# iCircuit vs TI

The clearest difference is price: iCircuit at $12.99 against TI's $29.99. iCircuit also leads on update cadence (every 4 weeks vs every 6 months) and device support (3 vs 1). TI's advantage is rating (4.6 vs 3.9) and in-app purchases (none vs 2). On review sentiment, ratings volume, ads and monetization model there is nothing between them.

iCircuit costs $12.99 and TI $29.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month. TI asks for nothing beyond the download.

TI holds the better App Store score, 4.6 against 3.9. Both are backed by a comparable volume of ratings — 154 and 406 respectively. Written reviews point the same way: 61% of iCircuit's written reviews are positive against 65% of TI's.

iCircuit ships an update every 4 weeks, TI every 6 months. The most recent releases landed on November 10, 2026 and November 1, 2026 respectively.
