Good but needs extra fx’s. Too basic.
It’s a good app, but I cannot find a way of converting decimal hours to hours and minutes. H.dd to HH:MM. Needs a D:M:S option.
Best app on my phone
I use it 5 days a week but update will not download
Simple, easy and intuitive
Perfect for constantly using simple custom formulas with minimum of keystrokes
Best Application
this is the best app i have in my phone! kudos to the publisher!
Good app for custom Formulas
I purchased this app because I am in the directional drilling industry. I was able to write some of the common formulas that I use every day into it and so far it is working great!
Anyone who uses angles like co-sign, sine and tangent formulas should know you have to write the angle and then convert to radiaons. Us tang(angle*PI/180) it’ll work well.
Very good so far and exactly what I needed. A variable based formula saver.

Not ready
Formulas can be created, but not functional.
Extremely annoying
I was using this app and THREE things made be delete it. 1. It asks a bunch of stuff at the beginning and even to upgrade to v 2.5. Wouldn't we already have that? 2. The question mark tells you how to make a formula, but you can't get out causing you to have to get out of the app and get back on, WHICH CAUSES YOU TO LOSE ALL OF YOUR PROGRESS. 3. The formula maker only shows 1 input field/constant field. Not helpful at all. Please fix this stupid app.

Perfect
Does everything you need to write your own formulas.
Buggy
Buggy, fix updates
Horrible
This was a five star app until the latest update. The redesigned UI is terrible, clumsy, and confusing.
It won't let me restore my purchase to remove ads.
It deleted all the custom formula calculators I made using the previous version. It's useless now.
Please fix it...like it was!!

Crashes on upgrading existing formulas
I had two simple formulas that I used before the app updated. Now it launches and says 'Upgrading' and crashes - it's unusable now and I will have to reinstall it and recreate my formulas again
Update non functional
Same as #3 above. Bug fix it now please!
Unresponsive
I had this app previously and it worked great but since the update the app has deleted my old formulae and become unresponsive. It stays on the home screen and I can't hit the + to add new formulae. Hope there will be an update to fix this soon!
Update Non-functional
The update has rendered the app useless. When launched an upgrading message appears and then the app crashes.
Crash
This updated version keeps on crashing
Does not go beyond 3 decimals
I paid for the "pro" upgrade, it still will not go beyond 3 decimal places- stay away from this!!
Great app
Thank you for creating this app I can think of a lot of applications. You have done a fantastic job developing this app.
If function
Thank you for very useful app
Please add IF function
Please add IF function
Really very good!
This app is actually very good and does exactly what I'd hoped for.
What a relief
I used to love Mathpad which was a similar program on my old Palm device. I have been searching high and low for a replacement and was ecstatic when I came this program. For free form formula entry and solutions and the ability to store the formulas this works very well!
