Verdict
The clearest difference is rating: Circuitry at 3.9 against VivaLing's 3.0. Circuitry also leads on ratings volume (155 vs 2) and review sentiment (51% vs 33%). VivaLing's advantage is update cadence (every 6 weeks vs every 4 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.
Circuitry holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Circuitry has 155 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 33% of VivaLing's written reviews are positive against 51% of Circuitry's.
VivaLing ships an update every 6 weeks, Circuitry every 4 months. The most recent releases landed on September 10, 2026 and September 13, 2026 respectively.
