a new recipe !

The app is capable of doing weight calculations. Weight calculations are based on using specific gravities for the various components. The default aroma gravity is taken from the base, e.g PG or alcohol. Advanced users can specify their own specific gravities.

The resulting PG/VG ratio is adjusted where aromas (most of them) are based on PG, with the assumption that the aroma is ~75% PG. (Accurate data is not available)

For more details about calculations, percents, ratios etc, see the app help pages.

From version 2 the app has to be purchased in order to make more than 3 recipes. A lot of time was spent on making this. In addition, having the app free would not be fair to the other app-makers.

Great app easy to use and great export/import feature that's ideal if you have the app installed on multiple devices or want to share with others. The batch feature is also very handy. Overall a well thought out app.

I'm new to the e juice making and got annoyed at most of the recommended calculators. Found this for myself and was immediately impressed with its ease of use and layout. Batch alarms are a bonus. Love it and happy to have paid less than £2 the next day for the full version. Happy to support people who put in good work to provide a great service.

This app is one of the best calculators for DIY e juice production. The only downfall I can find so far is that there isn't a way to sync it with a computer application. If only... Used the free version for a few minutes, then decided to go ahead and buy the full version. For $2, it's well worth the money.

This app would be better than perfect if it included an automated juice/nic stock record. So when you add flavour concentrate to your favorites, you can also add amounts of ml in bottle, so When you use these in your recipes it deducts and keeps a running balance, and warns of low levels to remind you to restock, it could work with nic/pg/vg too.

Its absolutely perfect. Its easy to use and understand. Great for beginners and experts. You can put your mixes into categories and the pre listed aromas are great i have only had to add a few to the list. It does everything you need and more. My only complaint and it is stated in the description is that you can only save 3 recipes in the free version. I think 5 would be just right. Either way I'm paying my 1.99 to help support the devs since they done such a wonderful job.

I think this looks like it will be a great app, but if the devs see this a comment section in the aroma library would be HUGE! I want to write detailed descriptions of the flavors because not all Strawberries, as example, taste the same. And I'd rather keep them in an app than on the bottle or in a notebook. And having it in an app very easily accessible would be great! I was looking for a flavor library with comment capabilities. Other than that you did a great job on the app!

This app is very useful for storing recipes, flavours, and is intuitive and easy to use. However, the formulas for computing VG/PG ratios appear to be incorrect. Assuming all my flavour bases are PG Base (which they are) , the app still calls for adding PG when the flavour percentages are already summing over the desired PG content of my recipe. I've had to make a spreadsheet to correct the numbers the app spits out, which kind of defeats the purpose of buying this app which I've already paid for. If the formulas are corrected it would be a 5 star app in my opinion.

This app is excellent and I have been using it regulary. However it doesn't have the capability to set precise nicotine strength, such as 1.5mg. I am using a sub ohm tank and 2mg or 3mg nicotine may be to high as I require it to be set to 1.2 as an example. Please add this functionality for a 4/5 star review. Also the developer needs to update this app regulary with new features.

Love this app so much I paid for it.. That says a lot since I'm pretty tight. It has everything you'll need to make DIY eJuice and if I had to search for a negative it would be there is no "Max VG" setting so the app will always show you need to add at least a small amount of PG, even if you don't actually do it. Hope Oyvind can add it in a future release.

Yun. A. Apr 23, 2017     

Great app, well thought through. Only 2 things, would be AWESOME if you could import/export your whole recipe library to google drive! When adding a new aroma, would be nice if the aroma field could be blank, now we have to manually remove the "New Aroma" text every time. But this is the nicest ejuice app I have found thus far!

Ben. E. Sep 21, 2015     

Ammended my original review and please accept my apologies for it. The other apps I'd used didn't take non PG components in the aromas and nicotine. The way you've explained it makes perfect sense. Great app - definitely worth paying for. Top notch support from Oyvind too.

Bub. G. Mar 28, 2017     

This app is the best of the best period. If you are unable to mix with this app, give up and buy e liquids from high-priced vendors. Every aspect of mixing his covered in a logical manner. Thank you for the great app, more than happy to spend the $2.

This is an essential tool for every diy who wish to have recipes saved, modified and shared easily. I personally like it so much. Please Ejuice lab guys do add one more thing to this app: Add the ability to set the nicotine VG/PG RATIO TO THE CALCULATION and I will be giving you my 5 stars

Ash. Dec 8, 2016     

This is a really great app. I have been using it for a year now and just love the functionality. Many apps out there but none that make it this easy. Some niggles like, your putting in another new juice, you click done and the cursor doesn't move to the next box ready for typing (just a small niggle seeing as I inputted over 100 concentrates). What woud take this app to the next level is if the developers created a way to share recipes amoungst one another similar to e-liquid-recipes....amazing though

Best juice calculator hands down.. As a newbie I looked around for an easy to use, intuitive app. Found this gem and upgraded five minutes later. Lost one star as only preset aroma/flavor maker's names allowed. Allow us to input the name of our aroma maker and it's perfect!!

Seb. M. Mar 13, 2016     

After trying many calculators I have found this to be the best,easy to use and the design/layout is fantastic, after using for a few days I paid for the premium version as the free one is limited to 3 recipes, well worth the money if you make your own juice, the only thing that would make it better is a cost calculator so you know how much a batch costs,if that's added it will be a 5 star rating.

Bri. L. Oct 12, 2015     

Everything in this app is very well thought out and easy to use. WAY more than I even hoped for in a mixing app. I would consider 4 stars based on the add placements in the free version as its hard to see some parts of the screen and you only get 3 recipes. But I really didn't mind paying for the app as its just that good, this is the only app I have ever bought. Very well worth the $2. ** side note, please add a max VG option.

Sal. K. Aug 11, 2016     

Great app, used it for maybe a year but as I was swapping recipes onto a new phone, it glitches and I get an error 6 message so can't load more and can't find how to push a reinstall to sort the problem! Been fabulous up to now, made litres of good reliable juice. (Edit spontaneously sorted itself out, I'm mixing happily again :) )

Bri. G. Nov 18, 2015     

This is a nice app but... I wish the steep notification worked. And the other thing I can think of right now is I wish there was a way to add notes to individual flavors like percentage when used alone and notes about flavor and what it mixes well with. When you have 30+ flavors sometimes it's hard to remember everything about all of them. I know you can add notes to recipes and batches but I want to be able to scroll down the list, pick a flavor and read about it instead of trying to find the recipe.

Dyl. L. Dec 3, 2016     

What the title says. For some reason you can only set the nicotine base at 100% PG or 100% VG makes it kinda worthless to me as I use 50/50. But, other than this it's a neat little tool and I actually like the layout of this one better than the one I had to switch to.

Col. Jan 14, 2017     

This app is the most thought out, simple yet powerful, juice calculator you could ask for. Setting for screen always on while in selected screens, batch alarm with batch id#, separate tabs that show only values for your choice of measurement, recipe clone, effortlessly adjust amount of recipes. I could go on and on. The Devils in the details. Has everything I wanted, and much more I didn't realize I wanted. $2 is a steal. Truly impressed how well it is put together. Thanks for the great work!

Hol. E. A. Jan 13, 2017     

Lasted 2 minutes. Tried and failed to add flavour percentage and no matter how many times I pressed OK it wouldn't close the box and progress. Tried many ways including adding the % to no avail. Don't know if it's because it is just for phones however I'm using a respectable tablet here. Had to uninstall. No good to me.

jim. s. Feb 4, 2017     

The pg calculation is off a little. I don't think it takes in consideration of the pg in the nicotine base, so pg calculation will be a little high I use an online database which is very well known, but this app is handy to have on your phone. If they could fix the pg calculation to include the base nicotine % then it would be correct

Jes. H. Nov 17, 2016     

So far the best juice-app I've come across.. However, I'd love to have a proper sync-function in the app. It could use one or two of the most common cloud-storage apps available (Dropbox, Google Drive etc..) to automatically download when started and upload when exited. Would help a low for people using more than one device. I have no idea how difficult something like this might be to implement, but it would make this a perfect app for me. For now 4/5, still great, but not perfect.

Mic. F. Aug 23, 2016     

Ok... I had to change my rating from 4 stars to 1 star unfortunately. I upgraded my phone from the note 4 to the note 7 and now it is making me increase my VG/PG ratio by increments of 5 rather than 1 like it did on my old phone. Also if you could make there be the ability to make nicotine levels such as 1.5 rather than just 1, 2, 4, 5, 10, 12 etc etc thatd be great. Fix even just the first thing plz.so i dont have to a new app. I have to be able to change those by 1s, not 5, or ill have to go to liquix

This is so far the best I've used on android and even on pc, I recently had to do a hard reset and i think it would be nice if it automatically uploaded your recipes to a cloud service like Dropbox or Google Drive
