Tersa is a touch-first workspace for learning, reviewing, and tuning small analog and RF circuits on iPhone and iPad. Build editable schematics, configure DC operating point, DC sweep, AC and transient analyses, and inspect measurements on clear plots. For linear two-port work, review S11, S12, S21 and S22, return and insertion loss, and raw complex data on a Smith chart. Use local sample projects to explore RC and LC filters. Change supported component values with the tuner and run the analysis again without rebuilding the project. Import supported SPICE model cards and subcircuits when a circuit needs them. Simulation runs locally on the device. Results depend on the circuit, models, and numerical settings and must be independently verified before fabrication or safety-related use.

Verdict
The clearest difference is review sentiment: Tersa at 100% against Expo Go's 56%. Tersa also leads on ads (none vs shown) and monetization model (free vs ad-supported). Expo Go's advantage is chart position (#8 vs unranked). On price, update cadence, in-app purchases and device support there is nothing between them.
