Terminal naming is now more consistent across the editor, inspector, component previews, and oscilloscope. We also improved net label refresh when reopening circuits, along with additional visual polish and bug fixes. ### 1.2.1 — 2026-03-18 Schematic Thumbnails — Component lists now display real circuit schematic previews instead of generic icons, making it easier to find the part you need. Stamp Mode — Select a component and tap repeatedly to place multiple copies with the same properties. Perfect for quickly populating your circuit with identical parts like resistors or capacitors. Collision Detection — Components can no longer overlap. A smart placement system automatically finds the nearest valid position and shows visual feedback during drag. Toolbar Improvements — Toolbar buttons now show contextual enabled, disabled, and active states for a clearer editing experience. ### 1.2.0 — 2026-03-17 Oscilloscope: More stable trigger alignment, reduced waveform drift, and better auto-scaling across a wider range of signals. Simulator: Refined internal shunt path handling to reduce floating-node issues and improve convergence. New Components: Common Anode and Common Cathode 7-segment displays, plus the 7447 BCD-to-7-segment decoder. General: Performance, stability, and UI improvements throughout the app. ## Apps similar to Singular | App | Rating | Price | Category | | --- | --- | --- | --- | | [LogicGate: Circuit Simulator](https://appshunter.io/ios/app/logicgate-circuit-simulator/id6760141077) | 1.0 (1) | Free | Education | | [Circuit Simulator - VoltSim](https://appshunter.io/ios/app/circuit-simulator-voltsim/id6736870364) | 4.8 (71) | Free | Education | | [CloudLabs Electric Circuits](https://appshunter.io/ios/app/cloudlabs-electric-circuits/id1633811769) | — | Free | Education | | [Electro Sim](https://appshunter.io/ios/app/electro-sim/id6758049588) | — | Free | Education | | [CircuitWay - Circuit Simulator](https://appshunter.io/ios/app/circuitway-circuit-simulator/id6751744974) | 5.0 (1) | Free | Education | | [Smart Logic Simulator](https://appshunter.io/ios/app/smart-logic-simulator/id6742043778) | 3.0 (2) | Free | Education | ## More apps by Ali Mert TUFEKCI - [FL Lotto Results](https://appshunter.io/ios/app/fl-lotto-results/id1483311310) - [Logic Circuit Simulator](https://appshunter.io/ios/app/logic-circuit-simulator/id1554116346) - [IL Lotto Results](https://appshunter.io/ios/app/il-lotto-results/id1558071553) - [Dmv Practice Test For Florida](https://appshunter.io/ios/app/dmv-practice-test-for-florida/id1628495628) - [GA Lotto Results](https://appshunter.io/ios/app/ga-lotto-results/id1631544859) - [Mr 10m](https://appshunter.io/ios/app/mr-10m/id1643924499) All apps by Ali Mert TUFEKCI: https://appshunter.io/developer/1483311309 ## Related topics [circuit simulator q](https://appshunter.io/ios/topics/circuit-simulator-q) · [multimeter simulator](https://appshunter.io/ios/topics/multimeter-simulator) · [circuit simulator](https://appshunter.io/ios/topics/circuit-simulator) · [circuit simulator electrical](https://appshunter.io/ios/topics/circuit-simulator-electrical) · [logic circuit simulator pro](https://appshunter.io/ios/topics/logic-circuit-simulator-pro) · [mask design simulator](https://appshunter.io/ios/topics/mask-design-simulator) · [proto circuit simulator](https://appshunter.io/ios/topics/proto-circuit-simulator) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
