# EcoNet vs Optimal°

The clearest difference is review sentiment: Optimal° at 60% against EcoNet's 16%. Optimal° also leads on rating (4.9 vs 4.4). EcoNet's advantage is ratings volume (13K vs 7) and update cadence (every 5 weeks vs every 5 months). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Optimal° holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: EcoNet has 13K ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 16% of EcoNet's written reviews are positive against 60% of Optimal°'s.

EcoNet ships an update every 5 weeks, Optimal° every 5 months. The most recent releases landed on September 24, 2026 and June 1, 2026 respectively.
