A stopwatch that records every lap and split to 1/100 of a second — and keeps the whole run after you stop. Most stopwatches throw the run away the moment you reset. This one anchors timing to the system wall clock so it never drifts, flags your fastest and slowest lap the instant you record them, saves the run to History, and scores how even your pacing was on a 0-100 consistency scale. Laps, splits, charts and totals — not just a number that disappears. WHAT YOU GET - Lap time and split time read to the hundredth, newest lap always on top - Your fastest and slowest lap flagged automatically while you are still timing - A 0-100 consistency score that tells you whether your pace held or drifted - Saved runs with lap charts, pace-variation graphs and best / average / worst breakdowns - Two saved runs placed side by side, lap by lap, with the gap shown on every row - Lifetime totals: runs timed, laps recorded, time tracked, best lap ever PERFECT FOR - Runners timing track laps, tempo runs and interval reps - Lifters and HIIT athletes marking rounds and keeping rest honest - Coaches timing repeats and comparing one athlete's runs week to week - Anyone timing brews, bakes, lab reactions or focused study blocks WHY NOT JUST USE THE BUILT-IN CLOCK APP? Because it forgets. The stock stopwatch shows a lap list that vanishes the second you reset — no saved runs, no chart, no side-by-side comparison, no export. Here every run is kept, labelled with a preset (Sports, Cooking, Study), grouped by day, and ready to reopen months later. Tap Lap and the clock keeps running; the screen stays lit so you never lose your read mid-run. PRIVACY Every run is stored on your device only. No account, no sign-in, no ads, no third-party tracking. Works fully offline, in airplane mode, anywhere. FULL ACCESS Full access unlocks unlimited saved runs, per-run lap charts, the best / average / worst breakdown, run-vs-run comparison, and CSV export of any session you have timed. Choose a weekly plan, a yearly plan, or a one-time lifetime unlock — the lifetime option is a single payment with nothing to renew. Tap Start, tap Lap at every checkpoint, then save the run and watch your consistency score climb.

Verdict

The call

The clearest difference is ads: Stopwatch at none against 20s Timer's shown. Stopwatch also leads on update cadence (every 4 weeks vs every 37 months). 20s Timer's advantage is iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
