For accuracy numbers per release, see the accuracy methodology page.

2026-04-25 — EU pricing & expanded clay benchmark

The release this site went live with.

  • Native EUR pricing rolled out. Free, €19/mo Pro, €49/mo Team. Annual options at ~2 months free.
  • VAT handling at checkout for EU customers (private and business with VAT-reverse-charge).
  • Clay test set expanded by 8 hours of new red-clay footage from EU beta players. Bounce localisation median error on clay improved from ~45 cm (previous build) to ~38 cm in the regression suite.
  • Coach share links now have configurable expiry (Pro). Default remains 30 days.
  • Per-shot CSV export added on Pro for the per-shot timeline.

2026-04-10 — EU launch & marketing site

  • acesense.io marketing site went live with full content surface (/how-it-works, /accuracy, /pricing, /faq, comparison and alternative pages).
  • EU-region pricing announced ahead of full rollout (rolled out 2026-04-25).
  • GDPR data export and deletion moved from email-request workflow to one-tap in the dashboard.
  • europe-west1 confirmed as sole region for video and report storage. No data leaves the EU at any point in the pipeline.

2026-02-10 — Doubles support (beta)

The single most-requested feature from the first year of beta.

  • Doubles match support in beta. Aggregate shot mix, court heatmap, and ball tracking work in doubles. Per-player attribution on net exchanges remains unreliable in this release; documented on the accuracy page.
  • Doubles-specific court detection for the doubles tramlines (now included as keypoints when a doubles match is uploaded).
  • In-app warning when an uploaded match is detected as doubles, pointing the user to the current beta limitations.

2025-12-15 — Court detection on clay

  • Clay-specific court keypoint model rolled out to GA. Detection accuracy on red clay climbed from ~93% (previous model trained on hard courts only) to ~97%.
  • Indoor court keypoint accuracy improvements via expanded indoor training set (+12 hours from EU clubs).
  • Wide-angle phone-lens warning at upload — if the system detects ultrawide footage with significant barrel distortion, the user is warned and offered the option to re-upload from the main lens.

2025-09-04 — Stroke quality v2

  • Stroke-quality scoring v2 launched. Re-trained on a larger reference distribution (~50 coach-demonstration sessions plus high-scoring amateur play). Forehand and backhand F1 each climbed by ~0.04 in the regression suite.
  • Per-component score breakdown added to the report — trunk rotation, contact-point variance, racquet acceleration, follow-through completeness, scored independently with the lowest-scoring component highlighted as the suggested fix.
  • Top three things to work on auto-summary added to the report cover page.

2025-06-10 — Android launch

The wedge against SwingVision goes public.

  • Android app released to the Google Play Store. Built from the same Flutter codebase as iOS; shipped to GA after 8 weeks of internal testing on Pixel 6/7/8 and Samsung Galaxy S22/S23.
  • Initial public accuracy benchmark published. First version of what is now the accuracy page.
  • Beta-tester programme expanded to 50 players across the EU.

2025-04-22 — iOS app launch (beta)

  • iOS app released to TestFlight for beta players. iPhone 11 and later, iOS 16+.
  • TrackNet ball detection, court keypoint detection, FasterRCNN player detection, MediaPipe pose, and CatBoost shot classification all integrated into a single processing pipeline running on RunPod serverless GPUs.
  • Coach-share links in initial form (no expiry control yet — added in 2026-04-25).

2025-03-12 — First closed beta

How it started.

  • Closed alpha with the first 10 beta players. Hard courts only, singles only, no clay or indoor support.
  • First end-to-end run of the full pipeline against a real amateur match (sample_match_1min_720p.mp4 — still in our regression suite today).
  • acesense-annotate desktop labelling tool first used internally for ground-truth data collection.
  • NVIDIA Inception membership confirmed.
