AceSense vs SwingVision: 2026 honest comparison
Side-by-side of features, accuracy, price, and Android support. For SwingVision players doing due diligence — and for everyone still on Android.
If you're already on SwingVision and it works for you, this page tells you when AceSense is worth a look — and when it isn't. If you're on Android, the answer is shorter: SwingVision still doesn't run on your phone, and AceSense does.
We're not here to bash a competitor. SwingVision is the most polished iOS tennis-analysis app on the market, and the team built a category. But there are three places it loses people consistently: Android exclusion, opaque pricing tiers, and accuracy complaints on serve speed and clay-court line calling. AceSense was built around those three.
TL;DR
| AceSense | SwingVision | |
|---|---|---|
| iOS | Yes | Yes |
| Android | Yes | No (iOS-only as of April 2026, source) |
| Apple Watch required | No | Required for real-time line calling |
| Free tier | Yes — full per-shot report on short videos | Limited free tier |
| Entry paid tier | €19/mo Pro | $14.99/mo Plus (source) |
| Top tier | €49/mo Team | $39.99/mo Max (source) |
| Annual top tier | Pro €19/mo annual | $400/yr at top tier (Tennisnerd) |
| Hosted in EU | Yes — europe-west1 | US-hosted |
| Published accuracy methodology | Yes — /accuracy page | No |
| Hardware required | Phone only | Phone + Apple Watch (recommended) |
| Paddle sport mode | No (tennis only) | Yes |
| Clay-court detection | Yes | Mixed — App Store reviews report failures |
When SwingVision is the right choice
This section is non-negotiable. If you're in any of these buckets, stop reading and use SwingVision:
- You're on iOS, you have an Apple Watch, and you want real-time line calling during your match. That workflow is SwingVision's signature feature and AceSense doesn't replicate it. AceSense does its line-related work post-recording, against the video. If you want the umpire-on-your-wrist experience, SwingVision is the one.
- You play the smaller paddle sport. SwingVision supports it as a first-class sport; AceSense does not.
- You want a mature, large-community product. SwingVision has been live since ~2019, has thousands of App Store reviews, an established Discord, and a long bug-fix history. AceSense is younger.
- You record in 4K and want the highest line-call accuracy SwingVision offers. That's the Max tier ($39.99/mo, ≈$400/yr). It is genuinely better than their lower tiers for pure line-call work.
- Your circle is on SwingVision. If your hitting partners and coach already share SwingVision report links, the network effect matters.
If none of those describe you — keep reading.
When AceSense is the right choice
The differentiation comes from four wedges:
1. You're on Android
SwingVision has been iOS-only since launch. The team has publicly acknowledged Android demand on its Android update page; a private alpha has been mentioned; no public release exists as of April 2026. The forums are full of the same question:
- "Will SwingVision still work with an Android?" — Talk Tennis thread
- "Genuinely thinking of getting a iPhone just for the swing[vision]" — r/10s thread
If you're on a Pixel, Samsung, or OnePlus, AceSense is the answer. Same shot detection, same court keypoints, same per-shot report. We didn't bolt Android on — we built mobile-first for both stores.
2. EU-friendly, transparent pricing
SwingVision runs three tiers — Plus at $14.99/mo, Pro at $24.99/mo, Max at $39.99/mo (SourceForge listing). Annual Plus is $95.99 (same source). The Tennisnerd review puts it bluntly: "the $150/year plan gets you HD recording, but 4K and more accurate line calling require paying $400 annually" (Tennisnerd).
AceSense pricing:
- Free — full per-shot report on short videos, single court.
- Pro €19/mo — unlimited videos, full match length, all features.
- Team €49/mo — multi-coach seats, async review workflow.
EU pricing is in EUR, billed in EUR, hosted in europe-west1. No surprise paywalls between tiers, no "the feature you want is one tier higher than the one you bought."
3. Published accuracy methodology
This is the wedge no other tennis-AI vendor competes on. AceSense maintains a public regression suite — compare_events.py — that scores shot/bounce/event detection against hand-annotated ground truth. The numbers, the test set composition, the failure modes, and the per-shot-type F1 are all on /accuracy.
Why does this matter? Because the loudest SwingVision complaints are accuracy complaints:
- "The advertised 'AI scoring' is never correct" — App Store reviews
- "on clay it doesn't understand where the lines of the court are" — App Store reviews
- "Is this swing vision MPH accurate, my hardest serve only 66 mph?" — r/10s
When a vendor doesn't publish a methodology, you have to take their word for the marketing number. We'd rather you take the test set.
4. No hardware lock-in
SwingVision's full line-call workflow assumes an Apple Watch. AceSense doesn't. If you don't own a watch, don't want to buy one, or don't want to wear one, AceSense gives you the same per-shot output from a tripod-mounted phone.

| Stroke quality scoring | Yes — pose-based per-component | Limited — basic technique flags |

Pricing in plain English
SwingVision (SourceForge listing, Tennisnerd review):
- Plus — $14.99/mo or $95.99/yr (≈$8/mo annualised). HD recording, basic shot detection.
- Pro — $24.99/mo. More features, more cloud storage.
- Max — $39.99/mo (≈$400/yr). 4K capture, top-tier line-call accuracy.
The Tennisnerd quote is worth re-reading: "the $150/year plan gets you HD recording, but 4K and more accurate line calling require paying $400 annually." In other words, the feature you probably want is not on the tier you'd reasonably start at.
AceSense:
- Free — full per-shot report on short videos, no credit card.
- Pro — €19/mo. Unlimited match length, full feature set.
- Team — €49/mo. Multi-coach, async review workflow.
No 4K paywall. Same shot-detection accuracy on every tier. EU billing, EU hosting.
What real users complain about
Buying decisions live or die on the negative reviews. Here are the verifiable ones:
SwingVision — accuracy:
"The advertised 'AI scoring' is never correct." — App Store reviews
SwingVision — clay courts:
"on clay it doesn't understand where the lines of the court are." — App Store reviews
SwingVision — pricing tiers:
"the $150/year plan gets you HD recording, but 4K and more accurate line calling require paying $400 annually." — Tennisnerd review
SwingVision — Android:
"Will Swingvision still work with an Android?" — Talk Tennis thread
"Genuinely thinking of getting a iPhone just for the swing[vision]" — r/10s thread
SwingVision — serve speed plausibility:
"Is this swing vision MPH accurate, my hardest serve only 66 mph?" — r/10s
"How accurate is Swingvision? Am I really serving 130mph?" — r/10s
We address each of these on /accuracy with a published number, a test-set description, and a known-failure section.
How to switch from SwingVision to AceSense
Three steps:
- Export your existing SwingVision videos. They live in your Photos library if you record in-app — open the SwingVision match, tap share, save video. You don't lose anything; SwingVision keeps your account.
- Sign up for AceSense free at acesense.io on iOS or Android. No card.
- Upload one match. Same camera angle works (back-of-court, head-height, full court visible). The AceSense report drops into your inbox in a few minutes.
Run both reports side-by-side on the same match. That's the comparison that actually matters — your video, both apps, real numbers. If SwingVision wins on your data, stay. If AceSense wins, switch.
When you should use both
A non-trivial number of players keep both. Reasonable workflow:
- SwingVision for live match days when you have your Apple Watch and want real-time calls.
- AceSense for everything else — Android phone matches, practice video, async coach review, deep stroke-quality work, anything on clay.
This isn't a "us vs them" — it's a "what does this video need." If you have iOS + watch + a hard court, both work. If any of those is missing, AceSense is the practical answer.

Frequently asked questions
- Is SwingVision available on Android?
- No. As of April 2026, SwingVision is iOS-only. The team has acknowledged Android demand publicly on its newsletter page and confirmed a private alpha, but there is no public release. Rec players have been asking since 2019.
- Does AceSense need an Apple Watch?
- No. AceSense runs entirely from your phone video. No watch, no proprietary sensor, no fence camera. SwingVision uses an Apple Watch for its real-time line-call workflow; AceSense does the equivalent work post-recording, on the video itself.
- Is SwingVision worth 400 dollars a year?
- It depends what you actually use. SwingVision's $39.99/mo Max tier (≈$480/yr) unlocks 4K capture and the most accurate line calling. If you only want shot detection, stats, and heatmaps, the $14.99/mo Plus tier (or AceSense's free tier) covers it. The 400-dollar question only really matters for serious match-recording use.
- How accurate is SwingVision compared to AceSense?
- Both apps publish marketing claims; only one publishes a methodology. AceSense maintains a public regression suite (compare_events.py) that scores shot/bounce events against hand-annotated ground truth. SwingVision App Store reviews specifically complain about clay-court line calling and 'AI scoring' that 'is never correct.' We link the receipts below.
- Will my SwingVision videos work in AceSense?
- Yes. AceSense accepts any phone-recorded MP4 — front-of-court, back-of-court, single camera. If you have an existing SwingVision video library, you can re-process those same files in AceSense and compare reports side-by-side.
- Does AceSense support doubles?
- Doubles is supported with a known caveat: the player-detection model occasionally swaps net partners on long crosscourt rallies. We document this in /accuracy. SwingVision's doubles support is more mature.
