LaneSlate
Run a clear shared-clock time trial with touch-ready lane controls and verified history in one USD 0.99 paid download — no account, ads, analytics, subscription, or required internet connection.
LaneSlate
Time one to eight swimming lanes from one shared start, capture splits and finishes independently, and preserve every correction in a private local ledger.
One clock stays fair across every lane
Start all lanes together, then record each split and finish against the same monotonic clock with large controls built for a wet pool deck.
Touch review
Review recorded swim touches across lanes. Choose a reference lane and compare cumulative times at matching valid touch numbers. Inspect segment times, void an accidental tap with a reason, and restore it later. Original times and correction history remain intact while subsequent valid touches are renumbered. Missing touches are never interpolated, finishes are not inferred, and no rankings or training advice are generated. Share the current comparison through the system sheet. Timing and review data stay on your device.
Private records remain portable
Review objective summaries, export text or CSV, and create checksum-verified backups only when you choose.
