Looking for a RECaf alternative? The RECaf app vs HiCoffee and Caffeine vs Water on bedtime estimates, reminders, Apple Watch and price (Sept 2026).
The short answer
- Choose RECaf if you want the lowest-effort logger: one-tap frequent drinks, custom Siri phrases, and reminders that learn your usual time on each day of the week. 14-day free trial, then $9.99/year.
- Choose Caffeine vs Water if you want to know what's still in you at bedtime: a live caffeine curve, "You can still have ~X mg", a last-coffee time, a warning with a one-tap decaf swap, and water tracking on the same screen.
- RECaf vs HiCoffee: RECaf is about habit and logging; HiCoffee adds 2,500+ branded drinks and bedtime predictions.
- Caffeine vs Water is coming soon to the App Store; pricing isn't announced.
The RECaf app has been around since 2018 and is still updated (version 2026.1 shipped on 31 August 2026). If you're searching for a RECaf alternative, it's usually because you want something RECaf's listing doesn't describe (our best caffeine tracker apps roundup covers the wider field): a caffeine curve, a bedtime estimate, or water tracking. Here's how it compares with Caffeine vs Water and with HiCoffee.
We make Caffeine vs Water, so we're biased; here's how we checked. Every RECaf and HiCoffee fact below comes from their US App Store listings (description, version notes, privacy label, in-app purchases) and RECaf's official site and FAQ, read in September 2026. If a listing doesn't mention a feature, we say "not listed", not "doesn't have".

Where Caffeine vs Water is different
It shows what's still active, not just what you logged
RECaf's statistics are about counts and totals: items and milligrams today, 7-day and 30-day averages, time-of-day breakdowns, and how many drinks landed after your "after hours" time. Those are useful habit numbers. Caffeine vs Water adds the other half: a live curve of how much caffeine is still active, and how much will be left when you go to bed. Caffeine's half-life is around 5 hours on average but varies widely between people (see how long caffeine lasts), so 200 mg at 9 am and 200 mg at 4 pm mean very different nights.
It steps in before the drink
It's 3:40 pm and you're in the Starbucks line. You had a coffee at 8 am and go to bed at 11 pm. Caffeine vs Water shows "You can still have ~85 mg", so a 150 mg grande latte would leave about 76 mg at lights-out. Log it and the app asks first: "Log anyway", "Log a decaf instead", or cancel. The same check runs on the Watch and through Siri. It also shows the latest time a regular 95 mg coffee still fits under 50 mg at bedtime (about 2:50 pm in this example), and can remind you 30 minutes before. For the research behind the 50 mg line, read when to stop drinking coffee before bed.
Caffeine and water on one screen
RECaf deliberately focuses on caffeine; its FAQ says it was "built with a singular purpose". It can add a water entry to Apple Health when you log a drink measured in ml or fl oz. Caffeine vs Water tracks water as a first-class goal: 33 ml per kg of body weight plus the activity and hot-weather settings you choose, with every drink's volume counting, coffee included. See what counts as water intake.
Personal half-life presets
If caffeine lingers for you, you can say so: "Hits me hard" (7.5 h), "On the pill" (10 h), "Pregnant" (12 h), "I smoke" (3.5 h), "Barely feel it" (4 h), or a custom value from 2 to 15 hours. Every estimate, warning and cutoff time updates to match. The science is in caffeine metabolism and genetics.
Where RECaf is stronger
- Reminders tuned to the day of the week. RECaf learns that you have coffee at 10 am on Mondays, skip Tuesdays and have green tea at 7 am on Wednesdays, and only nudges you when you've missed your "usual". You can adjust the time right in the notification before logging.
- A source list you shape completely. Add any source, set its caffeine, unit and icon, and keep favorites and frequents one tap away. It's built for tea drinkers, soda drinkers and caffeinated medication as much as coffee.
- Custom Siri phrases for any drink you log often.
- Reads caffeine from other apps. RECaf stores entries in Apple Health and lists everything there, even items logged elsewhere. Its FAQ says the free version can still read that data.
- It's available now, with years of updates, a 4.1-star rating and iCloud backup of your preferences.
RECaf vs HiCoffee
If you're choosing between the two established apps: RECaf ($9.99/year after a 14-day trial) is the better habit tracker, with learned reminders and a customizable source list. HiCoffee (free; Premium $0.99/month, $6.99/year or $8.99 once) has 2,500+ branded coffee products, bedtime predictions, a warning before drinks that may exceed your limit, and runs on iPhone, iPad, Mac, Vision Pro and Apple Watch. RECaf is iPhone and Apple Watch only, in English. Full details are in our HiCoffee alternative comparison.
Who should choose RECaf
Pick RECaf if you've tried tracking before and kept forgetting, if you mostly want totals and habits rather than bedtime math, or if your caffeine comes from lots of non-coffee sources you want to define yourself. Note that in-app logging, custom sources and reminders are part of the paid subscription after the trial.
Who should choose Caffeine vs Water
Pick Caffeine vs Water if your real question is "will this coffee hurt my sleep?", if you want water and caffeine in one app, or if you care about privacy: no account, no ads, no analytics or third-party SDKs, and no network calls. It also covers the Apple extras: widgets, Live Activity, Control Center controls and a full Apple Watch app. Where it's behind: it isn't launched yet, it's iPhone and Apple Watch only, has no iCloud sync or data export, and its insights cover 7 days.
RECaf app pricing vs Caffeine vs Water
As of September 2026, RECaf is free to download with a 14-day free trial of all features, then a $9.99 yearly subscription (US App Store). Caffeine vs Water's pricing hasn't been announced. Meanwhile, our free bedtime caffeine calculator shows what a drink will leave at bedtime.
