My two fitness apps share a buyer, not a workout. So I paired them.

Quick follow-up to my For Time post. I run a small portfolio of pay-once Apple apps, and two of them are fitness apps: WODrounds (interval timer for CrossFit and HIIT, $2.99) and Anvil Workout (strength log, $2.99).

I pulled the numbers this week to decide where to spend marketing effort, and the interesting part was about the pair:

WODrounds is my revenue leader (about $170 gross since March). Steady, but site traffic dipped 15% last month. Anvil is my momentum leader: two thirds of its lifetime downloads landed in the last 30 days and its site traffic grew 59%. A big chunk of that came from this community, so thanks.

My first instinct was "same audience, cross-sell hard". Looking closer, that is wrong. A 5/3/1 lifter logging sets does not want a WOD timer, and a CrossFitter mid-metcon does not want a barbell log open. What the two apps share is not the workout, it is the buyer: someone in the Apple ecosystem who would rather own a small focused tool than rent a platform.

The overlap is also asymmetric. CrossFit already includes barbell work, so a WODrounds user plausibly wants a strength log. The reverse is much weaker.

So instead of merging the marketing, I paired them: each site now points to the other in one honest sentence ("log your lifting there, time your conditioning here"), and I will let App Store source data tell me whether trust actually transfers between the two.

I promised a pay-once numbers retrospective in the For Time post. Still coming this fall, with before/after data. Curious if anyone else runs sibling products and has seen maker-trust carry a buyer from one to the other?
