How do I correct a drink?
Tap a drink in Your log to change its amount or time. Swipe the row for Edit, Swaps or Delete. A newly added drink also has Undo. Every drink counts immediately; there is no need to finish or confirm your day.
Why is homemade caffeine an estimate?
Beans and preparation vary. Espresso starts at an average of 63 mg per regular single shot, so two shots estimate 126 mg. Water adds no caffeine to an Americano. Change the estimate for your own brew or enter a known label value.
How do I add a quick-log widget?
Press and hold your iPhone Home Screen, choose Edit → Add Widget, and search for Caffeine Tally. After adding it, press and hold the widget → Edit Widget to choose a preset or one of your saved drinks with a caffeine amount.
How do I set a daily target?
Tap Set target on Today, or go to Settings → Your routine. The 400 mg adult reference is general context, not a personal recommendation or a universal safe limit. You choose and can change your target.
How do I back up or move my records?
In Settings, choose Export JSON backup and save it somewhere you trust. On another iPhone, use Import JSON backup. CSV is for reading intake in a spreadsheet; it is not a full backup. There is no automatic cloud sync, and deleting the app can lose local records.
I paid for Premium but it is locked.
Check that your iPhone uses the Apple Account that purchased the subscription, then open Settings → Restore Purchases in Caffeine Tally. Check your connection and try again if needed. Contact support if your active subscription still is not recognized.
How do I cancel or request a refund?
Manage or cancel your subscription with Apple. Canceling renewal keeps Premium available for the remaining paid period. Your logs, history and free features stay available after Premium ends. Deleting the app does not cancel a subscription.
For billing or a refund, visit Apple’s Report a Problem page. Apple handles payment and refund decisions.
How do I delete my data?
Open Settings → Delete all personal data. This removes local app records and reminders. Delete exported backup files separately wherever you saved them. To remove correspondence you sent to support, email us.
A drink’s caffeine amount looks wrong.
Email us the brand, exact product, serving size and country. A photo of the caffeine label or a manufacturer link helps. In the meantime, add a custom drink using its label value. Your previous logs keep the amount used when you logged them.
