It makes it super easy to pour any sized batch. If I had one thing I’d change. It would be great to have a “convert to metric” function, where I could enter the weight in oz and have it convert that to grams for me. It’s not hard to do so manually, but it would be convenient. Over all great application! ### 1/5 — Better before the update *2021-01-25* The math is different now!!! I know this because previously it would fill wax perfectly, at the same spot the water weight would be at. Now I have left over. Every time. I just tried a status jar and it’s a joke how much I had left over. Why did you mess with this?!! Last week I used it to make clamshells and never had an issue before. It should have made 10 clamshells and it ended up making 12. I’m glad I screen shot my previous calculations because otherwise my candles would be off too. Previously the calculator said for 6.6 of water oz with 10% FO that I would need- 5.3 oz of wax and .6 FO for one candle. Now it says I would need 5.46 of wax, and .55 oz of FO. ### 5/5 — The new update is an excellent improvement *2021-01-21* To all the users giving the developer negative reviews...please understand that it was the OLD version that was the problem. It rounded off the math calculations. The new version is MUCH more accurate. That is why you are seeing differences in the answers. **Developer response:** Check out the newest update which addresses those issues ### 3/5 — New update *2021-01-19* I loved this calculator. It’s all I’ve ever used. I’m just not loving the new update. The calculations look like they’re in the background. They were much more visible with the other version. **Developer response:** Thanks for the input. I will check that out. ### 3/5 — Calculations changed *2021-01-17* Why did the calculations change after the update? ### 3/5 — Calculations are off sometimes *2021-01-13* Some of the calculations are spot on at times and then other times it’s completely off. **Developer response:** If you can be a little more specific, I would love to help. I have tested this on different quantities and it comes close every time. ### 5/5 — Really Helps *2021-01-11* This calculator really helps me save wax. The look of the updated version is basic but I still works just as good. Does grams and oz. I don’t make my ca flea without this now. ### 3/5 — Ok *2020-12-23* Very simple to use which I love but the fragrance load is wayyy ### 3/5 — Cool app but... *2020-12-16* The math doesn’t add up. 9oz candle 8% load The app says 7.4 oz wax plus 0.7 oz FO. That equals 8.1 oz not 9oz. ??? **Developer response:** Are you measuring using water? This app is to estimate how much wax you will need to fill a vessel, by measuring water weight. Wax is more dense than water so you should get a lower number. The explanation is in the help section in the app. If have anymore questions, please reach out. ### 5/5 — Candle Calculator Makes Newbie Smile *2020-12-16* Did my first batch using Candle Calculator and I must admit was I skeptical about its accuracy. After pouring the last drop into the last candle container, there was no wax/fragrance mix left except what was on the side of the pouring container, of course.
