Month end, without the chase
Stop chasing timesheets so you can bill on time
Managers spend the end of every month nagging their team over Slack and MS Teams to fill in timesheets. Without them, client billing stalls - even at 1,000-person software houses. Sandtime.io automates the nagging.
One click to approve
Managers approve or reject submitted timesheets directly from email - no app login required for routine reviews.
Past periods lock automatically
Once approved, timesheets lock so the numbers used for billing do not change after the fact.

"I built Sandtime.io because I was tired of time trackers that felt like surveillance tools. As a manager, I needed something my team would actually want to use."
Łukasz SienkiewiczFounder & CEO
Our philosophy
Designed by a manager, for managers
Sandtime.io was built in 2020 inside Sanddev, a software agency that needed accurate self-reported time for client billing without putting its own team under surveillance. That is still the design: employees self-report their time - no screenshots, no activity monitoring, no invasive tracking. Read the full story
Easy to start
Start tracking with a single click. No complex forms, no mandatory fields, no friction. Just hit start and get to work.
Privacy-first
We don't monitor apps, take screenshots, or track keystrokes. Your team's privacy is respected by design.
Trust-based
Built for workplaces where trust between employees and employers is high. Time entries are self-reported declarations, not surveillance data.
Simple & effective
Focus on what matters - your work. Sandtime.io handles the rest with timesheets, reports, and integrations that just work.

Missed revenue
Forgotten work turns into lost billable revenue faster than most teams expect
Client work rarely disappears in one obvious chunk. It leaks between Slack replies, QA passes, support pings, quick fixes, and after-hours cleanup. Sandtime.io helps teams capture the hours that usually stay invisible until the invoice is already out the door.
What 15 forgotten minutes a day really costs
A realistic month for a 10-person client-service team. Small gaps feel harmless in the moment. Across a full month, they become revenue the team already earned and delivered, but never fully invoiced.
10 billable teammates
x 15 forgotten minutes per person, per day
x 20 client days per month
50 billable hours left off the invoice
x $50.00 blended billable rate
That adds up to
$2,500.00
in missed billable revenue per month, or $30,000.00 per year.
Sandtime.io is free for unlimited users. Recovering even part of that leak goes straight to revenue and margin.
2 min
Interrupted every 2 minutes
Microsoft reports that the average employee gets interrupted roughly every two minutes. Fragmented days create work people forget to log later.
25%
Time lost to searching
Atlassian found that teams spend about 25% of their time searching for answers. Context switching is where small billable tasks disappear.
60%
Unscheduled meetings
Microsoft says about 60% of meetings happen without a calendar invite. Unplanned work is harder to reconstruct when it is time to invoice.

Loved by freelancers, consultants, and small teams
People switch to Sandtime.io to stop losing billable hours, retire the spreadsheets, and invoice without the month-end scramble. Here is what they say in their own words.
Amazing
That app is exactly what an app should look like, works perfect to have my work hours counted, and its free, amazing tool
Can't believe how amazing this app is
So amazing - where have you been all my life? Can track time for different tasks and file them under projects - will tell you when times overlap. I just love it and it's free.
Love this app!
I've been using Sandtime.io for my time tracking, and it works perfectly well for me. The app is simple, clean, and intuitive, which makes it easy to log and monitor hours without getting distracted by unnecessary features. What I like: ease of use, reliable tracking with no glitches or missing logs, smooth desktop and mobile support, and visual reports that show where time goes. It's a strong fit for freelancers, architects/designers, small teams, and anyone who wants a lightweight but powerful time tracking tool. For me, it just works - no complications.
Amazing application for time tracking
This is a really good application that solved one big issue for me: having multiple timers running at the same time. The only minor minus is the fact that it doesn't have a dark theme. I've tried others, and this was the best out there. Thanks for creating this and making it free <3
Super
For me it is a very nice app. I have not generated reports yet, but I am curious to see how it works for client billing.
Essential Time Tracking App for IT Consultants
As a professional IT consultant, I use this app every day. It helps me accurately track my billable hours across all my devices (Android, Windows, iOS). It has a clean interface and all the features I need. I highly recommend to anyone needing to keep diligent time keeping.
Great app.
A very helpful app. It is a great fit for me because I often forget to track activities right away and fill them in later, so the start and stop flow works especially well.
A must-have for freelancers
As a freelancer who manages multiple projects, this software has helped me enormously. I decide which project I will work on, select it and just start working. When I want to take a break, I just stop the activity and start a new one when I'm back. The reports are very handy, and you can create a general one for all projects, grouped by day, export it to Excel for further analysis, or send it to your clients for billing purposes. What I would like to see is API access so I can obtain my production data in real time with Sandtime.io as the source of truth instead of a master Excel file.
I love it :)
Great, simple. All I want to do in one place.

Great App
Wonderful app for keeping track of freelance projects. Would like the reporting to be a bit better but I can live with it.
OK
A very helpful app
Excellent tool
This app has incredibly helped me to keep track of all the projects I work on. You can add multiple projects and stop or restart any that you might need. I only have two issues, sometimes it doesn’t load when I press it so I have to close it and reload it again but it takes like 3 secs and I can’t add notes to it. Other than that it has been the best I have found so far and completely free! No ads
Great app but contains minor bugs
I recently went from a job in academia to a private consultant where I have to track my time across billable projects. Coming from academia, where you don’t typically track your time so closely, I found it a huge challenge to adjust. I constantly found myself neglecting to track my time and completely forgetting what I had worked on all week. This app saved my life. It makes it so easy to track your workday at the push of a button. However, the app contains minor bugs which, though annoying, do not prevent the app from being a productive tool. The most annoying bug is that sometimes the app will not allow you to stop the timer and switch to another project which usually requires restarting your computer, not just the app, to correct. More customizations for the types of statistics you want to see on the dashboard would be nice too.
Best time tracking software for teams
It’s Free :) easy to add team members and start tracking! Nothing to dislike, it’s simple and makes the job done! Just give it a try. It has all you might need from a time tracking software, and if not - well - It’s Free! ;) Time tracking for teams.
Using this tool to track how long a project takes
Just started using it a few weeks ago and loved it. Easy to use. It’s seamless to start tracking the time. Great app! I haven’t seen anything better than this.
Good
Good.
Simple, friendly and sooooo useful!
A great tool for any company
What I like the most about Sandtime.io is the ability to integrate with Slack. Easy-to-use functions to facilitate your daily work. I have not encountered any major problems in the application that would prevent me from working. The wide range of parameters in the reports can make it difficult to work with the tool at the beginning. Simple to use and helpful in project management and resource allocation. Simple payment rules for small businesses. Sandtime.io collects the time spent on my projects or clients in one place and helps me create an hourly report. Moreover, it is giving me the possibility to set individual project/client rates and generate reports. Based on that, I got rid of the extra work of filling in Excel sheets.
No more Excel for time reporting
Simplicity - just select project and hit “Start tracking”. When you have finished your work - hit “Stop tracking”. Simple as that. The feature I like the best is starting tracking of the task I was working on earlier. I fill needed data only once and then I can start and stop tracking it whenever I need. I like also the possibility to work on mobile and in desktop application - I don’t need to have browser tab with Sandtime.io open all the time. Creating reports is a little bit tricky but after a few tries you can get what you need. It is pretty powerful customizer. I recommend Sandtime.io to everyone who wants to better control their time and like playing with data in reports. It helps me in creating monthly invoice. With reports I can see how many hours did I work for selected period of time. I can also check which project took the most of my time with just few clicks.
Time tracker that doesn’t waste your time
I can start and stop time tracking with a single click - I don’t waste my time bookkeeping and I can keep my mind focused on doing my job. I’ve pinned the desktop app so when I turn on my computer and start work, I just launch the tracker from the system tray. Easy peasy! When we were still working from the office (pre-COVID times), the mobile app came in handy - I just stopped time tracking while leaving the office, having the notebook already in my backpack. When I prepare invoices for my clients, I use the reports feature with some custom made reports that help me to bill my clients precisely. I can see now how much I have to work daily, weekly, and monthly. No more unexpected over hours! Some time ago, my client required me to fill Excel-based timesheets... It was a pain to fill them daily and then resolve issues at the end of the month... And even it wasn’t accurate. I would never go back to manual time tracking. Sandtime lifts the burden from me. I love it! I have no major issues with the app. I would like it to focus more on integrations with GitHub, Jira, etc. so I could never have to launch it and forget about time tracking entirely. If you are still filling timesheets by hand, try Sandtime instead. You won’t regret that :) I invoice my clients on an hourly basis. Sandtime keeps a record of tracked time (along with information on which projects I worked on) and helps me to prepare accurate invoices. I spent way less time having to ever think about time tracking. I no longer have to fill Excel-based timesheets by hand!
Easy to learn time tracker
It is quite easy to start and stop tracking of working time, so the activities I do daily. I can do it quickly from a browser or a desktop application. Another advantage manifests itself at the end of the month when I have to sum up the entire month of work. Thanks to the reports that I can freely configure, collecting the data necessary to issue an invoice is very easy and fast: I just display the appropriate report and that’s it. I think the mobile version of the application could be more polished especially in complex views like timesheets and reports. Thanks to the notifications sent, it is easier for me to control my working time, and thanks to the reports, I can issue monthly invoices more efficiently.
Great tracker for project time
The time tracker, which I always turn on with a browser extension before starting work. Cool feature. All I need to do is select a project and click on the start button. At the end of the work, I click on the stop, and it’s ready. It’s so simple. The timesheets are filling automatically, and my boss has up-to-date information in his reports. I cannot think of anything that I dislike about Sandtime.io because it is easy to use and offers everything that I need. I recommend Sandtime.io to everyone who wants to better control their time. At work, I work on various projects. Using Sandtime.io, I know exactly how much time I have spent with each of them. It allows me to control my work better.
Time tracking app designed for managers
It’s simple but powerful. I like the most timesheets and reports. Both functionalities show me where we are with our business. There is nothing what I dislike. From my managerial point of view it is fair enough to handle daily routine. Seeing the effectiveness of my teams. Transparency of current state of software development.
