Triangle Calculator Customer Insights

1. Thanks guysSimple, does what it sets out to do admirably, ads dont cover up anything important, keyboard doesnt cover up any of the input boxes; overall an amazing app.Very useful for solving triangles or double checking my own guess.

2. Hitting Clear fixes this.It good but I wish we can change the letters to the one I have on my problem but overall it still a good app all they need to add is an update where they let you change the lettersCan you do it for inscribed circles and inscribed triangles too please 😌! It's almost no effort.

3. It's also fun to just play with odd angles and lengths of sides....Great app, but sometimes it has an odd glitch where it keeps telling you it doesnt have enough info when it does.

4. They all annoyed me with all adds on filling the screenc or having to keep scrolling down to remember which letter corresponds to which letter when typing in the dims.

5. Thanks Triangle CalculatorI've tried 3 angle finding apps prior finding this one.

6. How high do ramps need to be under back wheels to get motorhome level on this camping spot.

7. This one has none of those issues and just does what it is supposed to.

8. 181mm.

9. Just a single equation added to it.Good start but needs better keyboard.

10. Let me know if im some kind of noob and this feature exists, but it seems like i cannot input values containing fractions or roots.It has shown itself to be incapable of finding the angles for a 3-4-5 triangle.
