Every account starts with a few free Ronnie voice minutes so you can try it. Pro members get a large monthly pool of minutes for live voice coaching. One minute of coaching uses one minute.

You can try your first workout free, with no credit card. Pro is $19.99 a month, which is less than a dollar a day, and you can cancel anytime. You manage your plan right from your account.

The main product experience today is the web app. There is mobile work in progress, but the supported, user-facing flow is still browser-first.

An AI rep counter uses computer vision to track your body's key joints (a pose-estimation model maps points like hips, knees, shoulders, and elbows) and watches how those joints move through each repetition. When the movement completes a full range-of-motion cycle, it counts one clean rep. Spotter runs this model on your own device, so it can count reps from a phone or webcam without any wearable, clicker, or sensor.

Yes. The most common reason form breaks down when you train alone is that no one is watching for shortened range of motion, changing tempo, or inconsistent reps as you fatigue. Spotter acts like a second set of eyes: it measures the movement you actually performed and flags rep-quality drift, so you can self-correct without hiring a coach for every session.

The most frequent problems lifters face are partial reps (cutting depth or range, especially near failure), inconsistent tempo, ego lifting with too much weight, and losing count during heavy sets. Spotter makes these visible by measuring range of motion, tempo, and completed reps rep-by-rep, so you can fix the pattern instead of guessing later.

Plateaus usually come from one of three things: inconsistent training stimulus, hidden form drift that reduces real working range, or no objective record to progressively overload from. Spotter helps with the last two by counting honest reps and tracking rep quality over time, so you can apply progressive overload to numbers you can trust instead of feel alone.

Full range of motion generally drives more muscle growth and strength per rep than partial reps, and it builds joint control. The catch is that range quietly shrinks as you fatigue, so the reps that feel hardest are often the shortest. Spotter watches top and bottom positions on each rep so you can keep range honest across a whole set.

Yes, you can try your first workout free with no credit card. Rep counting and form feedback for supported lifts run right in your browser, and every account includes a few free voice-coaching minutes. Pro unlocks the full experience: live coaching, video grading, saved workouts, and more voice minutes.

Spotter supports common strength movements including squats and squat variations, bench and incline press, overhead press, deadlifts and Romanian deadlifts, barbell rows, lat pulldowns, pull-ups and chin-ups, push-ups, curls, and related bodyweight and free-weight lifts. Pick the closest supported movement and Spotter applies the right rep and range rules.
