Spotter vs StrongLifts 5×5
Both run the classic full-body 5×5: squat, bench, row, press, deadlift, adding weight every session you complete your reps. The difference is what counts as 'complete.' StrongLifts trusts your taps. Spotter watches the set — it counts and scores every squat rep on depth and tempo from the camera, speaks the coaching between sets, and only progresses the weight when the reps were actually there, at depth.
Where StrongLifts is great — honestly
StrongLifts popularized the simplest effective barbell progression in the world and its app is a polished logger: timers, plate math, clean history. If you already squat with solid depth and just want to track, it's excellent and cheaper. This comparison is honest because we run the same underlying method.
The gap: a logger can't see you
The 5×5 method has one failure mode every coach knows: as weight climbs, depth quietly shrinks. You keep 'completing' 5×5 in the app while the squats get higher and higher — the log says progress, the lift says otherwise. Research backs why that matters: deeper squats drove greater quad and glute growth than partials in controlled trials (Bloomquist 2013; Kubo 2019), and strength is specific to the trained range.
Spotter closes that loop. Every squat rep is scored on depth and tempo live from the camera. If the reps were there but the depth wasn't, the weight holds — so the number on the bar stays honest.

Answers
Is Spotter based on StrongLifts 5×5?
Spotter's full-body program follows the same classic 5×5 linear progression (squat/bench/row/press/deadlift, +2.5 kg per completed session). The difference is enforcement: Spotter scores your squat reps from the camera and gates progression on real depth.
Should I switch from StrongLifts to Spotter?
If you're confident in your depth and just want a log, StrongLifts is enough. If you train alone and want the reps watched — scored depth, spoken coaching, honest progression — that's what Spotter adds.
Does Spotter work for programs other than 5×5?
Yes — squat-focused strength (linear and Texas Method), hypertrophy (upper/lower split and a leg-builder), technique and habit-building programs, all with the same camera scoring and auto-progression.
