aTrackr vs Wheel Builder

aTrackr – Subscription Manager Do you actually know how much you spend every month on Netflix, Spotify, iCloud, and all your other subscriptions? aTrackr gives you full control — clear, precise, and designed in the distinctive Nothing Design style. Dashboard See your total spending per month and year at a glance. The upcoming payments list shows what's due in the next few days. A built-in calendar gives you the full timeline, and an account filter lets you view spending by person. Manage Subscriptions Add any subscription with name, amount, currency, and payment interval (weekly, monthly, quarterly, or yearly). Optional fields include an end date, payment method (credit card, debit card, Apple Pay, PayPal, bank transfer), notes, and a custom color and icon. Subscriptions with an end date are automatically deactivated when that date is reached. Categories Assign subscriptions to predefined categories like Streaming, Music, or Cloud — or create as many custom ones as you like, each with its own color and icon. Accounts Manage subscriptions across multiple people or user accounts. Filter the dashboard by account to keep track of shared family or team expenses. Reminders Get notified 1 to 7 days before a charge — configured individually per subscription. Set a default value for all new subscriptions once in Settings. Statistics Analyze your spending by category, over time, or as an annual projection. Choose from multiple time ranges (3 months to all time) and spot your most expensive subscriptions at a glance. Multiple currencies are shown separately. Widget Put the aTrackr widget on your Home Screen and see upcoming payments instantly — available in four sizes: small, medium, large, and extra-large. iCloud Sync All data is optionally synced via iCloud and available across all your Apple devices. Sync can be enabled or disabled at any time. Data Backup Export all subscriptions and categories as JSON or XML — for backup or your own analysis. More Features – Pause subscriptions without deleting them – Full-text search and filters (active / paused / by account) – Sort by name or category – Light and dark mode (or follow system setting) – 5 languages: German, English, French, Italian, Spanish – No account required, no ads, no in-app purchases
