Set a total and a few category limits. LensReport watches what you log and sends a nudge the moment takeaway, coffee or fuel runs ahead of plan.

Open the Budget tab, tap the total, choose a cycle (daily, weekly or monthly) and add limits for the categories you care about. Save once; it repeats each cycle.
Yes. When a category passes its limit you get a notification on your phone right away, with the amount over and a suggestion for a cap.
Yes. Turn off "repeats" and the budget becomes a single allowance that never resets, useful for a trip or a project.
No. Photo and voice entries count the same as typed ones, and the AI categorises them for you.
Setting a budget is free. Three free expenses let you try the whole app; a subscription unlocks unlimited expenses.
