Stopa compared
Three tools that overlap with Stopa, each with a page saying what it does better than Stopa as well as what Stopa does that it does not. Figures come from each product's own site and carry the date they were read.
Where a competitor's figure has gone stale, that is an error rather than a tactic — tell us and it gets fixed.
The pages
The best-known running app on the wrist, now owned by Strava. It writes the plan for you, for $119.99 a year. Stopa does not write plans — it takes the one you already have.
The heavyweight, and the one tool here with analytics Stopa does not attempt. $134.99 a year for Premium, and it wants your plan built inside it or bought from its library.
Apple's own Workout app is free and syncs nothing. For a single repeated interval session it beats every paid tool on this page. For a sixteen-week plan it is an evening of typing.
What is actually different here
Three things, and they are the same three on every page above.
You bring the plan. Stopa does not decide what you should run. It reads the plan you already have — a coach's Excel, a published PDF, a block you built with ChatGPT or Claude — and turns it into structured workouts your watch can run. Nothing else in this bracket imports a plan from outside itself; they generate one, or they ask you to build it in their editor a workout at a time.
One plan, every watch you own. Stopa pushes to Apple Watch and Suunto directly, and one tap to connect intervals.icu carries the same plan on to Garmin, COROS, Wahoo and Zwift. You are not picking an ecosystem — the plan follows whatever is on your wrist that day, and you set it up once.
It costs a third of the alternatives. $49.99 a year against $119.99 and $134.99, with fourteen days of full access and no card to start.
Where a figure is missing it says —, never zero and never a guess. That rule is also why these pages name the things the other products do better: a comparison written by the seller is worth exactly as much as its least convenient sentence.
