Side-by-side

“Documented” means the publisher describes the feature; plan requirements are noted where the publisher states them. Swipe the table sideways on a phone.

SwingDraw: see your swing, pay once

SwingDraw (version 3.1.8) records or imports swing video, steps frame by frame, and adds three kinds of reference: an automatic clubhead path trace, on-device body tracking with spine angle and a Head Stability score, and your own lines, circles, and angles. Two saved swings can play side by side. Swings live in a library with tags, club filters, favorites, voice notes, and a tempo ratio, and export as marked photos or videos.

Better fit elsewhere if: you want the app to tell you what is wrong, you want 3D numbers, you need remote lessons, or you use Android. SwingDraw does none of those.

V1 Golf: best free starting point

V1 Golf is a long-running golf video app with a large instruction ecosystem. Its April 2026 FAQ lists importing, drawing tools, and side-by-side comparison as free. Golf+ ($9.99/month or $69.99/year on the App Store) adds the overlay tool and skeletal tracking; Advanced V1sion ($119.99/year on V1’s site) adds hand and ball trace. Paid coaching memberships connect you with V1 instructors.

Choose it over SwingDraw if you want model swings, ball trace, or remote lessons, or if the free tier already covers what you need.

OnForm: built for coaches and their students

OnForm’s current plans start with a free Individual Basic tier, then Individual Standard at $9.99/month or $99.99/year and Premium at $14.99/month or $149.99/year. Coach plans run from $19.99/month (Basic) to $59.99/month (Pro), with a 14-day trial and no card required. Athletes connected to a coach can use a free plan. It supports side-by-side and overlay comparison, voice-overs, and remote review.

Choose it if a coach reviews your video remotely, or if you coach and need a shared student library.

Sportsbox 3D Golf: numbers from one camera

Sportsbox builds a 3D model from phone video and reports measurements such as pelvis and chest turn, sway, and lift. Its free account is described by Sportsbox as mostly a demo: 5 3D sessions a month, drawing tools, 2D/3D comparison, and one goal. Paid tiers are 3D Player and 3D Pro; the App Store lists 3D Player at $15.99 and $109.99 and 3D Pro at $79.99 and $799.99 (billing periods are not labeled there).

Choose it if you want quantified body rotation data rather than a visual review.

18Birdies: GPS app with an AI swing analyzer

18Birdies is primarily a GPS, scoring, and stats app. Its AI Swing Analyzer (record or upload face-on or down-the-line) rates the swing, flags faults, and suggests drills, and it requires Premium: $19.99/month or $99.99/year with a 7-day trial, or $7.99/week.

Choose it if you already want on-course GPS and would use the swing feedback as a bonus.

Swing Profile: hands-free at the range

Swing Profile detects swings automatically, replays them in slow motion, and adds automatic plane lines and ball tracking. The free tier saves up to 3 recordings. Its website lists Elite at $8.99/month or $49.99/year (shown as discounts from $12.99 and $99.99) and Coach at $19.99/month or $99.99/year; the App Store lists several other Elite prices.

Choose it if you practice alone and want the app to capture swings without touching the phone.

GolfFix: AI that tells you what to fix

GolfFix analyzes a recorded or imported swing, detects faults, and suggests fixes and drills. The App Store lists its Advanced plan at $14.99/month or $99.99/year.

Choose it if you want direct feedback without a coach and are comfortable with an AI’s interpretation.

CoachNow: coaching across sports

CoachNow combines video analysis (skeleton tracking, drawing, side-by-side, voice-overs) with coach–athlete spaces. Analyze costs $9.99/month or $59/year; PRO is $49.99/month or $499/year, each with a 7-day trial.

Discontinued apps

Hudl Technique was acquired by OnForm in May 2021 and discontinued; support ended in October 2021. Coach’s Eye by TechSmith was retired in 2021–2022. A new, unrelated app named “Coach’s Eye” by Gym Art Inc. launched in March 2026. See the Coach’s Eye alternative guide.

How to choose in five minutes

1. Name the job: see it, fix it, measure it, or share it with a coach.
2. Take one real swing video and try the exact workflow you will repeat.
3. Check which plan that workflow requires; a free download is not free access.
4. Check where your video goes: on device, or into an account in the cloud.
5. Add up a year (or three) of the plan you need.
