This app is very simple, hence very enjoyable, to use. Just plug in a couple of pieces of information and you get the answer you seek. -- PairedOut, 2025-04-09 ### ***** "Survey math." Quick and easy way to find distance and angles!! -- chimeclock, 2024-07-15 ### ***-- "Very Unclear Upgrade Options" There are several options for upgrade! But nothing at all to identify a single additional feature, other than how many decimal places are added beyond 0.9. You want my money, give me a slightly better reason for why I should gov it to you, rather than another app that gives me a better representation of the triangle. There are others apps that are free and give you 10 decimal places automatically. This app will help you with basic trig. There are better ones out there for free. So you go into the scrap app pile! -- FTMFF, 2023-07-12 ### ***** "angles of a right triangle" Very easy to use. Fast and easy -- raftered, 2022-01-03 ### ***** "It works" I’m in a class where I need to use trig but I never learned it. This app is a life saver. I even paid to have the premium version. -- Alex5884219745899, 2021-12-06 ### ***** "9th grader review on trig help app" I I have never too trigonometry before this school year and this app helped me out tremendously -- AHGAKGADGAKG, 2021-06-21 ### ***** "Underrated" This app is SOOO helpful especially now in quarantine where it’s harder to learn this app has helped me soo much for geometry 10/10 recommend ❤️ -- wolfieFang709, 2021-03-31 ### ***** "Amazing app!!!!!" If I could give it at a higher rating I would!!!! It’s so easy to use and it’s straight to the point!!! -- Des_🌺, 2020-09-01 [View all Trigonometry Help Lite reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Trigonometry Help Lite In-App Purchases | Item | Price | |------|-------| | Trig Help Premium | $5.99 | ## Trigonometry Help Lite Discovered Keywords -
