Do I need a coach to make sense of an AceSense report?

No. The report is written for an NTRP 3.0–4.5 player. It tells you which shot type is leaking points, where on the court you're missing, and the one technical thing to work on next session. If you do have a coach, the PDF is exactly the right artefact to send them — it shortens 'remind me what we worked on' from 10 minutes to 30 seconds.

How often should I record?

Once a week is the sweet spot. More than that and you'll start chasing noise — match-to-match variance for a club player is huge. Less than once every two weeks and you'll lose the thread between reports. Pick one league night and make that your recording night.

Will it work on my home club's court? It's not a fancy facility.

Yes — that's specifically the point. AceSense was built for public-park and club-level courts, not stadiums. As long as the court has visible lines and your phone can see most of the playing area from behind the baseline, you're fine. Clay, hard, and indoor hard work. Heavily worn or partially-snow-covered courts can break court detection — see /accuracy for the full picture.

Can I use it for doubles?

Singles is the supported path today. Doubles works for shot detection and stroke quality on whichever player you're tracking, but the court heatmap is calibrated to a singles court layout, so the bounce-zone breakdown will be less useful in doubles. Use AceSense for your singles league nights, not your Saturday social doubles.

What if I'm not actually NTRP 3.0–4.5? I'm a 4.5+ or a 2.5.

If you're 4.5+, you'll still get use out of the report, but the coaching tips are calibrated to common 3.0–4.5 leak patterns — they may feel obvious. If you're below 3.0, the technical tips can be more than you need; the simpler 'film, watch, copy a pro on YouTube' loop may serve you better for a year before AceSense earns its keep.

AceSense for Club Players: The Once-a-Week Diagnostic

If you play league tennis once or twice a week at NTRP 3.0–4.5, here's how to use AceSense to fix what's actually leaking points — without a coach.

You play tennis once or twice a week. You're somewhere between NTRP 3.0 and 4.5 — comfortable rallying, working on a second serve you can trust, and you have a clear sense that something is leaking points but you can't tell what. Maybe your group lessons are €60 each and you do one a month. Maybe you don't have a coach at all. Either way, the gap between playing tennis and improving at tennis is wider than it should be, and most of it is information.

That's the gap AceSense was built to close. This page is how to use it well if you're a club player.

The honest framing

Watching a recording of yourself play is one of the highest-leverage things a club player can do — but only if you know what to look at. There's a popular Quora question that asks exactly this, and the answers are more honest than most: yes, it works, but only if you have something to point at. Otherwise you're a person watching themselves move and concluding "I look weird."

AceSense's job is to point at things. The pipeline turns a 60-minute match video into a per-shot breakdown — every forehand, every backhand, every serve, with where it bounced, how clean the contact was, and what the report-level pattern looks like. You don't have to know what to look for. The report tells you what to look at.

The weekly workflow

Here's the loop we recommend. It takes about 15 minutes of setup and review per week.

1. Pick one match a week to record

Don't record everything. The temptation is real — especially after the first time you see your own forehand on video — but recording every hit creates a backlog you'll never review, and a Reddit thread on r/10s about whether SwingVision users record everything shows the same pattern: the people who get value out of video review pick one regular slot.

Make it your league night, your standing Tuesday hit, or your Sunday club ladder. Same court, same opponent tier, same time of day. That keeps the comparison clean from week to week.

2. Set up the phone before the warm-up

You need the phone behind the baseline, roughly net-tape-height to a foot above (3 to 4 feet / 1m to 1.2m), centred on the court. A €15 fence mount or a tripod with a phone clip both work. The full setup guide is at /how-to/film-your-tennis-match. Two minutes before warm-up is enough — start the recording, hit the court, forget it's there.

3. Upload after, not during

When you get home (or on the drive, in the passenger seat), open AceSense and upload. The pipeline takes minutes — TrackNet finds the ball, court detection locks the keypoints, MediaPipe does pose, the bounce/shot classifier marks every event. By the time you've made dinner, the report is in your inbox.

4. Read the report in this order

This is the bit most players skip. Don't open the report and scroll. Read it in this order:

The court heatmap. This is the page that earns its keep for club players. It shows where your shots actually bounced, broken down by shot type. The single most common pattern at NTRP 3.5 is "I think I'm hitting cross-court forehands, but the heatmap shows half of them are bouncing in the middle third." That's a 4-week project right there.
The shot-type counts. How many forehands? How many backhands? Most club players run 3:1 forehand to backhand and don't realise it. The opponent figured it out by game three.
The stroke-quality score for your weakest shot. This is the pose-based score. It tells you, by component (preparation, contact, follow-through), where the technique is breaking down. It's the feature most club players underuse.
The PDF. Save it. Three months from now you'll want to compare.

5. Pick one thing to work on

The report will surface five things. Pick one. Not five. The single biggest mistake at this level is trying to fix three technical things at once and breaking the parts that already worked. Pick the one with the highest impact-to-difficulty ratio (the report flags this) and work on it for the next two weeks.

The feature that earns its keep for club players: the heatmap

If we had to pick one feature that pays for itself for a once-a-week club player, it's the court heatmap. The reason is simple: club players have a strong sense of their technique (which they overestimate the importance of) and a weak sense of their placement (which is what actually wins matches at this level).

The heatmap shows you, with no judgment, where your shots land. After three weeks of data, you'll see the pattern your opponents already see. The 3.5 player who thinks they have "good depth" but has a heatmap clustered six feet inside the baseline gets more value out of one image than from a year of group lessons.

What changes in 4 weeks

If you record one match a week for four weeks and follow the loop above, here's what tends to happen — based on conversations with the first 100 AceSense users at this level:

Week 1: Mild horror at how often you slice your backhand when you "thought you were rolling it." This is the calibration week.
Week 2: First real diagnostic — the leak you didn't know about. Usually placement (heatmap) or shot-mix (you're avoiding your backhand more than you realised).
Week 3: Numbers move slightly. You won't feel different on court, but the report shows the change. This is the "trust the data" week — most players quit here.
Week 4: You'll feel the change in a match. Usually it's the second-serve consistency, or the cross-court forehand percentage, that moves first.

We don't promise NTRP-level jumps in 4 weeks. Anyone who promises that is selling. We promise you'll have information — and as a club player, information is the bottleneck.

When AceSense isn't the right tool for you

Honest section. AceSense is wrong for you if:

You play less than once a fortnight. The signal-to-noise on weekly reports gets too thin. Save your money and play more.
You're 4.5+ and you have a regular coach who films you. A coach with a phone can do most of what AceSense does, faster, with the trust relationship already in place. Use AceSense as a between-lesson tool, not a replacement.
You play at a club with PlaySight or a hard-wired SmartCourt system. You already have better data than we can give you. Use that.
You hate looking at video of yourself. This is more common than people admit. If watching yourself play is going to make you stop playing, skip the tool. The point is to enjoy tennis.

Pricing for club players

The free tier covers two analysed matches a month, which is exactly the recording cadence we just described. If you record more than that, the paid tier is the right call. Full breakdown at /pricing. No annual-only billing, no Apple-Watch-required, no surprise upgrade tiers — we wrote a whole piece on how SwingVision pricing compares if you're already paying for that.

Ready to try? Record your next league night, upload it free, and we'll have your report before dinner. Or read how AceSense works under the hood first if you want to know what's actually happening to your video. Either way — the loop only works if you start it.
