# Constellation Energy Lines vs Spy Synapse

The clearest difference is update cadence: Spy Synapse at every 4 days against Constellation Energy Lines's every 9 months. Spy Synapse also leads on rating (5.0 vs 4.7). Constellation Energy Lines's advantage is ratings volume (6 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Constellation Energy Lines sells 7 one-off in-app purchases and Spy Synapse sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Spy Synapse holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Constellation Energy Lines has 6 ratings behind it against 1, so its average is the more settled of the two.
