Creating Amphetamine is hard work.

I created Amphetamine back in 2014 as a replacement for the aging Caffeine app. Since then, countless other keep-awake utilities have sprung up (some paid, some free). While most of these apps simply replicate the original feature set that Amphetamine 1.0 offered (inspired by Caffeine), Amphetamine has grown considerably in its feature set. Amphetamine has always been, and will always remain, 100% free with no ads or in-app-purchases.

Amphetamine is the most popular keep-awake utility for macOS. It is downloaded hundreds to thousands of times every day. Some days even peak up to 26,000 downloads! And It's clear why - Amphetamine is easily the most customizable and powerful of the various keep-awake utilities, and it's free! Apple has even featured Amphetamine in a Mac App Store Story

Over the years, Amphetamine users like yourself have requested new features, reported bugs, and made suggestions to improve the Amphetamine experience. This takes time, energy, and sometimes, my own funds (example: Apple's developer program costs $99/year). While maintaining Amphetamine is a labor of love, some of you have requested a way to show your appreciation for Amphetamine through more than kind words. If you're one of those people, you can contribute to Amphetamine's development and success in the following ways:

Give a Financial Gift

By far the most popular option, you can choose to show your appreciation (and, I suppose, help motivate me to keep developing Amphetamine instead of working on some of my other million-dollar ideas) through a financial gift. 

Certainly, financial gifts are not expected or required. You won't unlock any specials features with a financial gift. If you're wondering what I spend financial gifts on, I typically purchase renewals on software licenses (supporting mostly other independent developers), or on vinyl records (supporting independent music/artists).

Tell the world how awesome you think Amphetamine is

Use social media to spread the word. Tell your friends and family to quit wasting money on other, less-capable keep-awake apps.

Rate Amphetamine on the Mac App Store

Sometimes people don't read Amphetamine's description and give a 1-star review because Amphetamine can't do something I never advertised it could do. Sometimes people get mad about a crash or bug, and instead of working with me to identify and resolve the issue, they write a bad review. Set the record straight and give your honest review of Amphetamine on the Mac App Store.

Contribute Code/Help Problem Solve

While Amphetamine is not currently open source, you can still help out with code contributions. I post questions to problems I encounter while working on Amphetamine here on Stack Overflow and here on Github.

Thank you for any and all support you provide towards making Amphetamine a huge success!
