## AlterMe

AlterMe starts with a DNA test that maps genetic markers linked to how your body responds to exercise, nutrition and recovery. That genetic blueprint is then combined with continuous biometric signals — activity, sleep and readiness data — to produce a plan you actually follow, rather than a generic template.

The system delivers one unified plan across four pillars: fitness, nutrition, sleep and recovery. Plans are built and refreshed every week based on your goals (weight loss, strength, longevity or thriving on GLP-1 medications) and your recent data, so the guidance adapts as your body and habits change.

The company markets itself on outcomes rather than features, citing member surveys around weight loss, fitness gains and visceral fat reduction, and positions the product as HSA/FSA eligible. AlterMe is designed for people who have tried generic programs and want a plan grounded in their own biology.

**Pricing & Plans:** Paid. Entry point from $49 to start, with financing options available, plus a DNA test that is regularly discounted from around $99.

- **DNA Blueprint:** A saliva DNA test maps genetics related to fitness response, nutrition and recovery, producing an actionable blueprint rather than a raw report.
- **Biometric tracking:** Connects wearable sensor data to track activity, sleep and daily readiness, feeding those signals back into your weekly plan.
- **Adaptive weekly plan:** Your exercise, nutrition and recovery plan is rebuilt each week from your goals and latest biometric data so it never goes stale.
- **Multi-goal programs:** Choose a focus such as losing weight, building strength, increasing longevity or supporting GLP-1 treatment, and the plan adjusts accordingly.
- **All-in-one wellness system:** Fitness, nutrition, sleep and recovery live in a single app instead of being spread across multiple subscriptions and programs.

**Strengths:** Personalization driven by DNA plus live biometric data, not a static questionnaire; A single system covering fitness, nutrition, sleep and recovery; HSA/FSA eligible and priced to start at a low entry point; Weekly plan refresh keeps guidance relevant as goals change

**Limitations:** Requires completing a DNA test before the full system kicks in; Some outcome statistics come from member surveys rather than independent trials; Ongoing subscription plus test cost adds up over a year

## PureStrength (FormCheck AI)

PureStrength, now listed on the App Store as FormCheck AI, is a video-based AI personal trainer for the big three powerlifting movements. You record a working set on your iPhone, the app tracks the barbell and key joint positions frame by frame, and it returns plain-language coaching cues on what went right and what needs fixing. Because the models run on the device, your clips are processed locally rather than uploaded to a server.

The strongest part of the app is the depth of its per-lift feedback. For the deadlift it watches shoulder positioning, hip drive and lockout; for the squat it monitors depth, alignment and left/right balance; for the bench press it looks at bar path, control, grip and elbow position. Later releases extended this to bent-over rows and bicep curls, and added on-device 3D rendering so you can rotate a lift and inspect the trajectory of the bar.

The app comes from Purestrength Limited, a small studio that also publishes Larry AI, Deepbarbell and Qutie. It sits firmly in the strength-training niche rather than general fitness: if you compete in powerlifting or take your squat, bench and deadlift seriously, the specific cues are genuinely useful, while anyone looking for a full workout log or calorie tracker will want something broader.

**Pricing & Plans:** Free to download and use as of version 3.0 (January 2025), with optional in-app purchases. The app was previously subscription-based; verify the current pricing and any in-app offers on the App Store page for your region.

- **Deadlift form correction:** Track hip movement, shoulder position and lockout so you avoid a rounded back and get a clean pull.
- **Squat form analysis:** Depth monitoring plus alignment and balance alerts so you activate the right muscles on every rep.
- **Bench press guidance:** Feedback on bar path, control, grip and elbow position across the press.
- **On-device 3D analysis:** In-app 3D rendering and slow-motion playback let you replay each rep and see exactly where technique breaks down.
- **Form library and content:** Articles and videos on lifting technique, nutrition and recovery sit alongside a library of sample lifts.

**Strengths:** Detailed, lift-specific cues for squat, bench press and deadlift rather than generic rep counting.; On-device processing keeps training videos private and works without a constant connection.; 3D rendering and slow-motion replay make it easy to see exactly where form breaks down.; Became free to use in 2025, removing the previous subscription barrier.

**Limitations:** Focused on only three lifts (squat, bench press, deadlift), so it is not a general-purpose workout tracker.; Analysis quality depends on how well you frame and film your set; poor angles produce weaker feedback.; Larger download (~495 MB) because the computer-vision models run on the device.; iOS/visionOS only — no Android or web version.
