SkillScan vs Calis AI: two ways to scan a planche
Both apps scan a planche from your phone. They measure different things, charge in different ways and treat your video differently. A side-by-side from the person who builds one of them, with every claim about the other sourced.
Short answer
Calis AI is a subscription app for three skills (planche, handstand and muscle-up) that gives AI-written form feedback, a coach you can chat with and structured progressions. Scanning needs a subscription, from $9.99 a month or $39.99 a year. SkillScan does only the planche, measures seconds held and seconds clean against the FIG gymnastics Code of Points, and scans for free every session; its paid part is a training plan. Pick Calis AI if you want feedback on all three skills and a chat coach. Pick SkillScan if you want a measured number against a written standard without paying to scan.

What each one measures
SkillScan answers one question: how much of your hold would count under the gymnastics code. It tracks your joints through the clip and times two things. Seconds held is how long you were in a recognizable planche. Seconds clean is how much of that time your elbows stayed within 15° of straight and your body within 20° of horizontal, the smallest deduction band in the code FIG MAG CoP 2025-2028 · Art. 9.2.8, 9.2.9. The fault that cost the difference (elbows, body line or hips) and the frame where it happened come with the numbers.
Calis AI gives you a written breakdown of your form, what's working and what to improve, for three skills. Its privacy policy says pose detection runs on your phone and a few still frames are sent to large AI models, named as GPT-4.1 and Claude Sonnet, which write the feedback. Its listing describes logging your hold times yourself, so I couldn't confirm that it times the hold from the video. It doesn't name a standard the feedback is judged against.
The practical difference: SkillScan gives you a number you can compare week to week, measured the same way every time. Calis AI gives you advice in words, about more skills, from models that see a handful of frames.
Price
Calis AI's listing says every feature, scanning included, needs an active subscription. The App Store lists two tiers. The regular plan is $9.99 a month or $39.99 a year. "Unlimited" is $5.99 a week, $12.99 a month or $59.99 a year. There's also a $29.99 special offer.
SkillScan's scans are free every session, with both numbers, the break frame, the replay and the share video. The paid part is the Next Tier Plan, weekly training sessions dosed from your own measured hold and re-planned after each scan, plus your full history. It's $89.99 a year or $9.99 a month, $39.99 a year for the first 100 members, and the annual plan starts with a free week.
If you only want to know where your planche stands, SkillScan costs nothing. If you want a paid plan, the lowest annual price is $39.99 on both, though SkillScan's is a founding price for its first 100 members and its list price is $89.99.
What happens to your video
This is where the two apps made opposite choices, and neither is free of trade-offs.
Calis AI keeps your regular scan videos on your phone, according to its privacy policy, and sends only 2 to 4 low-resolution frames per scan to AI providers through OpenRouter. When a scan sets a personal best, the full clip and a thumbnail are uploaded to a public leaderboard, where the policy says anyone who taps the entry can play it. If you signed in with Apple or Google, your name is shown. Its App Store privacy label, which the developer fills in, lists photos or videos among the data linked to you that may be used for third-party advertising.
SkillScan uploads your clip to its own server in Paris, measures it there and deletes it straight after, whether the measurement worked or not. The video isn't sent to Google or any AI company. What stays in your history is the skeleton: joint positions over time, which can't be turned back into footage. When you ask for a training plan, your numbers (not your video) are sent to Anthropic's Claude to write it. SkillScan's own label lists photos or videos as linked to you for app functionality, because the clip does leave your phone for the few seconds it takes to measure.
Which one to pick
If you're training the handstand and muscle-up alongside the planche and you like asking questions in a chat, Calis AI covers more ground in one subscription.
If the planche is the skill you care about, and your question is whether your hold counts or why it's stuck, SkillScan answers it with a measurement, and you can scan as often as you train without paying.
You can also try both. SkillScan's scans are free; Calis AI's subscription can be cancelled from your App Store account settings.
