User Reviews

TechCalc+ Calculator is highly praised for its comprehensive scientific capabilities, customizable interface, and excellent developer support. It serves multiple disciplines effectively with features like unit conversion, graphing, and extensive scientific references. Users value its affordability and continual updates. However, some users find the editing interface unintuitive, have issues with number formatting, and would like more standard conversions for data units. Despite minor usability concerns, it remains one of the most versatile and reliable calculator apps available, strongly recommended by professionals and students alike.

Pros

Extensive scientific and engineering features making it suitable for professionals and students in various fields such as programming, physics, chemistry, and engineering.
Highly customizable and versatile, allowing users to configure the calculator according to their needs.
Excellent customer service and developer responsiveness, with developers actively adding requested features.
Inclusion of advanced tools such as unit converters, graphing calculator, and scientific references including periodic table and formulas.
Affordable pro version providing even more powerful features while maintaining value for money.

Cons

Some issues with user interface interaction such as difficult editing and arrow key behavior in edit mode.
The formatting of large numbers with commas is not standard and can be confusing for some users.
Data storage unit conversions follow IEC standards (1 kb = 1000 bytes), which may not align with common practice in computing where 1 kb = 1024 bytes, causing calculation discrepancies.
Limited or unclear options to copy results to clipboard, affecting workflow efficiency for frequent conversions like decimal to binary.

Recent reviews

Worth the modest fee. If you are a computer engineer be aware that data storage calculations use the IEC "standard" so 1 kilobyte is converted to 1000 bytes and not 1024 which makes no sense since it not a power of 2/binary number). This will throw off your calculations if you use the actual 1kb=1024 bytes conversion (the practicing standard). I've been a computer engineer for 40 years and have never seen anyone in IT convert 1 kb to 1000. I wish I had the option to not use the IEC values.

Fantastic calculator app. I use it very frequently while doing programming. Would be great to see EV car efficiency conversions added. eg. Wh/mile to kWh/100km etc.
