# Flippy the Train vs IEEE Volta

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.

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 October 14, 2026 and September 29, 2026 respectively.
