Teardowns
Short product teardowns. One product, one decision the team made, and what I would test next.
- HevyMy favourite product
Hevy is basic, and that’s why it’s my favourite product
For a habit product, friction matters more than features. Hevy wins on the ten seconds between sets, and that is the only moment that counts.
- Splitwise
Splitwise put its paywall on the one action the product can’t work without
A shared ledger is only useful if it is complete. Splitwise's free plan limits how many expenses you can add in a day, so the limit damages the thing people came for.
- Duolingo
Duolingo’s streak doesn’t sell lessons. It sells insurance against losing them
The streak makes the daily minimum tiny and the loss feel large. The Streak Freeze then sells protection against that loss, and it only works if you buy it in advance.
