# RC Circuit vs DigiBOX

The clearest difference is rating: RC Circuit at 4.8 against DigiBOX's 3.0. RC Circuit also leads on ratings volume (5 vs 1). DigiBOX's advantage is in-app purchases (none vs 1) and update cadence (every 3 days vs every 6 months). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. RC Circuit sells 1 one-off in-app purchase. DigiBOX asks for nothing beyond the download.

RC Circuit holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: RC Circuit has 5 ratings behind it against 1, so its average is the more settled of the two.

RC Circuit ships an update every 6 months, DigiBOX every 3 days. The most recent releases landed on November 1, 2026 and October 29, 2026 respectively.
