Update Issue

After the new update the screen if just blank, nothing appears.

What?

Too detailed.
Won’t save input.
Have had over a year, and has never helped me.

Needs work

App keeps crashing and resetting on my and i have to fix it every time I go to make a weld

McCalc

New app doesn't work! Hit done after input and it kicks you out of app! Last version was flawless. I am screwed!

Needs work

McCalcFusionCalculator crashes each time an entry is attempted from the drop down menus. It doesn't work.

Impossible to use

The update on 8/16/20 has made McCalcFusionCalculator impossible to use, you aren’t able to switch between pipe dimensions ips/dips at all. The black background makes it extremely difficult to read the pressures, the font is basically the same color as the background on all the input interface, I could deal with the random crashing of McCalcFusionCalculator , but now it is completely unusable. Revert or fix the visuals.

November 2015 Update to IPhone

The latest update posted for November 2015 will note update to my iPhone 5s. Tbsp app's message states that the update is incompatible with the iPhone.

Manager

New update is not compatible with iPhone 5c. Sure would be nice if it was.

Nice update but still has flaws, just my opinion.

The new update to McCalcFusionCalculator that took place over the weekend is a nice update. But now you’ve lost the separation between the PP and PE selector at the bottom of the page, and the proper specification selector becomes more difficult to understand unless you know exactly which one you need. Granted this is taught in training, yet can be easily forgotten in the field when you have nothing to reference. It would be nice to give a reference page to the proper specification selection based on area of the world and material as a separate click item at the top of the page. When you were doing PP before there was only 3 selections in the PP category, now there is 21 listed over all for both types. The separation of the 2 materials was much better and easier to navigate. A legend of the Green, Orange and Yellow spots would be nice also. Most of us know this that have been doing this for many years, but many newcomers may not. We don’t want it to be a guessing game for those that don’t. I like the new sound feature included on the ending of each perimeter area for heat soak, open, and cooling, but the sound needs to be louder and more of an attention getter, than a soft cutisy tune. Overall McElroy is the leader in the fusion industry and happy to be a distributor for them. Keep up the good work!

Latest update came with issues

The timer feature is no longer visible besides the start/reset buttons. I can’t see the time. And the black background with the blue lettering in the selection menus make it difficult to read out in the sun which is usually the only place I fuse pipe or use McCalcFusionCalculator. Overall it’s a good app but needs a little attention.

Update:
Previous issues were due to my iPhone being on dark mode. Still would be nice for McCalcFusionCalculator to compatible with dark mode.

Good but needs updated

Good app but needs updated, luckily works. Pipe specifications need updated

McElroy calculator

Good tool, easy to use. Interface pressure could be a drop-down menu by machine and color cylinder instead of entering a number.
On other option could be a option for dissimilar wall thickness

FUSE IT

Needs updated.

Great product

A very quick and accurate way to calculate fusion pressure on the fly. Much quicker than the slide rule and much more accurate.

McCalc Fusion Pressure Calculator

Inituitive, easy to use, great app for fusion professionals! Go McElroy!
