25 prompts to build an iPhone app with AI (2026)

A habit tracker for me. Habits with a name, an emoji and a colour. Tap to tick today off, a streak on each habit, and a week grid. A daily reminder at a time I choose. Calm, soft greens.

A workout log: log exercises with sets, reps and weight, see past workouts by day, and my personal record for each lift. Kilograms or pounds in settings. A light tap when I save a set.

A private mood journal. Each day I pick a mood from five faces and write a line. A calendar of moods by colour and a chart of the month. Lock it with Face ID. Gentle and warm.

A reading list: books with title, author and status (want to read, reading, finished). Grouped by status, swipe to move a book on, a search, and how many I finished this year.

A step goal app that reads today's steps from the iPhone's motion sensors, shows progress to my goal as a ring, and a chart of the last 30 days. I set the goal in settings.

A monthly budget: a limit per category, add what I spend, and see how much is left in each category this month. Amounts in my phone's currency. Warn me when a category passes 85%.

Track my subscriptions: name, price, how often it renews and the next date. Show what I pay a month and a year in total, sorted by next renewal, with a reminder two days before each one.

Savings goals: each goal has a name, a target and a photo. I add deposits, and each goal shows a progress bar and how much a week I need to reach it by its date.

A recipe book with tabs: my recipes with ingredients and steps, favourites, and a shopping list I can fill from a recipe.

A plant care app: each plant has a photo from the camera, a name and how often it needs water. A list sorted by who needs water next, and a reminder on the day. Soft greens, rounded cards.

A chores app for our household. We each sign in, see the same list of chores, assign them to each other, and tick them off. A week view of who did what.

Flashcards for learning Spanish. Decks of cards with a front and a back, a study mode that shows cards I get wrong more often, and a count of cards learned this week. It reads the Spanish side aloud.

A focus timer for studying: 25 minutes of work, 5 of rest, with a soft tap at each change. Log each session to a subject, and show hours per subject this week as a bar chart.

Point the camera at a word or a sign in a foreign language, and the app reads the text, translates it with AI and saves it to my word list with the photo.

A booking app for my hair salon. Clients sign in, pick a service and a free time slot, and see their upcoming bookings. I see all bookings by day and can block out times. Elegant, black and gold.

A loyalty app for my café. Regulars sign in and show a code at the counter; every tenth coffee is free. A menu with photos and prices, and our opening hours with a map.

An inspection app: checklists per site, each item pass or fail with a note and a photo from the camera. Save a finished inspection with the date and location, and list past inspections by site.

A client tracker for my personal training: each client has contact details, goals and session notes. Upcoming sessions on a calendar, and a reminder an hour before each one.

A noticeboard for our running club. Members sign in, post updates with a photo, and comment. Admins can pin a post. An events list with the meeting point on a map.

A private photo board for my family. We sign in, share photos from the library with a caption, and react with a heart. Newest at the top, and an album per month.

A swap list for my street. People post things they give away with a photo and a pickup spot on a map, mark them as taken, and report a post that breaks the rules.

Record a voice note, and the app turns it into text and an AI summary with action points. Notes listed by date with a search. Clean and minimal.

Take a photo of what is in my fridge, and AI suggests three dinners I can make, with steps. Save the ones I like to favourites.

A daily word game: guess a five-letter word in six tries, with colours for right letters in the right and wrong place. A streak, stats, and a light tap on each guess.

A quiz app: I make quizzes with multiple-choice questions, friends sign in to play, and a leaderboard shows the top scores for each quiz. Bright and playful.
