Your car's records, on your iPhone. No account. No subscription. No cloud.

WHY AUTOKEEP

• 100% on-device. Your data stays on your iPhone — encrypted by iOS, never sent to a server. • No analytics SDKs, no telemetry, no advertising IDs. • No paywall. No subscription. Everything works on install. • Works offline forever. No connection required for anything except an optional VIN lookup. • Unlimited vehicles in one garage — cars, trucks, motorcycles, EVs, work assets.

MULTI-VEHICLE GARAGE

• Add unlimited vehicles, each with isolated history, fuel log, reminders and analytics. • Switch with one tap. • Archive old vehicles without losing their records. • Decode a VIN via the free NHTSA API to pre-fill year, make and model.

SERVICE & MAINTENANCE LOG

• Record oil changes, brake jobs, inspections and repairs with cost, mileage and notes. • Attach photos and receipts to any entry. • Tag entries, link them to problems you have logged, and keep a clean history per vehicle. • Add custom service categories that match how you actually maintain your car.

SMART REMINDERS

• Set reminders that trigger on date, on mileage, or on engine hours — whichever comes first. • Perfect for "every 6 months OR 10,000 km" rules. • Independent due states per vehicle so a busy garage stays organised. • Local notifications, no server required.

FUEL & ENERGY TRACKING

• Log refuels for petrol, diesel, LPG and CNG — or charging sessions for EVs. • Automatic consumption tracking: L/100 km, MPG (US or UK), or kWh/100 km. • Spot trends across months and seasons; compare cost-per-distance across vehicles.

EXPENSES & INCOME

• Track every cost: parts, labour, insurance, tolls, parking, washes. • Record income for vehicles you rent out or use for work. • See the real net cost of ownership, not just what you spent.

Whether you are tracking one daily driver, a family garage, or a small fleet — AutoKeep keeps the record straight, on the only device that matters: yours.

s3-lambda features and specs

  • Batch processing of S3 objects
    s3-lambda provides a straightforward way to perform batch operations on large numbers of S3 objects, enabling map, filter, and reduce-style processing over entire S3 buckets or prefixes without writing boilerplate code.
  • Familiar functional API
    The library uses a functional programming paradigm with operations like map, filter, and reduce, making it intuitive for JavaScript developers to process S3 objects using patterns they already know.
  • Built-in concurrency control
    s3-lambda handles parallel processing of S3 objects with configurable concurrency, allowing users to control how many operations run simultaneously and avoid overwhelming AWS resources or hitting rate limits.
  • Context-aware operations
    The library provides a context object within each operation that includes useful metadata about the current object being processed, simplifying access to S3 object properties during transformations.
  • Easy integration with Lambda
    Designed to work seamlessly within AWS Lambda functions, making it straightforward to set up event-driven, serverless pipelines for processing large volumes of S3 data without managing infrastructure.

Possible disadvantages of s3-lambda

  • Unmaintained project
    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK versions.
  • Limited documentation
    The project's documentation is relatively sparse, lacking comprehensive examples, edge case handling guidance, and detailed API references, which can make it challenging for new users to adopt effectively.
  • AWS SDK version dependency
    The library depends on an older version of the AWS SDK for JavaScript, which may conflict with projects using the newer AWS SDK v3 and could miss out on performance improvements and features in updated SDKs.
  • Limited error handling flexibility
    The built-in error handling mechanisms are relatively basic, and handling partial failures or implementing sophisticated retry logic for individual object operations requires additional custom code from the developer.
  • Narrow scope of functionality
    The library is tightly focused on S3 object processing and does not integrate with other AWS services or provide utilities beyond basic map/filter/reduce operations, limiting its usefulness in more complex data pipeline scenarios.

Analysis of s3-lambda

Overall verdict

  • s3-lambda is a useful Node.js library for performing operations like map, reduce, and filter directly on S3 objects using Lambda, making it good for developers who need efficient, serverless-based batch processing of S3 data without managing infrastructure. It is well suited for smaller to medium projects but may not be actively maintained for enterprise-scale needs.

Why this product is good

  • Simplifies common S3 batch operations (map, filter, reduce) with a clean, functional API
  • Leverages AWS Lambda for scalable, serverless parallel processing of S3 objects
  • Reduces boilerplate code for iterating over and transforming large numbers of S3 objects
  • Open-source and free to use, allowing customization for specific workflows
  • Integrates well with existing AWS infrastructure and Node.js applications

Recommended for

  • Developers building serverless data pipelines on AWS
  • Teams needing to process or transform large sets of S3 objects without provisioning servers
  • Node.js developers looking for a functional programming approach to S3 operations
  • Projects with batch processing needs that fit within Lambda's execution limits
  • Prototyping or small-to-medium scale ETL tasks involving S3 data

Analysis of AutoKeep

Overall verdict

  • I don't have verified, specific information about AutoKeep (autokeep.theassettrack.com) to make a confident assessment. This appears to be a niche or lesser-known tool that isn't well-documented in publicly available information, so I can't verify claims about its quality, features, or user satisfaction.

Why this product is good

  • Unable to confirm core features or functionality from reliable sources
  • No verified user reviews or ratings found to assess real-world performance
  • Cannot validate pricing, security practices, or company legitimacy
  • Insufficient information to compare against established competitors in the asset tracking space

Recommended for

  • Recommend researching directly via the website, checking for company registration details, and looking for third-party reviews before use
  • Consider requesting a demo or trial and checking references from existing customers
  • Best suited for users who can independently verify the tool through direct testing rather than relying on pre-existing reputation
  • Exercise caution with any asset tracking tool that lacks a strong public track record, especially if handling sensitive financial or asset data
