Build a train track to solve digital circuitry puzzles! Flippy the Train rides the rails, flipping switches to model basic digital circuitry: NOT, AND, and OR logic gates. After building these basics, reuse them in larger tracks to create the more-complex XOR gate and half-adder. What is the fewest number of track segments required to build a half-adder? Includes a sandbox mode for creating arbitrary track for Flippy to ride.

Integrated Circuits (ICs) are at the core of our hi-tech world. They are inside everything electronics. In the coming robot/IoT/AR/VR era, the application and deployment of ICs will become even more prolific and widespread. IEEE Volta is an app developed by IEEE Solid-State Circuits Society (SSCS) aiming at educating the general public about the importance and the history of ICs over the years. The application is named after Alessandro Volta, a pioneer of electricity and power. The puzzle themes feature the most significant ICs that have changed our way of living. Through learning about these ICs, users gain the historic perspective about this fascinating field and shed some light on what the future ICs may bring for us.

Verdict
The clearest difference is update cadence: IEEE Volta at fortnightly against Flippy the Train's every 6 months. IEEE Volta also leads on iOS requirement (8.0 vs 13.0). Flippy the Train's advantage is rating (5.0 vs 4.8). On price, review sentiment, ratings volume and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Flippy the Train holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 5 and 4 respectively. Written reviews split almost evenly too, at 100% and 100% positive.
Flippy the Train ships an update every 6 months, IEEE Volta fortnightly. The most recent releases landed on September 28, 2026 and September 29, 2026 respectively.
