Which model? ### 5/5 — Excellent!! *2023-12-19* One of my favorite apps! Simple. Reliable. Bug-free. What an app should be. It is my version of that “fidget” gadget thingy that was so popular. And it allows me to practice my slide rule skills when I don’t have one of my rules with me. Much appreciation to the developer. ### 5/5 — Far and away the best! *2023-09-29* This beautifully done app will provide you with a gut level experience of using a slide rule. It has all of the right scales, and the magnified cursor is a HUGE feature. I used a “slipstick” during my early engineering career, and I sort of missed it. Now I can use one like my old Post Versalog or K&E Log Log Duplex Decitrig. BRAVO TO THE AUTHOR. Look at the all 5-star ratings. The others I tried were like games. ### 5/5 — Slip stick app, lovely retro computing device *2020-07-15* This lovely app recreates to sliderule experience. It has the look and almost the “feel” of the device that was essential to engineering before the advent of the HP calculator. ### 5/5 — Perfect *2020-07-15* Amazingly faithful reproduction of my old slide rule. Worth every penny. ## Frequently asked questions about SlipStick ### What is SlipStick? SlipStick is a digital reproduction of a classic engineering slide rule.
