# EleMend vs Science Simulations

The clearest difference is ads: Science Simulations at none against EleMend's shown. Science Simulations also leads on review sentiment (100% vs 87%) and monetization model (free vs ad-supported). EleMend's advantage is update cadence (every 5 days vs every 3 months) and ratings volume (59 vs 4). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Science Simulations holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: EleMend has 59 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 87% of EleMend's written reviews are positive against 100% of Science Simulations's.

EleMend ships an update every 5 days, Science Simulations every 3 months. The most recent releases landed on September 18, 2026 and August 17, 2026 respectively.
