ChronoTrend

ChronoTrend includes 7 statistical forecasting methods completely free. ChronoTrend Pro unlocks the TimesFM 2.5 and Chronos-2 AI models via a one-time purchase.

Paste a column of numbers — daily prescriptions, weekly units sold, monthly revenue — and ChronoTrend tells you what is likely to come next, and how much to trust it.

THE DATA PICKS THE WINNER No forecasting method wins everywhere, not even the newest AI models. Which one does best depends on your own numbers: how steady they are, how strong their seasons are, and how much history you have. So ChronoTrend doesn't guess. It hides the most recent part of your history, forecasts it with every method, checks the forecasts against what really happened, and ranks the methods by how close they came. The winner forecasts your future, and you see the whole ranking, not just the answer.

MORE THAN A SPREADSHEET TREND LINE An average hides the order of your numbers, and a straight trend line misses seasons and changes of pace. ChronoTrend's methods read the trend, the repeating seasons and how recent values carry forward — and because your business changes, every forecast re-runs the test on your latest data, so the ranking keeps up with your data.

HONEST RANGES Every forecast comes with a likely range, and ChronoTrend shows how often that range held on your own past. A wide range means the future is less certain, so you can plan a buffer.

PLAIN ENGLISH One button gets a result. No settings are required, and the verdict is written in words, not statistics.

PRIVATE BY DESIGN Every calculation runs on your iPhone or iPad. There is no account, no analytics and no advertising, and your figures are never sent anywhere.
