Retention
How to read a retention curve without lying to yourself
A retention curve is a sentence with a number attached. Most Friday packs invert that: they show the number and hope the sentence arrives in the meeting. It rarely does. The CPO asks why D7 moved, someone mentions “seasonality,” and the room moves on. That is not reporting. That is weather.
At the Bangkok desk we ask participants to write the caption before they paste the chart. If you cannot finish the caption, you do not understand the curve yet. The chart is not the work.
D1 and D7 are not personalities
D1 on a grocery app in Chiang Mai is not the same object as D1 on a late-night entertainment surface in Bangkok. One is “did the household try to place a second basket after a failed PromptPay.” The other is “did the rider open the app after 22:00 without a promo.” Collapsing both into a single D1 line is how imported templates quietly insult the product.
When a desk insists on one company-wide D7, we still allow it — in the appendix. The body of the memo gets the audience-specific return window. Weekday office riders often need a five-day window that ignores Sunday. Festival weeks need a note, not a footnote buried under a logo.
Calendar before commentary
Songkran, Chinese New Year in some districts, payday Thursdays, a sudden KYC prompt after a regulatory letter — these move curves more honestly than most “activation experiments.” We keep a one-line calendar under every retention chart in critique lab. If the calendar is empty, someone is about to invent a product story that the ops team will not recognise.
Thai consumer apps also leak sessions into LINE Mini App surfaces. If your SDK never sees those sessions, D7 is undercounting returners who never left. Write that limitation in the body. Do not wait for counsel to ask.
A working read, in order
First: name the cohort in words a support agent would use. Second: state the return definition (open, paid, completed trip). Third: place the calendar. Fourth: show the line. Fifth: say what you will cut next week — a narrower rail, a province, a language — not a twelve-item backlog.
If D7 rose and you cannot point to a product or calendar change, say you do not know. “We do not know” is a legitimate insight sentence. It is rarer than it should be.
Retention Signal Lab spends four sessions on this order. Audience Insight Studio embeds it in module three. Neither seat will raise your D30. They will stop you leading the standup with a lonely percentage.
