SolveTime is a fast, clean speedcubing timer built for real practice — no ads, no accounts, no clutter, and it works completely offline. Whether you are chasing a sub-10 3x3 or just learning to solve, SolveTime gives you everything you need to time solves the way competitions do. WCA-STYLE SCRAMBLES Get a fresh, notation-correct scramble for every solve. Supports 3x3, 2x2, 4x4, 5x5, Pyraminx and Skewb, with proper move lengths and no redundant turns. 15-SECOND INSPECTION Turn on official-style inspection with 8s and 12s cues. Go over 15 seconds and you get an automatic +2; over 17 seconds counts as a DNF — exactly like a real solve. HOLD-TO-START TIMING Press and hold, wait for green, release to go. Adjustable hold time and the option to hide the running time so you focus on the solve, not the clock. AVERAGES THAT MATTER Live ao5 and ao12, plus ao50, ao100, best single, session mean and standard deviation — all calculated with WCA trimming rules. Set +2 or DNF penalties on any solve. SESSIONS FOR EVERY EVENT Keep separate sessions per puzzle, review your full solve history with the scramble that produced each time, and delete solves you want to drop. PRIVATE BY DESIGN Every solve stays on your device. No sign-in, no tracking, no network access, and no ads — ever. TRY IT FREE, THEN OWN IT SolveTime is free to download, and every feature is open for your first 14 days of practice. When the trial wraps up, a single one-time purchase (SolveTime Unlimited) keeps the timer, your sessions and your averages going for good. No subscription, nothing to renew. Your solves stay saved either way.

Verdict
The clearest difference is in-app purchases: Panecal Scientific Calculator at none against SolveTime's 1. Panecal Scientific Calculator also leads on device support (3 vs 1) and iOS requirement (12.0 vs 17.0). SolveTime's advantage is ads (none vs shown) and update cadence (weekly vs every 2 months). On price there is nothing between them.
