Meals + fasting records
Fasting timer and calorie tracker for iPhone—US$4.99 once.
Start a private on-device fast with a 12, 14, 16, or 18-hour reference target. Photograph meals for directional calorie and macro estimates, then review timing and intake patterns in one app.

One Today view for timing and intake
Log the meal. Run the timer. Inspect the pattern.
Food-photo estimates and fasting records answer different questions. AskFork keeps both visible without pretending either one proves a health outcome. Screens below use illustrative saved sample data.
A timer you control
Record timing without turning it into advice.
A fasting target is a reference you choose for the timer. AskFork does not recommend a schedule, predict a metabolic stage, or promise a result.
Choose a reference
Select 12, 14, 16, or 18 hours as a timer reference—not a health recommendation.
Edit the record
Update an active or past entry, add a past fast, or delete a record you no longer want.
Inspect the pattern
Review total, average, longest, completed count, and recorded hours by day.
Patterns, not promises
Useful records still need honest limits.
Fasting time is a log of elapsed time. Nutrition values come from a photo-based estimate. Neither is a medical measurement or proof of a health, weight, or metabolic outcome.
Today totals include only saved analyses and exclude unlogged food and drinks. AskFork is not a medical device or weight-loss program; it does not prescribe a fasting schedule, calculate a calorie deficit, predict weight loss, determine whether fasting is appropriate, or provide allergy clearance, medication guidance, or medical nutrition therapy.
Useful for
- Keeping meal timing and estimated intake in one app
- Reviewing fasting records by day, week, or month
- Editing or adding a past timing record
- Comparing logged estimates consistently
Not a substitute for
- Medical advice or individualized fasting guidance
- A food scale, verified recipe, or exact calorie count
- Allergy or food-safety clearance
- Diagnosis, treatment, or a promised weight outcome
Separate privacy choices
Fasting records stay on your device.
Fasting records are stored locally on the iPhone and are not sent to OpenAI. Food-photo analysis is a separate action: AskFork sends a newly selected image and the food context you provide only after you explicitly approve that photo. The permission resets when you select another photo.
Before you download
Fasting and calorie-tracker questions
Can I track fasting and calories in one iPhone app?
Yes. AskFork keeps a fasting timer and history alongside directional calorie and macro estimates from food photos. Nutrition values are estimates, not measurements.
Which fasting targets are available?
You can choose a 12, 14, 16, or 18-hour timer reference. The target is your reference for record-keeping, not a health recommendation or treatment plan.
Can I edit or add a past fasting record?
Yes. You can edit an active or completed entry, add a past fast, delete a record, or cancel an active timer without adding it to history.
Does AskFork require a subscription?
No. The U.S. price reviewed July 23, 2026 is US$4.99 as one paid iPhone download, including all features in the current release. Local App Store price and tax may vary.
Does fasting data leave my iPhone?
Fasting records remain on the device and are not sent to OpenAI. Food-photo analysis is separate and occurs only after you explicitly approve the newly selected photo.
Are the calorie estimates exact?
No. A photo cannot weigh the meal or reveal every ingredient. AskFork provides directional estimates and ranges that may be wrong.
Is AskFork medical or fasting advice?
No. AskFork is not a medical device or weight-loss program. It does not prescribe a fasting schedule, calculate a calorie deficit, predict weight loss, determine whether fasting is appropriate, or provide diagnosis, treatment, allergy clearance, medication guidance, or medical nutrition therapy.
Which iPhone version is required?
AskFork currently requires iOS 17 or later.
