The HP-29C was my go-to calculator at my first job after college, and I loved it for its power, ease of use, and flexibility. This is an outstanding and faithful simulation of that calculator. But even taken on its own merits, this is a solid scientific RPN calculator. Excellent functionality, solid programmability, and fast performance. -- JLBiv, 2022-10-07 [View all GO-29 SciRPN reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## GO-29 SciRPN Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Germany | Utilities | #138 | ## GO-29 SciRPN Discovered Keywords -
