When launching a no-code app, tracking performance metrics is key to keeping users engaged and your app running smoothly. Why? Because slow load times, crashes, or errors can drive users away - 85% of US users uninstall apps due to performance issues. Monitoring the right metrics helps you identify problems early and improve user experience. Here’s what to focus on:
- Response Time: Apps should load in under 2 seconds and respond to user actions within 1 second. Slow performance can lead to a 26% drop in retention rates.
- Throughput: Measures how many requests your app handles per second. Consistent throughput ensures your app performs well under heavy loads.
- Error Rate: Tracks failures or crashes. Aim for a crash-free session rate of at least 98% to retain user trust.
- Concurrent Users: Monitors how many users are active at the same time. High concurrency can strain resources, slowing response times.
- Resource Utilization: Keeps tabs on CPU, memory, and bandwidth usage. Efficient management avoids lags and unnecessary costs.
Platforms like Adalo simplify this process by letting you build a single app and deploy it as a PWA and natively to iOS and Android app stores without rebuilding. With tools for database management and performance monitoring, Adalo helps you optimize these metrics, ensuring your app scales effectively and delivers a reliable experience.
5 Key Metrics to Track No-Code App Performance
How to Build No-Code Apps + What to Consider When Adding Subscription Services
1. Response Time
Response time measures how quickly your app reacts to user actions - from the moment it loads to every tap, swipe, or data request. It’s a key factor in shaping how users feel about your app.
Impact on User Experience
Here’s a hard truth: 88% of users abandon an app after a single bad experience. And apps with sluggish performance? They experience a 26% drop in 30-day retention rates. To keep users engaged, your app should load in under 2 seconds, respond to interactions in under 1 second, and complete critical API calls in under 200ms.
In no-code platforms, response time issues often arise from database queries, complex on-screen logic (like custom formulas), and third-party integrations such as Google Maps or Zapier. Geographic distance from servers also adds network latency.
Scalability Under Load
Even if your app feels snappy during initial testing, scaling up can introduce performance challenges. High API rate limits (e.g., 5 requests per second) or datasets with over 10,000 records can slow things down. To keep things running smoothly as your user base grows, you can:
- Optimize images to reduce data transfer.
- Simplify on-screen logic by breaking complex screens into smaller, more manageable ones.
- Use caching for frequently accessed data to minimize server requests.
For example, Adalo recently reduced initial load times for data-heavy apps by 86% through backend improvements. Using techniques like skeleton loading states or progressive loading for lists can also improve perceived response times while data fetches happen in the background.
Reliability in Production Environments
Think of response time as an early warning system for your app’s health. Monitoring it can help you catch performance issues - whether they stem from system load, resource allocation, or inefficient code - before they snowball into downtime.
"Monitoring average response times enables organizations to identify performance degradation quickly".
Tracking response times by user location can highlight issues caused by network latency or poor data center placement. For example, when CPU usage exceeds 70%, response times often take a hit as the system struggles to keep up. Regular monitoring not only ensures your app meets Service Level Agreements (SLAs) but also maintains the stability users expect in production environments.
2. Throughput
Throughput measures how many requests or transactions your app can handle within a specific time frame - often expressed as requests per second (RPS) or transactions per minute (TPM). While response time focuses on the speed of individual actions, throughput highlights the overall capacity of your system to handle work.
Scalability Under Load
High throughput is essential for scaling efficiently. For instance, Adalo processes over 20 million data requests daily across its published applications. This demonstrates the level of capacity production apps must manage to remain effective.
Under normal conditions, throughput remains consistent. However, when resources hit their limits - such as CPU usage exceeding 70% - response times increase dramatically, and throughput declines. This drop isn't just about higher demand; it's a clear sign of resource saturation. Maintaining steady throughput under pressure is key to ensuring your app scales well while keeping response times optimized.
"Throughput reveals how much work your application can handle overall." - SigNoz
For no-code apps, throughput can be limited by database queries, complex logic, or third-party integrations. Take Adalo’s API rate limit of 5 requests per second as an example. This limit becomes a crucial factor to monitor, especially as your app scales to handle more concurrent users.
These insights into throughput are essential for ensuring your app operates reliably under various conditions.
Reliability in Production Environments
Tracking throughput alongside response time helps identify real performance bottlenecks versus normal traffic fluctuations. If throughput drops while response times slow, it typically points to resource constraints or database issues.
"An application with high throughput can perform and scale better compared to an application with a lower throughput." - Joydip Kanjilal, TechTarget
To avoid throughput degradation during heavy usage, streamline database operations and offload long-running tasks. These strategies help maintain stability, even under demanding conditions.
3. Error Rate
Error rate tracks how often your app encounters failures, expressed as a percentage of total requests or sessions. This metric is key to identifying stability issues and determining where problems originate - whether it's in database queries, visual logic, or third-party integrations like Google Maps or Zapier.
Impact on User Experience
Frequent errors can quickly harm user trust. In fact, 62% of users uninstall apps after experiencing crashes or errors. Each crash not only risks losing a user but also invites poor reviews, which can hurt your app's visibility and conversion rates.
"Every crash is a potential uninstall." - Aarzu Kedia, Plotline
Industry standards suggest crash rates should stay below 0.1%, with anything under 1% considered acceptable. On average, crash-free session rates are 99.93% for iOS and 99.81% for Android. Falling short of these benchmarks can lead to an average 26% drop in 30-day user retention. Keeping error rates in check is as critical as monitoring response times when it comes to maintaining user loyalty.
Reliability in Production Environments
To measure reliability, calculate availability using the formula: (1 - Fault Rate) × 100. This calculation is also the foundation for setting error budgets, which define how much failure is acceptable while still achieving reliability targets.
In Adalo apps, common error sources include inefficient database queries (especially when handling large datasets), overly complex on-screen logic, and third-party integrations. For instance, Adalo’s API has a rate limit of 5 requests per second, which can cause bottlenecks during high traffic periods. Tools like Firebase Crashlytics can help keep error rates in check by sending automated alerts when errors exceed 2%. Aim for a crash-free rate of at least 98% to ensure a stable user experience.

4. Concurrent Users
Concurrent users measure how many people are using your app at the same time. This metric is crucial because it directly influences how well your app performs under heavy use. For instance, when multiple users are querying databases, running custom formulas, or using third-party integrations like Google Maps or Zapier simultaneously, the system's capacity is tested. Keeping an eye on concurrent users helps you maintain the right balance between speed and capacity, complementing insights from other performance metrics.
Scalability Under Load
As the number of concurrent users grows, so does the strain on your infrastructure. For example, Adalo processes over 20 million data requests daily across its platform. Individual apps, however, often face stricter limitations, such as API rate caps of 5 requests per second. When these limits are exceeded during high-traffic periods, users may experience slower response times or even errors. These challenges become even more pronounced with large datasets or complex workflows.
To maintain a smooth user experience, key API calls should ideally complete within 200 milliseconds. If response times exceed this threshold, delays become noticeable. As concurrency approaches the system's capacity, throughput decreases, and response times spike dramatically.
Reliability in Production Environments
High concurrent usage not only tests scalability but also highlights reliability issues. For example, when database connection pools are maxed out, response times can spike abruptly rather than slowing down gradually. Monitoring CPU usage is also critical - if it consistently exceeds 90% during peak times, it’s a clear signal to scale up resources. On Android, the industry standard for ANR (Application Not Responding) events is 0.63%, but aiming for less than 0.5% is a better target.
To prepare for peak usage, track your DAU/MAU ratio (Daily Active Users divided by Monthly Active Users). This ratio helps you anticipate high-concurrency periods. Additionally, using percentile metrics like P95 or P99 during traffic surges can uncover performance issues that average response times might overlook. Implementing caching and batching API requests can significantly reduce server load during these spikes.
5. Resource Utilization
Efficient resource utilization is just as critical as response time and throughput when it comes to keeping your app running smoothly. This metric measures how much of your app’s CPU, memory, disk I/O, and network bandwidth is being used. It’s a key factor that influences both user experience and your monthly hosting expenses. For example, high CPU usage can significantly slow down performance.
Impact on User Experience
Poor resource management can take a serious toll on user experience. If your app spends too much time on garbage collection, it can temporarily freeze, leading to noticeable lag. High memory usage or memory leaks can hurt both performance and scalability, often causing lags or even downtime. Interestingly, about 25% of mobile apps are used only once after being downloaded, with poor performance and usability being common culprits.
Scalability Under Load
Every database query and integration eats up resources, and if these processes aren’t optimized, they can drag down performance. For instance, CPU usage exceeding 90% is a red flag for system strain. Similarly, memory usage above 85% demands immediate attention to avoid OutOfMemory errors. Resource limitations can also vary across devices, adding another layer of complexity. By fine-tuning resource usage, you not only enhance performance but also keep operational costs in check.
Cost-Efficiency of Resource Usage
Managing resources efficiently is essential for scaling your app without sacrificing user experience. Keeping an eye on resource consumption can help you avoid unnecessary spending on infrastructure. While cloud auto-scaling can mask inefficiencies, it often leads to higher hosting bills. Striving for availability beyond 99.9%, such as 99.99%, can significantly drive up costs and complexity. For many applications, 99.9% availability strikes a practical balance between reliability and cost. To save resources and reduce expenses, consider optimizing database queries and simplifying on-screen logic.
Platforms like Adalo come equipped with real-time monitoring tools, making it easier to track resource metrics and ensure your app remains both high-performing and cost-efficient.
Conclusion
Taking a closer look at these key performance metrics, it’s evident that keeping track of them is crucial for ensuring your no-code app runs smoothly and adapts as it grows. Each metric has its own role to play: response time and throughput directly impact how users experience the app, while error rates and concurrent user capacity ensure stability under pressure.

FAQs
How can I make my no-code app faster?
To make your no-code app run faster, focus on cutting down delays in data fetching, rendering, and network activity. A good starting point is to limit the data being loaded. Instead of pulling in large datasets all at once, use filtered collections, enable pagination, or adopt lazy loading. For lists with a lot of records, break them into smaller pages or use infinite scrolling so only the visible items are rendered.
Another key area is to fine-tune media and components. Compress or resize large images before uploading to reduce their size, and remove unused components or overly complex screen layouts. Avoid deep nesting of elements, as it can slow things down. Additionally, pre-computing complex formulas in your database can save time by reducing the processing load on the client side.
Finally, work on minimizing network latency. If your primary users are in the U.S., Adalo’s servers already offer low latency. However, for users outside the U.S., you might want to cache frequently accessed data locally or use a CDN to serve static assets faster. Reduce the number of external API calls, and when they’re necessary, make them asynchronous so the app can continue loading other elements while waiting for the response. These tweaks can significantly boost your app’s performance and make it more responsive.
How can I ensure my no-code app performs well with many users at the same time?
To manage high user loads efficiently, start by fine-tuning how your app handles data. Only load the data each screen actually needs. For large datasets, implement pagination or use lazy loading to fetch additional data as users scroll. Compress images and other media files to cut down on file sizes, and cache frequently accessed data to avoid unnecessary repeated queries.
The location of your backend servers plays a big role in performance. Since Adalo’s servers are located in the U.S., users in this region will naturally experience faster response times. For a global audience, using content delivery networks (CDNs) can help ensure quicker load times across different regions. Also, reduce delays by minimizing reliance on third-party APIs, bundling related actions, and batching updates whenever possible.
Lastly, prioritize keeping your app lightweight. Simplify component structures, avoid overly complex nested relationships, and test thoroughly on a variety of devices to confirm smooth performance across iOS, Android, and web platforms. By focusing on smart data management, media compression, and streamlined design, your app can handle heavy user activity without compromising on performance.
How does resource usage affect app performance and costs?
Efficient use of resources is key to ensuring your no-code app runs smoothly and stays affordable. Every action - whether it's querying a database, executing custom logic, or interacting with third-party services - draws on CPU, memory, and bandwidth. Overloading a screen with too many operations can lead to slower load times or even crashes. On top of that, the location of your servers matters. Users farther from U.S.-based data centers may face delays, which might require additional resources to maintain performance, driving up costs.
Managing resources wisely can help you balance performance and expenses. For instance, you can optimize data queries by fetching only the fields you need or using pagination for long lists. Simplifying complex logic and cutting down on unnecessary network requests can also reduce server strain and API fees. Keeping an eye on metrics like query frequency, load times, and crash rates will help you spot inefficiencies early, ensuring your app remains fast and cost-efficient.
