DeepSwing vs Onform: Comparison of the best AI Golf Swing Analysis Apps

Quick decision guide

Pick DeepSwing if you want:

1. Swing Score + Dashboard to track progress and recurring issues across sessions.
2. Cross-device Live Coach mirroring (start on iPhone, monitor on iPad/Mac browser) while staying synced.
3. A dedicated Compare Swings flow with synced playback and phase jumps (Setup/Top/Impact/Finish).
4. A local-first approach (no cloud uploads as the default posture).

1. A coach-style workflow with voiceovers, drawings, messaging, and athlete organization.
2. Capture up to four angles, hands-free auto-capture, and a 4-way player.
3. 3D visualization + 12 swing metrics and skeleton tracking (with an iOS requirement for some features).
4. Automatic cloud backup to reduce device storage pressure.

Deep dive: what it feels like to use each app

1) Training philosophy and outputs

DeepSwing pushes you toward clarity and prioritization: you get a score, you get the “most urgent fix,” and you get a dashboard that makes it obvious whether you’re trending up or stuck on the same faults. That’s ideal for golfers who practice alone and want the app to behave like a structured coach.

Onform pushes you toward review, explanation, and communication: capture swings, slow them down, draw lines/angles, record a voiceover, message the athlete, and keep everything organized by tags/collections. That’s ideal for coaches and academies—or for golfers who want a lesson-style workflow even when training solo.

2) Capture and camera workflow

Onform is very capture-centric: high frame rates (up to 240fps), multiple recording modes, hands-free auto-capture, and multi-angle recording (up to four angles). This is designed to scale with lesson volume and to reduce friction during coaching sessions.

DeepSwing is practice-centric: record/import quickly, get on-device analysis, and move straight into actionable feedback and overlays—especially around Live Coach sessions where feedback and overlays are part of the experience.

3) Comparing swings (a must-have feature for serious improvement)

Both apps support comparison, but the experience differs:

1. DeepSwing’s Compare Swings focuses on sync + phase jumps (Setup/Top/Impact/Finish). That makes it easy to compare “positions” rather than hunting frame-by-frame.
2. Onform’s comparisons fit into a broader analysis studio where side-by-side and overlays can sit alongside 3D/skeleton views (depending on device/version).

If you compare swings frequently, DeepSwing’s phase-driven approach tends to feel faster; if you build and share detailed breakdowns, Onform’s studio approach tends to feel more flexible.

4) Multi-device mirroring and range setup

DeepSwing supports cross-device Live Coach mirroring: start recording on iPhone, monitor on iPad or Mac browser, and keep overlays/annotations synced. This is extremely practical when your phone is on a tripod and you want a bigger screen right next to your hitting position.

Onform also leans into multi-device workflows and includes “Mirror Cam” as a golf feature concept (using an iPad as a live down-the-line feed). It’s a different take: more like a dedicated alignment/DTL station inside a broader coaching platform.

5) 3D and skeleton tools

Onform offers 3D visualization for golf and “12 swing metrics” generated from 2D video (recorded at 120 or 240 fps), plus skeleton tracking—features that can be compelling for coaches who want a more biomechanical presentation.

DeepSwing emphasizes 3D ghost overlay, phase scoring, and overlays that translate into simpler “do this next” coaching cues. It’s typically less about producing a biomechanical report and more about producing a training decision.

Sharing, privacy, and “can I post this swing publicly?”

This is where the apps can feel fundamentally different:

1. DeepSwing is positioned as privacy-first with on-device analysis and no cloud uploads by default.
2. Onform is positioned as a secure platform with automatic cloud backup and sharing/messaging built into the product.

You also mentioned a new DeepSwing export anonymity feature (emoji/blur face) for sharing swings externally without exposing identity. If your goal is to post in communities or share clips widely, that’s a genuinely high-value addition because it removes the need for external editors.

Pricing and value

1. DeepSwing: listed as free with in-app purchases; “DeepSwing Pro” is listed at $59.99 (pricing can vary by region/taxes).
2. Onform:
3. Personal: $5/month or $49/year
4. Coach: $29/month or $299/year
5. Academy: $79/month or $799/year

A practical way to think about value:

1. If you want a single golfer’s improvement loop with scoring + cross-device live coaching, DeepSwing Pro can be very cost-effective.
2. If you’re a coach or academy, Onform’s tiers are built specifically around scaling clients, communication, and workflow.

Who should use what?

Best for solo golfers

1. DeepSwing if you want structure, measurable progress, and fast “fix priority” decisions.
2. Onform if you want a lesson-like workflow (voiceovers, markup, organized libraries) even without a coach.

Best for coaches

1. Onform if you manage multiple students, want messaging + voiceovers, and rely on multi-angle capture and a centralized platform.
2. DeepSwing if you want to supplement lessons with a score-driven practice plan and a clean “compare two swings” review during follow-ups.

Best for academies/teams

1. Onform is designed around that use case (plans, admin tools, multi-coach workflows).

FAQ

Does Onform work for golfers without a coach?

Yes—its golf workflow is designed for both coaches and individual athletes, including self-guided analysis tools.

Is DeepSwing analysis done on-device?

Yes—its core positioning is on-device analysis with no cloud uploads by default.

Which app has better swing comparison?

DeepSwing’s compare mode is especially efficient if you think in swing phases (Setup/Top/Impact/Finish). Onform’s comparisons are strongest inside a broader coaching studio, especially when paired with 3D/skeleton views.

Do I need a newer iPhone for Onform 3D/skeleton features?

Some Onform features (like skeleton tracking / 3D analysis for golf) have OS/device requirements; skeleton tracking is noted as requiring iOS 18+ in the App Store listing.
